Product Description
CMT ER32 Precision Collet - 5/16" (8mm) 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. Whether you are running hardwood, softwood, MDF, plywood, composite panels, or aluminum, this replaceable ER32 collet delivers consistent clamping performance and minimal runout for demanding routing, milling, and boring applications.
Key Features
- ER32 precision collet system conforming to DIN 6499 standard - ensures tight dimensional tolerances and repeatable tool positioning, reducing setup time and improving cut quality across production runs.
- 5/16" (8mm) bore diameter - accepts 8mm shank tools directly, giving a secure and stable grip on a widely used shank size in CNC routing and milling operations.
- Compatible with chucks 183.000, 183.100, 183.200, 183.250, 183.300, and 183.400 - integrates seamlessly into the CMT ER32 chuck family, making it a straightforward replacement or expansion for existing setups.
- Fits most tapered spindle noses - provides broad machine compatibility beyond CMT's own chuck line, so the same collet can be used across multiple machines in a shop environment.
- Replaceable standard ER32 collet design (range: 3mm to 20mm) - allows individual collets to be swapped out as needed rather than replacing the entire chuck assembly, reducing tooling costs over time.
- Precision ground construction - minimizes runout and vibration during cutting, which directly translates to cleaner edges, tighter tolerances, and extended tool life.
Why This Product
- The DIN 6499 precision standard means this collet is machined to exacting specifications - critical for CNC routing and milling applications where even small amounts of runout can affect part accuracy and surface finish.
- With compatibility spanning six CMT ER32 chuck models as well as most tapered spindle noses, this collet is a practical choice for multi-machine shops looking to standardize their 8mm tool-holding solution.
- The replaceable collet design within the ER32 system (covering 3mm to 20mm) means you can build a complete range of shank sizes around a single chuck platform, simplifying inventory and reducing overall tooling expenditure.
- Suitability across a wide range of materials - from hardwood and softwood to aluminum and composite - makes this collet a versatile holding solution for shops that run varied workloads on CNC routers and machining centers.

Frequently Asked Questions
Which CMT chuck models is this ER32 collet compatible with?
This collet is compatible with CMT ER32 chuck models 183.000, 183.100, 183.200, 183.250, 183.300, and 183.400. It also fits most tapered spindle noses, making it suitable for a broad range of CNC routing and machining equipment beyond CMT's own chuck line.
What is the clamping tolerance of the CMT 184.080.00 ER32 collet?
The CMT 184.080.00 ER32 precision collet is manufactured to a clamping tolerance of 0.015mm, in accordance with DIN 6499 standards. This tight tolerance supports accurate, low-runout tool holding for precision CNC routing and milling work.
Can this collet be used with tools other than 8mm shank diameter?
This specific collet is sized for a 5/16" (8mm) shank diameter. However, the ER32 collet system supports a range from 3mm to 20mm, so additional collets in other sizes can be used within the same ER32 chuck to accommodate different shank diameters.
Is the CMT 184.080.00 collet a replaceable component?
Yes. This is a replaceable standard ER32 collet. Individual collets within the ER32 system can be swapped out independently of the chuck body, allowing you to replace a worn collet or add a new shank size without purchasing an entirely new chuck assembly.
