FAQ

What is the difference between T27 and T29 grinding wheels?

T27 is flat and best for surface grinding, while T29 has a conical shape ideal for edge and contour grinding.

How can I extend the life of a grinding disc?

Avoid applying excessive pressure and use the disc at the recommended RPM. Store in a dry place to prevent moisture damage.

Do you offer grinding wheels for stainless steel?

Yes, we offer zirconia-based or ceramic-enhanced grinding wheels specially formulated for stainless steel to prevent discoloration and burn marks.

What sizes and grits are available?

Common sizes: 100mm, 115mm, 125mm, 180mm, 230mm. Grits from 16 to 60, with hardness grades customized upon request.

Can I order with my own brand and packaging?
