Selecting the right pipe saw means matching the machine to the complete pipe specification and the conditions in which you will use it. Outside diameter is the most visible filter, but it is rarely the only one that matters. Wall thickness, pipe material, working environment, available power, and required output all influence which machine will perform reliably and which will struggle or fail. A machine rated for the right diameter but wrong wall thickness wastes blades and time. A machine suited to dry workshop conditions is a safety hazard in a flooded trench.
This guide covers every current model in the Exact Tools pipe saws range. It is structured so that contractors, fabricators, industrial maintenance teams, and procurement professionals can work through their own specification and arrive at a clear recommendation. We cover material, diameter, environment, blade selection, and common mistakes, then close with a checklist you can send directly to our team if you want a confirmed recommendation before purchasing.
What Information Do You Need Before Choosing a Pipe Saw?
Before comparing machines, gather the full pipe specification for your project or your typical workload. Choosing on diameter alone is the most common mistake buyers make, and it leads to machines that cannot reach the wall, blades that work-harden the material, or power sources that are incompatible with the site. The following inputs each change the recommendation in a meaningful way.
Pipe Material
Carbon steel, stainless steel, cast iron, ductile iron, copper, aluminium, plastic, composite pipe, and spiral ventilation duct all behave differently under a rotating blade. Stainless steel and acid-resistant alloys work-harden quickly if the blade speed or tooth geometry is wrong, which destroys blade life and produces a poor cut surface. Cast iron is brittle and requires a different disc type entirely. Large-bore plastic pipe needs higher blade speed and a tooth profile optimised for thermoplastics rather than metal. If you cut a single material family consistently, a dedicated machine configuration gives better blade life and more consistent results than a general-purpose machine with a compromise blade.
Outside Diameter and Wall Thickness
Outside diameter sets the minimum machine capacity. Wall thickness determines whether the machine’s cutting depth is sufficient. Both figures must be confirmed before selecting a model. A machine rated to 220 mm OD with a maximum steel wall capacity of 8 mm cannot cut a 220 mm pipe with a 12 mm wall, regardless of how it is set up. Always check both specifications on the product page, not just the headline diameter figure. If you cut across a range of pipe sizes, identify the largest OD and the thickest wall you encounter and use those as your selection criteria.
Required Cut Quality and Output
A square, clean cut is the baseline for all Exact Tools machines. Whether that cut then needs to be weld-prepped, threaded, or mechanically joined determines whether you need a beveller alongside the saw. If you are producing high volumes of identical cuts in a prefabrication environment, throughput and consistency matter as much as raw capacity. If you are making occasional cuts on a maintenance job, portability and setup time are more important than production rate.
Power Availability
Most machines in the range run on 230 V or dual 110 V and 220 V mains. Battery models remove the cable entirely. Hydraulic models require an external hydraulic power unit. If your site has no mains supply, or if running a cable to the work location is impractical, you need a battery or hydraulic machine. If you work across international projects, confirm whether a dual-voltage model is available for the machine you are considering.
Working Environment, Access, and Production Volume
A dry workshop with good access is the least demanding environment. A flooded pipe chamber, a confined ceiling void, a deep trench, or an offshore installation each impose additional constraints. Wet conditions eliminate electric machines on safety grounds and point directly to the HYDRA hydraulic series. Confined spaces favour compact, lightweight machines over large-frame models. High daily production volume favours machines with robust drive systems and easy blade changes. Consider all of these factors before narrowing the model list.
Exact Pipe-Saw Families Compared
The Exact Tools range is organised into families, each designed around a specific set of application requirements. Understanding the purpose of each family is faster than comparing individual models one by one.
Classic Series
The Classic series covers the most common pipe sizes in plumbing, heating, and light industrial work. The PipeCut 170E handles pipe from 15 to 170 mm OD on a 230 V mains supply, with a maximum steel wall of 8 mm and a maximum plastic wall of 14 mm. It is compact and light enough for ceiling voids and confined spaces. The PipeCut 170 Battery delivers the same cutting envelope in a cordless format for sites without convenient power access. The PipeCut 220E extends the OD range to 220 mm while retaining the mains-powered format. Classic machines are the right starting point for contractors whose pipe sizes fall within these ranges and who do not regularly encounter heavy wall thicknesses that exceed the published capacity.
The Classic series is not designed for sustained heavy-wall production. If you regularly cut steel walls above 8 mm or need to work across a wider OD range at industrial pace, the Pro Series is the appropriate step up. If you are deciding between the 170E and the 220E, a dedicated comparison examines which Classic saw fits your pipe sizes in detail.
