The Nikken Center Coolant Straight Collet is designed for modern CNC machining where coolant-through functionality is critical. Precision-machined to ensure concentricity and high clamping force, it supports internal coolant flow directly through the tool, optimizing heat dissipation and chip removal. Manufactured in Japan using hardened alloy tool steel, this collet ensures enhanced tool life, superior surface finish, and excellent performance at high spindle speeds. Compatible with Nikken’s milling chucks and holders, it’s a trusted solution for applications where coolant efficiency is as important as grip precision.
