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 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.
