Product Description
CMT Precision Collet EOC-25 - 20mm Diameter (DIN 6388) is a high-accuracy clamping collet engineered for CNC routers, machining centers, and point-to-point machines that demand tight tolerances and consistent tool positioning. Conforming to the DIN 6388 standard, this 20mm collet secures router bits and CNC tooling with the precision required for demanding milling, boring, and routing operations across a wide range of materials - from hardwood and softwood to MDF, plywood, composites, and aluminum. Where tooling accuracy directly affects cut quality and surface finish, this CMT collet delivers the reliability that production environments require.
Key Features
- EOC-25 Collet System conforming to DIN 6388 standard - ensures interchangeability and dimensional consistency across compatible toolholders, reducing setup time and guesswork on the shop floor.
- 20mm bore diameter - precisely matches 20mm shank tooling for a secure, centered grip that minimizes runout and protects both the tool and the workpiece.
- Precision ground construction - delivers the tight tolerances required for accurate, repeatable cuts in CNC routing, milling, and boring applications.
- Special dimensions available on request - provides flexibility for non-standard tooling setups without compromising the precision engineering behind the standard collet range.
Why This Product
- For CNC operations where tool runout directly affects part quality, a DIN 6388 precision collet in the correct diameter is the foundational choice - this 20mm collet meets that standard for consistent, accurate performance.
- The EOC-25 collet system is widely used across CNC routers, machining centers, and point-to-point machines, making this collet a practical fit for multi-machine shops that need a reliable, standardized clamping solution.
- Compatibility with a broad range of materials - including hardwood, softwood, MDF, plywood, composite, and aluminum - means this collet supports versatile production environments without needing to change toolholding systems.
- Precision-ground to DIN 6388 specification, this collet is a direct replacement solution for worn or damaged collets, restoring toolholding accuracy without requiring a full toolholder replacement.
