Product Description
The CMT ER32 Precision Collet - 3/8 in. (9.5mm) is a high-accuracy toolholding component engineered to DIN 6499 standards, designed for use with ER32 chuck systems on CNC routers, machining centers, and point-to-point machines. Built for professional woodworking and light metalworking applications, this precision collet delivers consistent clamping performance for 3/8 in. shank router bits and CNC tooling - minimizing runout and maximizing cut quality across a wide range of materials. Whether you are running production milling operations or precision boring work, this ER32 collet provides the reliable toolholding accuracy that demanding machining environments require.
Key Features
- DIN 6499 precision ground construction - meets the internationally recognized standard for ER collets, ensuring minimal runout and repeatable tool positioning for accurate cuts every time.
- ER32 collet system compatibility - fits CMT chucks 183.000, 183.100, 183.200, 183.250, 183.300, and 183.400, as well as most tapered spindle noses that accept standard ER32 toolholding collets.
- 3/8 in. (9.5mm) bore diameter - precisely sized for 3/8 in. shank router bits and CNC tools, providing a secure grip that reduces vibration and extends tool life.
- Replaceable standard ER32 collet design - swappable with other standard ER32 collets ranging from 3mm to 20mm, giving you the flexibility to use a single chuck with multiple tool shank sizes.
Why This Product
- Precision machined to DIN 6499 tolerances, this ER32 collet reduces tool runout - which directly translates to cleaner cuts, longer tool life, and more consistent results in CNC routing and milling operations.
- The standard ER32 format means this collet is interchangeable across a wide range of compatible chuck systems and tapered spindle noses, making it a versatile addition to any CNC or machining center setup.
- With a bore diameter of 9.52mm and compatibility across an ER32 collet range of 3mm to 20mm, this toolholding solution supports a broad variety of router bits and CNC cutting tools from a single chuck platform.
- Designed for use with hardwood, softwood, MDF, plywood, composite materials, and aluminum, this collet supports the full range of materials commonly processed on CNC routers and machining centers.

Frequently Asked Questions
Which CMT chucks are compatible with this ER32 precision collet?
This collet is designed for use with CMT chucks 183.000, 183.100, 183.200, 183.250, 183.300, and 183.400. It also fits most tapered spindle noses that accept standard ER32 collets.
What shank diameter does this collet accept?
This collet is sized for a 3/8 in. (9.5mm) tool shank, with a precision bore diameter of 9.52mm to ensure a secure, accurate fit for compatible router bits and CNC tooling.
Can this collet be used with non-CMT ER32 chuck systems?
Yes. As a standard ER32 format collet built to DIN 6499, it fits most tapered spindle noses and chuck systems designed to accept ER32 replaceable collets - not just CMT-branded chucks.
What is the full clamping range available in the ER32 collet system?
The ER32 system supports replaceable standard collets covering tool shank diameters from 3mm to 20mm, allowing a single ER32 chuck to accommodate a wide variety of router bits and CNC cutting tools by swapping collets.
