Gemtex (Toronto, Ontario) is the exclusive manufacturer in the world for Trim-Kut discs. Trim-Kut is an abrasive disc designed to grind and finish a wide variety of materials faster and cooler than any other abrasive disc available today. The patented process of fusing premium aluminum oxide, zirconia, ceramic & silicon carbide grain, as well as surface conditioning material, to a durable polymer backing results in a highly versatile grinding tool that requires no backing pad and is readily trimmable to either renew the cutting surface or reduce the diameter.
Trim-Kut discs are available in 3”, 4 ½” and 5” for use on a drill, die grinder and right-angle grinder. When the outside edge is loaded or worn to the point where it is not grinding effectively, trim it off.
