Cubic Boron Nitride (CBN) is a premium abrasive that’s exceptionally hard and long-wearing, for efficient grinding and sharpening. Only diamond is harder. Aside from the benefit of speedier sharpening, you’ll also appreciate that these 8” precision-balanced steel wheels never need to be trued, and their diameters won’t get smaller with use as other abrasive wheels will. There’s no danger of them fracturing, and they won’t go out of balance. They’re an excellent upgrade for the Laguna G8 Bench Grinder (71031, sold separately) or other high- or low-speed bench grinders with 5/8” arbor shafts.
Laguna Tools CBN Wheels Details:
- Premium CBN abrasive bonded to precision-balanced steel wheels
- Suitable for both high- and low-speed 8” bench grinders
- Diameter won’t change over time, so no need to change sharpening jig settings to accommodate a shrinking wheel
- Wheels stay balanced and can’t fracture
- 80-grit is a good choice for finer grinding tasks, such as sharpening bowl gouges or removing nicks from chisels and plane irons
- 180-grit cuts more slowly, producing a smoother edge and finer scratch pattern that requires less final honing and polishing
