Ordering the wrong blade costs you more than the blade itself. It costs you a ruined cut, a damaged machine, and time you cannot get back. If you are about to place a consumable order and are not certain which pipe saw blade selection is right for your material, this guide is the page to read first. For help choosing a machine before you choose a blade, see our complete pipe saw model comparison.
Every blade and disc in the range is covered below, including which pipe cutting blade to use for each material, what shortens blade life, and how to place your order.
Blade First or Machine First?
Your pipe saw model determines which blade diameters fit. Before selecting a blade family, confirm the blade diameter your machine accepts. The tables below cover 140 mm, 165 mm, 180 mm, 190 mm, and 250 mm formats across the range. For our detailed compatibility and cutting depth charts, refer to the dedicated blade selection resource.
Once you know your diameter, material drives everything else. The sections that follow break down each blade family by tip technology, intended material, and available sizes.

TCT Blades: Tungsten Carbide for General Use
TCT blades are the right starting point for most carbon steel, copper, and multi-layer pipework. Tungsten carbide tips handle a wide range of wall thicknesses and deliver clean, straight cuts without the heat or sparks of an angle grinder.
Three general-purpose options are available. The TCT 140 is the standard 140 mm general-purpose blade. The TCT Z140 is also 140 mm but is positioned for occasional pipe cutting rather than continuous production use. The TCT 165 steps up to 165 mm for machines that accept the larger format. If you are weighing options within the 140 mm format, a dedicated guide covers the 140 mm decision in detail.
For plastic pipe, the TCT P sub-family is purpose-built. The TCT P150, TCT P190, and TCT P250 cover 150 mm, 190 mm, and 250 mm diameters respectively, and are made for PVC, PE, HDPE, and PP pipe.
Cermet Blades: Ceramic Tip Technology for Heavy-Duty Work
When you are cutting harder materials or running high volumes, Cermet blades outperform standard TCT in those conditions. The ceramic metal tip technology is built for demanding applications where a general-purpose blade wears faster than you want.
Comparing TCT vs Cermet blade performance comes down to material hardness and cutting frequency. For occasional cuts on standard carbon steel, TCT is sufficient. For sustained production cutting or harder alloys, Cermet is the better choice.
Four standard Cermet options are available: the Cermet 140, the Cermet 140 THIN for thinner-wall profiles, the Cermet 165, and the Cermet 180.
The Cermet V155 is a separate product designed specifically for very thin-wall ventilation pipes. It is approved for use only with the V800E machine. Do not use the Cermet V155 in any other pipe saw.
INOX Blades: Purpose-Built for Stainless Steel
Stainless and acid-resistant steel pipes demand a dedicated pipe cutting blade for stainless steel. Using a general-purpose TCT blade on stainless work-hardens the material at the cut face and shortens blade life significantly.
The INOX family uses ceramic tip technology matched to the properties of stainless and acid-resistant grades. Two sizes are available: the INOX 140 and the INOX 140 Thin for thinner-wall stainless pipe. For further guidance on matching a blade to stainless work, a dedicated setup guide covers the full picture.
If your work involves stainless regularly, keep INOX blades as your standard stock. Substituting another family is a false economy.
ALU Blades: For Aluminium Pipe Cutting
Aluminium requires its own blade geometry. The ALU family uses tungsten carbide tips configured for the softer, gummy cutting behaviour of aluminium, preventing the blade from loading up and stalling.
Three diameters are available: the ALU 140, ALU 165, and ALU 180. Match the diameter to your machine specification.
Diamond Discs: Cast Iron and Glass Fibre
Cast iron and glass fibre pipe cannot be cut cleanly with a toothed saw blade. Diamond discs abrade rather than chip, which is what both materials require. Using a conventional blade on cast iron risks tip fracture and an unsafe cut.
The Diamond X series covers three diameters: Diamond X140, Diamond X165, and Diamond X180. The distinction between a diamond disc vs saw blade is not about preference but about material suitability. For cast iron and glass fibre, diamond is the correct choice.
Cut and Bevel Blades and Discs
When your joint preparation requires a 15-degree bevel, the Cut and Bevel range completes the cut and the bevel in a single pass. That eliminates a separate deburring or beveling step on site.
Two formats are available. The Cut and Bevel blade 190 handles plastic pipe. The Diamond Cut and Bevel disc 165 handles cast iron and glass fibre pipe. Both deliver a 15-degree bevel alongside the straight cut.

What Shortens Blade Life?
Blade life is determined mostly by how the blade is used, not just what it cuts. These six factors are the most common causes of premature wear.
- Wrong blade for the material. Each family is designed for specific material properties. Fitting a TCT general-purpose blade to stainless steel, for example, accelerates tip wear and degrades cut quality faster than the correct INOX blade would.
- Forcing the feed. Pushing the machine through the cut faster than the blade can clear the kerf generates excess heat and load on the tips. Let the blade do the work at its own pace.
- Cutting a material the blade is not made for. Using a plastic blade on steel, or a toothed blade on cast iron, risks tip fracture and can create a safety hazard. Always match the blade to the material.
- Worn or damaged tips left in service. Continuing to cut with chipped or worn tips puts uneven load on the remaining tips and damages the blade body. Inspect blades regularly and retire them when tip condition drops.
- Poor pipe support causing the blade to bind. If the pipe is not properly supported and clamped, it can close on the blade mid-cut. Binding stresses the tips and the blade body, and can cause kickback.
- Running a blade past the point where cut quality drops. A blade that is leaving rough or out-of-square cuts is already past its productive life. Continuing to use it does not recover value; it wastes time on remediation and risks the workpiece.
