3/8" ER32 External Coolant Collet

• Coolant-Through Capability: Directs fluid around or through the tool for enhanced cooling.
• High Precision Fit: Engineered for tight concentricity and stable clamping.
• Improved Tool Life: Helps reduce heat buildup and extend cutting tool performance.
• ER32 Dimensions: Compatible with standard ER32 collet chucks (33 mm diameter, 40 mm length).
• Versatile Use: Suitable for milling, drilling, and other coolant-assisted machining operations.

ER32 External Coolant collets are precision-engineered for use in coolant-through machining applications, allowing fluid to be directed around or through the tool for improved cooling and chip evacuation. Designed to provide a secure and stable grip, these collets support high-performance operations while helping extend tool life and improve surface finish. Manufactured to strict precision standards, they offer excellent concentricity and are compatible with standard ER32 tool holders, making them ideal for a wide range of milling, drilling, and CNC applications.
