Crowned CBN (Cubic Boron Nitride) grinding wheels provide a precise, clean, and cool-running alternative to bonded abrasive grit wheels. We worked with Woodturners Wonders to design a wheel specifically for hollow-grinding chisels, plane irons, and other woodworking tools. Joel has long been a proponent of hollow-grinding chisels and plane irons, because it makes honing so much easier. However, for many folks even high-quality bonded abrasive wheels are too dusty, difficult to maintain, or challenging to dress.
