These are the most durable grinding wheels we offer. Besides lasting a remarkably long time, they also never need truing. And because the wheels don't get smaller over time, you won’t need to periodically adjust your sharpening jigs to compensate for wear.
Each is made of cast steel, precisely machined for accurate size and flatness, and electroplated with CBN (cubic boron nitride) particles. CBN abrasive is almost as hard as diamond, so you can grind even tough steels quickly. It's also a much better thermal conductor than the abrasives used in bonded wheels. This, combined with the heavy steel body, means the abrasive surface remains cooler – you can grind right to the tip of the tool without overheating it, so you spend less time honing afterwards.
These 6" diameter wheels come in 80x, 180x and 600x. Each comes with a pair of 1 1/2" diameter stainless-steel flanges to help minimize runout; shaft size is 1/2" for the 6" wheel/flange. 8" wheels are also available.
Premium-quality grinding wheels.
