CBN Grinding Wheels


Cubic Boron Nitride (CBN) grinding wheels are a very popular abrasive wheel. CBN wheels have 4 times higher abrasive resistance, 55 times higher thermal conductivity and twice the hardness of aluminium oxide wheels. They are ideal for sharpening all Wood Turning Tools, including V10 or any High Speed Steel (HSS) tools.

One of the advantages of CBN wheels is that you can sharpen without the requirement of coolant as the wheels don't overheat or burn the tools. These wheels provide excellent removal of steel whilst also delivering a sharp edge and smooth finish with very little effort. CBN wheels have a long life as they never need to be redressed. These wheels can be mounted on a 3000 RPM or 1500 RPM bench grinder.

Our 200mm Vicmarc CBN wheels have 40mm of grit across the width as well as 40mm of grit on the outer face whilst the 150mm CBN wheels has 40mm across the width and 30mm on the side face.
