This industrial-grade set of diamond burrs can be used for general shaping, grinding and sharpening.
They are 1 3/4" long, and have shanks just under 1/8" dia. At about 350 grit, they are fine enough for detailed work, yet won't easily load up. Our best-quality diamond points.
Operate at a minimum 12,000 rpm and a maximum 30,000 rpm.
