CBN Grinding Wheels suit Wood Turning Tool Sharpening by Oltre *Coming Soon - Expected Q4, 2025*

CBN Grinding Wheels by Oltre are a top choice for sharpening Wood Turning Tools. These wheels boast 4 times higher abrasive resistance, 55 times higher thermal conductivity, and twice the hardness of aluminium oxide wheels. This makes them ideal for V10 or any High Speed Steel (HSS) tools. Plus, with CBN wheels, you can sharpen without coolant as they do not overheat or burn the tools. They also offer excellent steel removal, leaving a sharp edge and smooth finish with minimal effort. Additionally, CBN wheels have a long lifespan and never need to be redressed. They can be easily mounted on a 3000 RPM or 1500 RPM bench grinder. The 200mm wheels have 40mm of grit across the width.