Pro Series
The Pro Series is built for heavier wall thicknesses and more demanding production environments. The PipeCut 220 Pro Series 2.0 covers 20 to 220 mm OD with a maximum steel wall of 16 mm and a maximum plastic wall of 35 mm, available at both 110 V and 220 V. The PipeCut 360 Pro Series 2.0 extends the range to 75 to 360 mm OD, with a maximum steel wall of 16 mm at 110 V and 20 mm at 220 V, and a maximum plastic wall of 50 mm. The PipeCut 460 Pro Series 2.0 raises the OD ceiling to 460 mm, making it suitable for large-diameter industrial pipe, process pipework, and district heating steel mains.
The Pro Series machines are dual-voltage where noted, which makes them practical for UK and international site power without an additional transformer. If you are weighing the 220 and 360 Pro Series against each other, the comparison article on where the step up pays for itself sets out the practical difference. For those deciding between the 360 and 460, a separate article covers reading the capacity line correctly for each model.
INOX Series
The INOX series is configured specifically for stainless steel and acid-resistant pipe. Stainless steel work-hardens rapidly under incorrect cutting conditions, and using a general-purpose machine with a standard steel blade produces poor cut quality and short blade life. The INOX 220 covers pipe up to 220 mm OD on a 230 V supply. The INOX 360 extends the range to 360 mm OD. Both machines are optimised in terms of blade speed and configuration for the cutting characteristics of stainless and acid-resistant alloys.
If stainless steel makes up a significant share of your daily work, a dedicated INOX machine gives better blade life and more consistent cut quality than a Pro Series machine with a stainless-rated blade. The comparison on when stainless justifies a dedicated machine sets out the cost and quality case in detail.
Infinity Series
When pipe OD reaches 360 mm and above, the PipeCut Infinity 2.0 takes over from the fixed-frame orbital machines. It handles pipe starting at 360 mm OD and reaches up to 1850 mm with the supplied chain set. The chain set can be extended further with additional sections, so the machine grows with the project. The maximum steel wall capacity is 16 mm at 110 V and 20 mm at 220 V, with a maximum plastic wall of 43 mm. It uses a chain-type gripping mechanism that clamps directly to the pipe and orbits around it, and it runs on 110 V or 220 V mains.
The Infinity 2.0 is the answer when pipe OD simply exceeds what any fixed-frame machine can accommodate. The article on when a gripper unit runs out of pipe explains the crossover point clearly. For a full walkthrough of setup, chain extension, and blade selection for large-diameter steel pipe cutting, see the dedicated guide.
HYDRA Series
Electric motors and standing water create a safety hazard. The HYDRA series replaces the electric drive with a hydraulic motor powered by an external hydraulic unit, making it suitable for wet trenches, flooded pipe chambers, and fully submerged cutting. The PipeCut HYDRA 360 covers pipe up to 360 mm OD. The PipeCut HYDRA Infinity handles pipe from 360 mm OD upwards in the same wet and submerged conditions. There is no electric machine in the range that safely replicates this capability, and no electric machine should be used as a substitute where hydraulic power is the appropriate choice.
Plastic and Ventilation Series
Plastic pipe and spiral duct require higher blade speeds and different tooth profiles compared to metal pipe. The PipeCut P400E and PipeCut P400 Battery both cut plastic pipe up to 400 mm OD, with the battery version suited to mobile work without a cable. The PipeCut P1000 handles plastic pipe up to 1000 mm OD, covering large district heating casing, large-bore drainage, and industrial plastic mains. The PipeCut V800E is purpose-built for spiral duct and ventilation pipe up to 800 mm OD, and is the correct tool for HVAC installers cutting large round duct sections. Browse the full plastic and ventilation saws range to compare these models directly.

Which Pipe Saw Should You Choose by Material?
Material is often the most decisive filter after outside diameter. The following guidance routes each common pipe material to the appropriate machine family and flags where blade selection becomes the next decision.
Carbon steel is the most common material across the range. Classic machines handle standard schedule carbon steel within their OD and wall limits. Pro Series machines are the right choice for heavy-wall carbon steel or where production volume demands a more robust drive system. The 360 Pro Series 2.0 at 220 V reaches 20 mm steel wall, which covers the majority of industrial pipe schedules up to 360 mm OD.
Stainless steel and acid-resistant alloys require a dedicated approach. The INOX 220 and INOX 360 are configured for these materials and give better blade life and cut quality than a general-purpose machine. If stainless represents only an occasional cut rather than a daily material, a Pro Series machine with a stainless-rated blade is a practical alternative, but blade life will be shorter. For a complete stainless workflow, the guide to building a complete stainless setup covers machine, blade, and support combinations.
