Product Description
CMT Precision Collet EOC-25 - 5/16 in. (8mm) Diameter by CMT is engineered for high-accuracy tool holding in CNC routing, milling, and machining center applications. Built to the DIN 6388 standard, this 8mm collet delivers the tight tolerances that demanding woodworking and metalworking operations require - reducing runout and maintaining consistent cutting performance across hardwood, softwood, MDF, plywood, composite, and aluminum workpieces. Designed as a replaceable component for EOC-25 collet systems, it keeps CNC routers and point-to-point machines running at peak precision without the cost of replacing an entire tool holder assembly.
Key Features
- DIN 6388 precision standard - manufactured to the DIN 6388 specification, ensuring a controlled, repeatable clamping interface that minimizes tool runout and protects workpiece surface quality.
- EOC-25 collet system compatibility - designed specifically for the EOC-25 collet system, making it a direct, drop-in replacement that simplifies maintenance and reduces machine downtime.
- 5/16 in. (8mm) shank diameter - accommodates 8mm router bit and CNC tool shanks precisely, ensuring a secure grip that resists slippage during high-feed-rate passes.
- Replaceable collet design - individual collet replacement instead of full chuck replacement means lower ongoing tooling costs for production environments and job shops alike.
- Special dimensions available on request - the EOC-25 collet line can be sourced in non-standard sizes, giving fabricators and machining centers flexibility when running custom tooling setups.
Why This Product
- Meets a recognized international standard - DIN 6388 compliance means the collet is built to verified dimensional tolerances, giving machinists and CNC operators confidence in tool concentricity without having to measure and verify every replacement.
- Suited to a wide range of CNC machine types - compatible with CNC routers, machining centers, and point-to-point machines, so a single collet specification covers multiple pieces of equipment in a multi-machine shop.
- Supports high-value material processing - accurate tool holding at 8mm is critical when routing or milling hardwood, aluminum, and composite panels where deflection or runout causes scrap and rework.
- Straightforward collet-system replacement - the EOC-25 interface is a standardized platform, so sourcing a replacement collet in 8mm does not require custom fitting, machine modification, or specialized tooling knowledge.

Frequently Asked Questions
What collet system is this collet designed for?
This collet is designed for the EOC-25 collet system and is built to the DIN 6388 standard. It is a direct replacement collet for any EOC-25 compatible tool holder used on CNC routers, machining centers, and point-to-point machines.
What shank diameter does this collet accept?
This collet accepts tool shanks with a diameter of 8mm (5/16 in.), which is the bore diameter machined into the collet per the DIN 6388 specification.
What materials can be processed using tools held in this collet?
CNC tools and router bits seated in this 8mm collet can be used across a range of materials including hardwood, softwood, MDF, plywood, composite panels, and aluminum.
Are other sizes available in the EOC-25 precision collet series?
Yes. Special dimensions beyond the standard 8mm (5/16 in.) size are available on request within the EOC-25 precision collet line, allowing fabricators to match collets to non-standard tool shank diameters when needed.
