CBN Grinding Wheel

CBN Grinding Wheel for HSS Woodturning Tools — 6″ (80, 180, 240, 400 Grit)

Keep your High Speed Steel woodturning tools razor sharp with a CBN grinding wheel — the premium choice for sharpening HSS chisels, gouges and scrapers. CBN stands for Cubic Boron Nitride, a ceramic abrasive that is almost as hard as diamond but with superior thermal and chemical stability — making it specifically better suited to sharpening HSS tools than either standard aluminium oxide wheels or diamond wheels.

The thermal stability of CBN is what makes it outstanding for HSS sharpening. Where standard wheels can heat the steel and draw the temper — turning the cutting edge blue and ruining the hardness — CBN wheels stay cool during grinding. No blue burning, no loss of temper, just a beautifully sharp edge every time.

These outstanding wheels have an almost indefinite lifespan when treated with respect. Unlike standard grinding wheels that wear down and need regular dressing and replacing, a CBN wheel will outlast dozens of conventional wheels — making it an investment that pays for itself many times over. And because CBN wheels can be used completely dry, there’s no need for coolant or wet grinding equipment in your workshop.

Which grit should I choose?

• 80 Grit — coarse. For heavy reshaping or repairing damaged tools. Removes material quickly
• 180 Grit — medium. The best all-round choice for regular sharpening and maintenance of HSS tools
• 240 Grit — fine. For finishing and refining an edge after coarser grinding
• 400 Grit — ultra fine. For producing the sharpest, most polished edge possible on HSS tools

For most woodturners the 180 grit is the ideal everyday choice — sharp enough to maintain a keen edge, fine enough to produce a clean finish.

Please note: CBN wheels are designed specifically for High Speed Steel (HSS) tools. For sharpening carbide tipped tools, please use our Diamond Grinding Wheel instead — it’s specifically optimised for carbide.
