Rikon Pro CBN Grinding Wheel 8 x 1 inch, 600 Grit 5/8 inch Arbor features CBN (Cubic Boron Nitride) abrasives, one of the hardest materials besides diamond! Mounted on your grinder, these wheels will put razor sharp edges on your hardened steel lathe tools - woodturning and carving gouges, chisels, plane blades and other cutting instruments. Each sharpening wheel is precision machined from solid aluminum, balanced, and bonded with fine CBN abrasives that are ideal for sharpening hardened heat-treated steel tools. CBN wheels cut quickly with minimum pressure, stay cool and never needs dressing or shaping. Wheels fit onto grinders with 5/8" shafts and work best on low-speed grinders operating below 2,000 RPMs.

This grinding wheel has 1" wide surface with 1/4" curved radius edges in 600 Grit.

Note: CBN wheels are not for use with soft carbon steel, aluminum or other soft metals which will ruin the abrasives and can void the warranty.
