Note:
1. Collets are normally stocked in the fractional increments shown. All other bores are made to order.
2. Collets are available in standard and extra precision (XP) for critical applications.
3. Headstock collet bores ½ inch and larger are grooved for extra holding power. Any variation must be specified when ordering.
4. When ordering pick-off collets, please specify smooth bore.
5. If a collet used in a pick-off application requires an extended nose length, use the suffix “EN” and refer to separate section for ordering details.
6. Carbide lined collets have a wear life many times that of steel collets; in addition, they resist “galling and scratching” of problem materials.

Note:
Generally guide bushings are used in stationary or revolving guide bushings holders. For profile material, revolving bushings are essential. However, in special cases where round stock is turned in revolving bushings and extreme concentricity between the stock and the turned diameters is required, extra precision (XP) bushings are available. These bushings command higher prices, longer deliveries and should only be specified when the requirements justify their use.

Note:
Meehanite is compatible with most materials, including those which have a high tendency to “pick up”. However, meehanite has a wear life that is considerably shorter than that of carbide. Meehanite is supplied in round bore sizes only.
