Product Description
CMT Precision Collet EOC-25 D 3/8" (10mm) by CMT is a high-accuracy replacement collet designed for 10mm shank diameter router bits and CNC tooling. Built to EOC-25 (DIN-6388) standards, this collet delivers the tight tolerances and consistent clamping force that CNC router operators and machining center technicians depend on for clean, repeatable cuts. Whether you are outfitting a point-to-point machine or a full machining center, this precision collet keeps 10mm shank tools locked securely and running true.
Key Features
- EOC-25 (DIN-6388) collet system - conforms to an internationally recognized standard, ensuring compatibility with EOC-25 toolholders used on CNC routers and machining centers.
- 10mm bore diameter - accepts 10mm shank router bits and CNC tools without adapter sleeves, reducing vibration risk and keeping tool runout to a minimum.
- Precision ground construction - machined to tight tolerances so the tool shank is gripped evenly along its full contact surface, producing accurate, repeatable results pass after pass.
- Replaceable design - functions as a standard drop-in replacement collet, allowing worn or damaged collets to be swapped out without replacing the entire toolholder assembly, reducing downtime and maintenance cost.
- Clamping tolerance of 0.015mm - this extremely fine tolerance minimizes tool runout, protecting both the workpiece surface quality and the router bit's cutting edges from premature wear.
Why This Product
- Purpose-built for 10mm shank tooling - the 10mm bore diameter is a direct match for 10mm shank router bits and CNC cutters, eliminating the need for reduction sleeves that can introduce play or imbalance.
- Engineered to DIN-6388 standard - the EOC-25 specification is a recognized industry benchmark, giving machine operators confidence that the collet will seat and perform correctly in compatible toolholders.
- Tight 0.015mm clamping tolerance protects your tools and workpieces - minimal runout means cleaner edge profiles, reduced chatter, and longer cutting tool life on CNC routers, machining centers, and point-to-point machines.
- Straightforward replacement part - the standard EOC-25 form factor makes this a practical maintenance item to keep on hand, so production does not stop when a collet shows wear.

Frequently Asked Questions
What collet system does this collet belong to?
This collet is part of the EOC-25 system, which conforms to the DIN-6388 standard. It is designed to seat correctly in EOC-25 compatible toolholders found on CNC routers, machining centers, and point-to-point machines.
What shank diameter does this collet accept?
The bore diameter is 10mm, so it is designed to grip 10mm shank router bits and CNC cutting tools directly, with no reduction sleeve required.
What is the clamping tolerance of this precision collet?
The clamping tolerance is 0.015mm. This tight tolerance minimizes tool runout, which helps maintain cut quality and protects cutting edges from uneven wear during CNC routing and machining operations.
Is this a replacement collet or part of a complete toolholder assembly?
This is a standalone replacement precision collet. It is designed as a replaceable component, allowing you to swap out a worn or damaged collet without replacing the entire EOC-25 toolholder assembly.
