Jacobs J421 Metric Tap Chuck Collet, 12.7mm - GW 9748

A collet is a specialized holding device used in machining and manufacturing processes to secure and grip a work piece or a tool in a machine tool, such as a milling machine or a lathe. It is a type of clamping mechanism designed to provide a strong and precise grip on cylindrical or round objects.

Features:

• 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 ensure maximum gripping accuracy. Hardened for greater wear resistance than split steel collets
• Each collet bore is held concentric to the old Tapers, front and back, to minimize tier
• Automatically seals tool old To prevent coolant flow through thus increasing tool wear
• Seals collets and machine spindles to protect from abrasive particles and swarf
