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.

These can be used with sealed coolant style ER collets or with standard ER collets. When using standard collets, it is recommended that a coolant sealing disc and coolant nut be used to facilitate the coolant flow through the tool.
