Product Description
CMT ER32 Precision Collet - 3/4" (19mm) Bore Diameter by CMT 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. This replaceable collet accepts 3/4" (19mm) shank tooling and delivers the tight tolerances required for precision milling, CNC routing, and boring operations across a broad range of materials.
Key Features
- ER32 Collet System, DIN 6499 Precision Ground - machined to the internationally recognized DIN 6499 standard, this collet delivers minimal runout and repeatable tool accuracy, which is critical for fine CNC routing and milling work where dimensional consistency matters.
- 3/4" (19mm) Bore Diameter - accepts standard 3/4" shank router bits and cutting tools, making it a direct, reliable fit for the most common large-shank tooling used in production and professional CNC environments.
- Compatible with CMT Chucks 183.000, 183.100, 183.200, 183.250, 183.300, and 183.400 - works within a specific, verified range of CMT ER32 chuck bodies so you can expand or replace collets without changing your entire chuck setup.
- Fits Most Tapered Spindle Noses - the standard ER32 profile is widely adopted across CNC platforms, meaning this collet integrates with a broad range of machine spindles beyond the CMT ecosystem, maximizing the value of your investment.
- Replaceable Standard ER32 Collet - because collets wear over time with repeated clamping cycles, this design allows individual replacement rather than replacing the entire chuck assembly, reducing long-term tooling costs.
- Clamping Range from 3mm to 20mm - the ER32 system accommodates a wide variety of shank diameters within a single chuck, reducing the number of different collets needed and streamlining tool changes during production runs.
Why This Product
- Built for high-precision CNC applications - the DIN 6499 specification ensures this collet meets the dimensional and runout tolerances demanded by CNC routing, milling, and boring operations where tool position accuracy directly affects cut quality.
- Broad machine compatibility - the ER32 collet standard is one of the most widely used tool holding formats in CNC machining, meaning this collet works across CNC routers, machining centers, and point-to-point machines without adapter hardware.
- Individual replaceability keeps costs down - instead of replacing an entire chuck assembly when a collet wears, this standard ER32 collet can be swapped out independently, making it a cost-effective maintenance solution for busy shops.
- Handles a wide material range - suitable for use with hardwood, softwood, MDF, plywood, composite materials, and aluminum, making it a versatile collet for shops that process multiple material types on the same CNC platform.

Frequently Asked Questions
Which CMT chuck bodies is this collet compatible with?
This ER32 precision collet is designed for use with CMT chuck models 183.000, 183.100, 183.200, 183.250, 183.300, and 183.400. It also fits most tapered spindle noses that accept the standard ER32 collet format.
What is the clamping range of this ER32 collet?
The ER32 system accepts shanks from 3mm to 20mm in diameter. This specific collet is sized for 3/4" (19mm) shank tooling and delivers a clamping tolerance of 0.015mm for precise, secure tool holding.
What types of materials can I machine using this collet and compatible tooling?
This collet supports operations on hardwood, softwood, MDF, plywood, composite materials, and aluminum, making it suitable for a wide range of woodworking and light metalworking CNC applications.
Is this a replacement collet or does it come with a chuck body?
This is a replaceable standard ER32 precision collet only - it does not include a chuck body. It is intended to replace a worn or damaged collet within an existing compatible ER32 chuck assembly.
