RIKON PRO CBN 8 Inch x 1.5 Inch x 1 Inch Square Edge 80 Grit Sharpening Wheel, 5/8 Inch Arbor

RIKON PRO CBN 8 Inch x 1.5 Inch x 1 Inch Square Edge 80 Grit Sharpening Wheel, 5/8 Inch Arbor

These 8 x 1.5" grinding wheels are the PRO series CBN (Cubic Boron Nitride) one of the hardest materials besides diamonds, with 80 grit. The 5/8" arbor hole fits most grinders. CBN grinding wheels are ideal for low-speed grinding in ferrous, hardened, heat-treated steel. They have a square 1 inch side to the wheel. Mounted on your grinder, these wheels will put razor sharp edges on your hardest steel tools, gouges, chisels, plane blades and others. Each wheel is machined from solid aluminum, balanced and bonded with fine CBN abrasives. They cut quickly with minimum pressure, stay cool and never need dressing or shaping. Work best on low speed grinders below 2000 RPM.
