Titan diamond grinding mandrels have a diamond concentration of 150%. These grinding pins are bonded with the famous Chrome-LOK bond. This unique bond prevents the classic problem with pins of abrasive dust covering the work surface and machine parts, thus prolonging the life of jig grinders and borers. The diamond grits are uniform in size so that all individual grains of the grinding pin are cutting at all times.

Our diamond grinding mandrels have high speed steel shanks that are centerless ground to 0.0005" Concentricity and a tolerance of + .0000"/- .0002".

All standard shanks are hardened to 42-55 Hrc. and are center-less ground to ensure a rigid, accurate, concentric and parallel pin blank.
