Cratex Wheels Knife Edge-Packs of 10

XF] EXTRA FINE (Grey Green) Cratex Standard Bond The Cratex bond common to each of the four Grit Textures is made with premium grade oil-resistant chemical rubber. In contrast to conventional grinding wheels the Cratex bond has unique cushioned action...cuts freely, smoothly and softly without gouging or digging into the work surface. It resists clogging or smearing, and is ideal for a broad range of applications where metallic or non-metallic surfaces must be smoothed and polished without loss of dimensional tolerances or control. Cratex Abrasive Type The abrasive type used in Cratex Rubberized Abrasives is premium-quality Silicon Carbide that has been washed, dried and treated to remove impurities and then carefully screened to U.S. Department of Commerce standards for size. Although silicon carbide is more expensive than other abrasive materials, it is used because it has a high level of purity and has been found to be best for the broadest range of light deburring, smoothing, cleaning and polishing applications on ferrous and non-ferrous alloys as well as many non-metallics, such as glass.
