|Coolant Fed / Coolant Thru ER Collet Sleeves
Specifically designed for use with High-Pressure coolant delivery systems, these collet sleeves feature NPTs built in for easy integration into your coolant system. A cost effective way to add coolant-thru capability to your drilling or boring applications.
