Diamond Grinding Wheels as used on the BHI lathe turning course

Our small diamond grinding wheels are one of our most popular products and the cornerstone to many lathe turning operations. Use our diamond wheels on your lathe or mounted separately for sharpening our tungsten carbide gravers, making your own spade drills or for resharpening tools. The resin bonded diamond surface ensures that they are very hard wearing and leave a beautiful accurate finish. A high concentration of diamond provides a quick cutting surface so you can spend more time working and less time sharpening.

We offer 3 grades of diamond wheels; a medium, fine and very fine. The medium grade is solely used for shaping hard materials and saves time when removing large stock amounts. The fine grade is our all purpose most popular diamond wheel and will put a great edge on a carbide graver as well as sharpen our carbide spade drills. Lastly our very fine diamond wheel is used for finishing, this is not always necessary but the better the finished graver the better the finish on the work.

How to use our diamond grinding wheels

These diamond wheels are designed to be used dry and at slow speeds on you watchmakers lathe. A light oil may be used to help with lubrication but providing you allow the wheel to cut naturally and don't run the wheel too quickly this isn't really necessary. It is important to use the full face of the diamond wheel when sharpening and only gentle pressure is applied.

They cut cleanly, are vibration free which is essential. An excellent cutting edge can be achieved without the use of coolant." Jones & Chambault
