- Thickness: 1.0 mm discs give a narrow kerf and little material loss. Thicker discs of 2.5-4.0 mm suit heavier cutting.
- Maximum speed: check the rpm marked on the disc against your machine. Larger discs have lower limits, for example 3,800 rpm for 400 mm.
- Material: the discs are listed for carbon, structural and stainless steel. Some are also listed for acid-resistant steel.
- Abrasive and bond: corundum or aluminium oxide with a fibre-reinforced resin bond. Grits range from 24 to 60.
Typical applications
Thin 125 mm discs suit precise cuts in steel profiles, sheets and stainless steel components on site. Discs of 230 mm cut sheets, profiles and solid material. Large 300-400 mm discs are for chop saws in installation workshops, where structural steel is cut regularly.
Frequently asked questions
Why choose a 1.0 mm disc?
A thickness of 1.0 mm gives a narrow kerf, minimal material loss and cool cutting. This matters on temperature-sensitive stainless steel components.
Can the same disc cut steel and stainless steel?
Yes, many discs here are listed for both, for example the PFERD EHT 125-1.0 SG INOX and several Starflex discs. Check the product description for the exact materials.
How do I check a disc fits my machine?
Compare the diameter, bore and maximum speed with your tool. For example, 125 mm discs are rated up to 12,200-12,250 rpm and 230 mm discs up to 6,500-6,650 rpm.
