Product Description
The CMT Precision Collet EOC-25, 3/4" (19mm) Diameter is a high-accuracy tool-holding collet engineered to the DIN 6388 standard, designed for use in CNC routers, machining centers, and point-to-point machines. Built for professional woodworking and machining operations, this collet accepts 19.05mm shank diameter router bits and cutting tools, delivering the tight tolerances and consistent grip that demanding CNC applications require. Whether you are routing hardwood, milling aluminum, or working with composite panels, a precision collet at this accuracy level helps reduce runout and maintain clean, repeatable cuts across every pass.
Key Features
- EOC-25 Collet System (DIN 6388 Standard) - conforms to the internationally recognized DIN 6388 specification, ensuring dimensional compatibility with EOC-25 compatible tool holders and reliable interchangeability across machine setups.
- 3/4" (19.05mm) Bore Diameter - accepts 3/4" shank router bits and CNC cutting tools, one of the most widely used shank sizes in professional CNC machining, giving you broad tool compatibility.
- Precision Ground Construction - the collet is precision manufactured to tight tolerances, minimizing runout and helping protect both the tool shank and the workpiece from vibration-induced inaccuracies.
- Special Dimensions Available on Request - standard 19.05mm bore covers the most common 3/4" tooling, and non-standard configurations can be sourced for specialized applications, reducing the need to compromise on fit.
Why This Product
- Choosing a DIN 6388 - rated collet means your 3/4" shank tools are held to a verified dimensional standard, which directly translates to more accurate cuts and longer tool life in CNC routing and milling operations.
- The EOC-25 form factor is a widely adopted collet system in professional CNC machining centers and point-to-point machines, making this collet a straightforward, compatible replacement for worn or out-of-tolerance collets in your existing setup.
- Precision-ground bores at this tolerance level reduce micro-vibration during cuts in demanding materials like aluminum, MDF, plywood, and hardwoods - protecting your investment in both the collet and the cutting tools it holds.
- CMT manufactures this collet to a published international standard rather than a proprietary spec, which means you can verify fit and performance expectations before installation rather than relying on guesswork.

Frequently Asked Questions
What collet system does this collet use, and is it compatible with standard EOC-25 tool holders?
This collet uses the EOC-25 collet system and is manufactured to the DIN 6388 standard. It is designed to fit EOC-25 compatible tool holders found on CNC routers, machining centers, and point-to-point machines. Always confirm your machine's collet system before installing.
What shank diameter does this collet accept?
This collet accepts tool shanks with a diameter of 3/4" (19.05mm). It is intended for use with router bits and CNC cutting tools that have a 3/4" shank - one of the most common shank sizes in professional CNC tooling.
What materials can I work with using this collet and compatible 3/4" shank tooling?
This precision collet is suited for CNC routing, milling, and boring operations across a wide range of materials including hardwood, softwood, MDF, plywood, composite materials, and aluminum, provided you are using appropriate 3/4" shank cutting tools designed for those materials.
Are non-standard bore dimensions available in addition to the 3/4" (19.05mm) size?
Yes. According to CMT product data, special dimensions beyond the standard 19.05mm bore are available on request. Contact CMT directly for information on non-standard collet configurations for specialized tooling requirements.
