The PAC Precision ER8 Collet Steel Sealed is an ER8 spring collet with a steel sealed back designed for use with coolant-through drilling and tooling. The steel seal allows coolant to flow directly through the collet's coolant channel into the tool, enabling effective through-tool coolant delivery to the cutting edge. Unlike rubber sealed collets, the steel construction does not wear over time and provides a more secure, rigid collet-to-chuck interface. Accommodates tool shanks up to 5mm diameter.
