Unique in design and operation, the Jacobs® Rubber-Flex® Collet can generate two to three times the gripping power of a conventional splitsteel collet. • Parallel jaw insert surfaces exert uniform, accurate gripping force up to three times greater than can be achieved with split-steel collets • Each collet accepts and precisely centers a wide range of both decimal or metric diameters (within individual capacity ranges) to speed setups and increase machining productivity • Durable one-piece construction • Synthetic rubber retains flexibility and resists deterioration from heat, coolants and cutting compounds • Steel jaw inserts precision ground (after molding process) to assure maximum gripping accuracy (parallelism) • Hardened for greater wear resistance than split-steel collets • Each collet bore is held concentric to the O.D. tapers, both front and back, to minimize TIR • Automatically seals tool O.D. to permit coolant flow through tool reducing wear • Seals collets and machine spindles to protect from abrasive particles and swarf
