Multi-Purpose Collet (MPC) System
The Multi-Purpose Collet System was designed as an economical method of accurately holding drills, reamers, taps, boring tools, grinding wheels, etc., in all types of machining and grinding operations.
The MPC collet is a unique, quick releasing, multi-slotted collet that collapses parallel to its axis.
The metric series of MPC collets are all made to a nominal metric bore size in increments of .5MM or 1MM and will collapse .5MM to 1MM depending on collet size. Refer to the “Collet Selection Chart” — (Metric).

The slim design of the MPC Collet Holder allows a center drill and drill to be mounted in a twin turret tool holder on the CNC turning machine shown at the right. Interference would be encountered using conventional drill chucks. In addition, the drills are held more accurately on center with considerably less overhang.
All collet sets are supplied in wooden boxes.