Cast iron and ductile iron are brittle materials that require a different disc type from standard steel blades. The guide to the right disc for cast iron and ductile iron pipe covers machine and disc selection in detail. Do not attempt to cut cast iron with a TCT or Cermet blade intended for steel or plastic.
Plastic pipe in standard diameters can be cut by Classic and Pro Series machines with the appropriate plastic blade. For large-diameter plastic pipe above 400 mm OD, the P400E, P400 Battery, or P1000 are the correct machines. The article on matching machine and blade to your plastic type covers HDPE, PE, PP, and PVC in detail.
Aluminium and copper are softer materials that cut cleanly with the appropriate blade on Classic or Pro Series machines within the published OD and wall limits. Confirm blade compatibility before cutting these materials.
Composite and multi-layer pipe is common in heating and plumbing installations. Classic machines with a TCT blade handle the most common composite pipe sizes. Confirm the pipe OD and wall against the machine’s published capacity before selecting.
Spiral duct and ventilation pipe require the V800E, which is purpose-built for thin-wall, large-diameter duct geometry. Using a standard pipe saw on spiral duct risks deforming the material and producing an unusable cut. For the geometry and blade speed reasons behind this, see the guide on why thin-wall duct needs its own saw.
For all material-to-blade questions, the blade selection guide covers TCT, Cermet, INOX, ALU, and Diamond types across the full range of compatible machines.
Which Pipe Saw Should You Choose by Diameter?
Outside diameter organises the range into clear tiers, but wall thickness, material, and access conditions can each shift the recommendation within a tier. Use the diameter ranges below as a starting point, then apply the other filters.
Up to 170 mm OD: The PipeCut 170E and PipeCut 170 Battery cover this range. These are the most compact machines in the range and are suited to the pipe sizes found in the majority of plumbing and heating installations. Confirm that your wall thickness falls within the published steel or plastic wall limit before selecting.
171 mm to 220 mm OD: The PipeCut 220E covers this range in a Classic format. For heavier wall thicknesses within this OD range, the PipeCut 220 Pro Series 2.0 is the correct choice, with a maximum steel wall of 16 mm compared to the 220E’s lighter capacity. The comparison between the 220E and the 220 Pro Series 2.0 explains where the Pro Series becomes the stronger option.
221 mm to 360 mm OD: The PipeCut 360 Pro Series 2.0 covers 75 to 360 mm OD and is one of the most versatile machines in the range. It handles a wide spread of pipe sizes in a single machine, which makes it a strong choice for teams that cut across many diameters. For stainless steel in this range, the INOX 360 is the dedicated option.
361 mm to 460 mm OD: The PipeCut 460 Pro Series 2.0 is the fixed-frame machine for this tier. Large-diameter industrial installations, process pipework, and district heating steel mains are its natural territory.
Above 460 mm OD: The PipeCut Infinity 2.0 is the only electric machine in the range that reaches beyond 460 mm OD, with published capacity up to 1850 mm using the supplied chain set and further with additional chain sections. For wet or submerged conditions at these diameters, the PipeCut HYDRA Infinity is the appropriate machine.
Which Solution Fits Your Working Environment?
The working environment is as important as the pipe specification. A machine that performs correctly in a dry workshop may be unsuitable, impractical, or unsafe in a different setting. Consider each of the following scenarios before finalising your selection.
Workshop and prefabrication environments offer stable power, good access, and consistent conditions. In this setting, throughput and cut consistency are the priorities. Pro Series machines at 220 V, paired with pipe supports and a beveller, are well suited to high-volume prefabrication work. The PipeCut 460 Pro Series 2.0 is a strong choice for large-diameter workshop production, and pairing it with a Pipe Beveller 360E and pipe supports creates a complete cut-and-bevel station.
Construction sites and open trenches introduce variable power availability, uneven ground, and the need for a machine that can be moved quickly between locations. Dual-voltage Pro Series machines are practical where site power varies. Battery models eliminate the cable entirely. Pipe supports become more important on uneven ground, where manual holding is impractical and unsafe for larger pipe.
Restricted access and confined spaces favour the most compact machine that meets the pipe specification. The Classic series machines are the lightest and most manoeuvrable in the range. If the pipe size falls within the Classic range, a compact machine is easier to position in ceiling voids, plant rooms, and narrow trenches than a larger Pro Series frame.
Wet conditions and submerged pipe require the HYDRA series. Electric machines must not be used in conditions where the machine or the operator is at risk from standing water or submersion. The HYDRA 360 and HYDRA Infinity use hydraulic drive from an external power unit, which removes the electrical hazard. If you are working in a flooded pipe chamber, a wet trench, or a submerged pipe environment, the HYDRA series is the only appropriate choice from the Exact Tools range. A full comparison of hydraulic versus electric pipe saws in wet and submerged conditions is available for projects where the environment is variable.
