Draper 250 watt 6 inch grinder. With 150 x 20mm coarse and fine grey aluminium oxide wheels. Continuously rated well made grinder with machined flanges (not pressed), dust protected on/off toggle switch. The 12.7mm shaft will take wider wheels. Our 150 x 25mm microcrystalline wheel will perform well on this machine and do a great job on your HSS turning tools. We recommend that you replace at least one grindstone with a microcrystalline wheel then your grinder will be able to sharpen just about every type of blade including carbon steel chisels and turning tools which require a cool cutting wheel.
