Rikon PRO Grinding Wheel 8″ x 1 1/2″ CBN 180 Grit 5/8″ Arbor

These 8 x 1.5″ CBN grinding wheels are the PRO series with 1/4″ radius and 180 grit. The 5/8″ arbor hole fits most grinders. The radius on the left and right sides of the wheel makes it easy to grind small 1/4″ hollowing bits and round scrapers. This eliminates the problem of having to rotate a tool by the handle and end up over-grinding the tip. CBN – Cubic Boron Nitride abrasives is one of the hardest materials besides diamonds. 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.