Large-diameter infrastructure projects where pipe OD exceeds the fixed-frame capacity of the Pro Series require the Infinity 2.0 or, in wet conditions, the HYDRA Infinity. These projects often involve heavy-wall pipe in addition to large OD, so confirm the wall thickness against the published capacity at the relevant voltage before proceeding.
How Blade Selection Affects the Machine Configuration
Every machine in the range ships with a starter blade, but the blade included may not be the optimal choice for every material you cut. Blade selection is the second decision after machine selection, and it has a direct effect on cut quality, blade life, and the suitability of the machine for a given material.
The Exact Tools range includes TCT, Cermet, INOX, ALU, and Diamond blade types. Each is designed for a specific material family or a defined range of materials. Using a TCT blade intended for carbon steel on stainless steel will work-harden the cut surface and destroy blade life quickly. Using a plastic-optimised blade on steel produces a dangerous and unusable result. The relationship between machine, material, and blade is not interchangeable, and selecting the wrong blade negates the advantage of having the right machine.
Not every blade fits every machine. Blade diameter and bore must match the machine’s published compatibility. Before ordering replacement or additional blades, use the compatibility reference on which blade fits which PipeCut machine to confirm the correct specification. If your crew cuts across multiple material families, carry a blade for each material rather than using a single compromise blade across all of them.
For a complete breakdown of blade types, material compatibility, and tooth geometry, the blade selection guide covers the full range. Browse the pipe-cutting blades range to find the correct specification for your material and machine combination.
Common Pipe-Saw Selection Mistakes
The following mistakes appear consistently across the range of enquiries we receive. Avoiding them before purchasing saves time, cost, and frustration on site.
Selecting from diameter alone. Outside diameter is the most visible specification, but it is not the only one that determines suitability. A machine rated to the correct OD may still be unable to complete the cut if the wall thickness exceeds its published capacity. Always confirm both OD and wall thickness against the product specification.
Ignoring wall thickness. This is the most common consequence of the mistake above. Standard pipe schedules vary significantly in wall thickness across the same nominal diameter. A machine that cuts standard-wall pipe in a given OD may not cut extra-heavy or thick-wall pipe in the same OD. Check the wall thickness on the product page, not just the diameter range.
Using the wrong blade for the material. A machine configured correctly for the pipe size will still produce poor results if the blade is wrong for the material. Stainless steel cut with a carbon-steel blade, plastic cut with a metal blade, or cast iron cut with a TCT blade are all examples of mismatched configurations that produce short blade life and poor cut quality. Refer to the blade selection guide before selecting a blade for a new material.
Overlooking power availability. Arriving on site with a 230 V mains machine and no mains supply is a preventable problem. If your work takes you to locations without reliable mains power, identify this before purchasing and select a battery or hydraulic model accordingly. Dual-voltage models reduce the risk for international work, but they still require a mains supply.
Insufficient pipe support. Large-diameter or heavy pipe that is not properly supported during cutting is a safety risk and produces inaccurate cuts. Pipe supports are not optional accessories for large pipe; they are a functional requirement. The pipe supports range includes options sized to match different machine models and pipe diameters.
Assuming one machine is optimal for every material. A single machine with a range of blades can handle multiple materials, but it is not always the most efficient or cost-effective approach. If your work is predominantly stainless steel, a dedicated INOX machine gives better results than a Pro Series machine with a stainless blade used daily. Match the machine configuration to the dominant material in your workload.

Why Exact Tools Is the Best Choice for Professional Pipe Cutting
Exact Tools designs and manufactures portable orbital pipe-cutting machines for professional use across construction, process industry, utilities, shipyards, and infrastructure. The range covers pipe from 15 mm to 1850 mm OD, across steel, stainless steel, cast iron, plastic, aluminium, copper, composite, and ventilation duct, with machines configured for dry workshop conditions, open construction sites, confined spaces, and fully submerged environments. No other single range covers this breadth of application with the same level of application-specific configuration.
Every machine in the range is supported by a published blade compatibility system, a full set of current manuals, and a structured selection guide that routes buyers to the correct machine for their specification rather than the highest-margin option. We work with pipe fitters, contractors, fabricators, plant purchasing teams, and distributors across more than eighty countries, and we apply that application knowledge directly when helping buyers make a selection decision.
The system approach is what separates Exact Tools from a machine-only supplier. A machine paired with the wrong blade, without adequate pipe support, or used in conditions outside its design envelope will underperform regardless of how well the machine itself is built. We provide the machine, the correct blade or blades for the material, the pipe supports, the bevellers where weld preparation is required, and the technical guidance to configure the complete cutting station correctly for the application.
