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

Highly recommend
Size: 100 Feet
I was pleasantly surprised about the quality of this wire. Very easy to use. Flexible yet truly 18 gauge copperwire. The insulation is good. I used this wire to run some cab lights inside my fishing boat. I also ran battery charge level indicators and a phone charge. I highly recommend this wire.

Good quality wire, but thicker than expected
Size: 100 Feet
The wire itself is great quality — sturdy and well-insulated. I bought it to wire up several COB LED lights, but the individual wires and outer sheath were a bit too thick to fit into the press connectors I was using. It’ll work perfectly for other projects, just something to keep in mind if you’re using tight-fit connectors.
