CBN Grinding Wheels
CBN (cubic boron nitride) grinding wheels sharpen high-speed steel and other hardened tooling cooler and more precisely than conventional abrasive wheels. This range covers 150mm flat and angled wheels, 200mm V75 beveling wheels and a 30mm notch wheel.
How to choose a CBN grinding wheel
- Match the bore and diameter to your sharpening machine. Our listed wheels come in 6mm (notch), 20mm (150mm wheels) and 32mm (200mm wheels) bores.
- Pick the profile for the grind you need. Flat 150mm wheels, angled 150mm wheels (30, 45 or 60 degree), V75 beveling wheels or the notch wheel.
- Choose the thickness. Our 150mm wheels run from 1mm to 3mm.
- Check the price band. 150mm wheels list from $231.92 to $320.32; V75 beveling wheels list at $518.96 and $574.08.

What is a CBN grinding wheel?
A CBN grinding wheel is a super-abrasive tool made from synthetic cubic boron nitride, the second-hardest material after diamond. It is used mainly to grind hardened steels and sharpen high-speed steel tools. CBN wheels run cooler than aluminum oxide or silicon carbide wheels and hold their shape, so they are commonly used without dressing or truing.
CBN Grinding Wheel FAQ
What is a CBN grinding wheel used for?
A CBN grinding wheel is used to grind hardened steels and sharpen high-speed steel tools such as cold saw blades. CBN is synthetic cubic boron nitride, the second-hardest material after diamond.
Do CBN grinding wheels need dressing?
Generally no. CBN wheels hold their shape and are used without dressing or truing.
How do I know which CBN wheel fits my machine?
Start with bore and diameter, then profile and thickness. Our listed wheels use 6mm, 20mm and 32mm bores. If you are unsure, call 800.397.8511.
Do you carry wheels that are not listed?
Yes, we can often source other wheels, including chamfering, chip breaker/notch and A Grind style wheels. Call 800.397.8511 or send an inquiry with your machine and the profile you need.
Can you sharpen my cold saw blades instead?
Yes. We offer CNC saw blade sharpening.
