ERQC Quick-Change Tap Collets can be used in any standard ER-, DR- or ESX-style collet holder used on lathes manufacturers and mill centers. The ERQC collets allow industrial taps to be quickly changed without removing the collet, maintaining gauge lengths from one tap to the next. The collet has a ball bearing manufacturer tension compensating float and a solid square drive that eliminates tap slippage. Tap breakage is reduced when using synchronous (rigid) feed or machines requiring axial tension compensation.

ER-Style Collet Racks
Collet racks will help minimize damage to the precision surfaces and critical diameters of your collet. Collets which are loosely put in a drawer are subject to damage. Damaged collets may result in your cutting tools not being on the tool holders or spindles centerline, resulting in inaccurate machining.
