Typically used with cylindrical, surface, and ID grinders, these wheels are specially designed to grind the inside diameter of workpieces. They’re often used to make bearings.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Get twice the life over standard nylon mesh cushioned discs—the flexible mesh in these discs is embedded with a premium form of aluminum oxide or ceramic alumina. The mesh construction compensates for uneven pressure as you sand, producing finer and more consistent finishes compared to standard sanding discs. A special fastener on the back allows you to easily swap one disc for another. Choose the fastener style that matches your tool or backup pad.
The most common abrasive material, aluminum oxide is hard enough to sand steel and wood.
Extra coarse grade is for heavy cleaning and stripping.
Coarse grade is for deburring and removing heavy rust and surface imperfections.
Medium grade is for moderate to light cleaning, blending, and surface material removal.
Fine grade is for light cleaning, blending, and finishing.
Very fine grade is for light scratch removal, finishing, and polishing.

Fast-Cutting Nylon Mesh Cushioned Quick-Change Sanding Discs
![](/prerenderstable/mvPRE/contents/gfx/imagecache/653/6531n153c1-@halfx_ynfcf_1735938227.png?ver=imagenotfound)
The nylon mesh on these discs is embedded with precision-shaped ceramic alumina, which cuts through hard metals like stainless steel faster than other forms of ceramic alumina because of its sharp, outwardly pointed grit. The grain particles continually fracture to produce new, sharp cutting edges while maintaining their specially engineered points and angle. The design also reduces heat generation while sanding, which prevents the grit from wearing down. These discs are also good for sanding steel and soft metals.
When you need to achieve a more consistent finish, choose nylon mesh discs over paper- or cloth-backed discs. The mesh flexes to compensate for uneven sanding pressure as you sand. A special fastener on the back of these discs allows you to easily swap one disc for another. Choose the fastener style that matches your tool or backup pad.
