Carbide Lined Collets for the above machines are available on request. Carbide lined collets have wear ratio many times that of steel collets and also resist “galling” and “Scratching” on problem materials.

Steel Collets are available in round, hexagon, square or profile bores.

Inclined slotted collets, frequently used on pinion stock, are available for all machines.

The above bushings are also available in meehanite and steel. Meehanite bushings are compatible with all materials, including stainless steels, but have a shorter wear life. Steel bushings are normally used for brass, nylon or other materials that are compatible with steel. All of the push bushings listed are available in round bores only.
