9/16" ER32 Internal Coolant Collet

• Sealed Design: Prevents coolant leakage for through-tool cooling applications.
• Exact Size Fit: No collapse range—engineered to match the specific tool shank diameter.
• High Pressure Rated: Pressure tested to withstand up to 1000 psi.
• ER32 Compatible: Fits standard ER32 tool holders with 33 mm diameter and 40 mm length.
• Precision Ground: Ensures excellent concentricity and stable performance during machining.

ER32 Internal Coolant collets are precision tool holders designed for sealed, coolant-through machining applications. Unlike standard collets, these sealed collets are made to an exact size with no collapse range, ensuring a tight and direct fit for maximum efficiency. Each collet is pressure-tested to withstand up to 1000 psi, making them ideal for demanding environments where coolant needs to be delivered through the tool. Manufactured to high precision standards, they help maintain excellent concentricity while supporting optimal cooling and chip evacuation during machining.
