Product Description
The CMT ER32 Precision Collet - 5/8" (15.87mm) is a high-accuracy tool-holding collet engineered to DIN 6499 standards, designed for use with ER32 chuck systems on CNC routers, machining centers, and point-to-point machines. Built as a replaceable standard ER32 collet, it accommodates a 16mm bore diameter and fits into a broad range of tapered spindle noses, making it a versatile choice for milling, boring, and precision CNC routing across wood, composite, and aluminum workpieces.
Key Features
- DIN 6499 Precision Ground Standard - machined to tight tolerances for minimal runout, ensuring consistent tool accuracy and repeatable cuts on every pass.
- ER32 Collet System Compatibility - fits chucks 183.000, 183.100, 183.200, 183.250, 183.300, and 183.400, giving you broad cross-compatibility across an established chuck lineup without needing adapters.
- 5/8" (15.87mm) Shank Diameter - 16mm Bore - precisely sized for 5/8" shank router bits and CNC tooling, eliminating play and vibration that can degrade surface finish quality.
- Replaceable Standard ER32 Collet Design - fits most tapered spindle noses and covers collet sizes from 3mm to 20mm, reducing the need for multiple chuck bodies and lowering long-term tooling costs.
- Clamping Tolerance of 0.015mm - delivers the kind of precision grip needed for demanding machining applications where tool runout directly affects part quality.
Why This Product
- Designed to DIN 6499 standards, this collet provides the dimensional consistency that CNC operators and machining center users need to maintain tool concentricity and minimize runout across repeated setups.
- The ER32 system's wide collet range - from 3mm to 20mm - means a single chuck body can accept a broad variety of tool shanks, and this 5/8" collet fills a common shank size used across routing and milling operations in wood, composite, and aluminum work.
- Compatibility with six CMT chuck models (183.000, 183.100, 183.200, 183.250, 183.300, and 183.400) makes this collet a practical stock item for shops already running CMT toolholding systems, reducing the need to source specialty components.
- As a replaceable collet, it allows worn or damaged collets to be swapped individually rather than replacing an entire chuck assembly, which keeps maintenance costs predictable and downtime short.
