Jacobs J440 Metric Tap Chuck Collet, 16mm - GW 9749

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

Not what was expected
Color: Black, Size: X-Large
The shirt did not match the image on the website. While it is a button-down collar, the buttons are concealed, rather than exposed, and the material is polyester or nylon, giving the shirt a plastic sheen, which I do not like. The image on the website showed exposed buttons, and with tremors in my hands, exposed buttons are hard enough to secure.
