Diamond Whetstones

Our professional quality Diamond Whetstones are British made. As used by British Aerospace and Rolls Royce. Double sided with medium and fine finish. The perfect way to keep your high-speed steel cutters honed to perfection.

Sharpening Tips:

Make sure that you back off behind the land if the bit blackens in use. High speed steel is recommended to work at high temperatures, but blackening means that they are not cutting.

Sharpening bits with a diamond whet depends on your finding the flat ‘land’ behind the bit, and keeping the bit flat on it while you work it to and fro without turning it over onto the finished edge. Try it. Once you have the knack there’s no need to send bits away for sharpening.
