Product Description
CMT 184.192.00 ER40 Precision Collet - 3/4" (19mm) Diameter by CMT is a high-accuracy tool holding collet engineered to DIN 6499 standards, designed for secure gripping of 3/4" (19mm) shank router bits and cutting tools in CNC routers, machining centers, and point-to-point machines. Whether you are running production milling, boring operations, or precision CNC routing through hardwood, softwood, MDF, plywood, composite materials, or aluminum, this ER40 collet delivers the repeatable clamping force and minimal runout that demanding machining applications require.
Key Features
- DIN 6499 precision ground standard - machined to tight tolerances for minimal runout, meaning your router bits and CNC tooling stay accurately centered during every pass, reducing waste and improving cut quality.
- ER40 collet system compatibility - fits most tapered spindle noses and is interchangeable with other standard ER40 chucks, giving you flexibility across multiple machines without purchasing dedicated tooling for each.
- 3/4" (19mm) bore diameter - accepts standard 19mm shank tooling directly, providing a solid, vibration-damping grip that helps extend tool life and maintain surface finish quality.
- Compatible with CMT chucks 183.201, 183.211, 183.221, and 183.310 - integrates seamlessly into the CMT chuck system, so you can build out a matched tool holding setup with confidence in fit and performance.
- Replaceable design - collets are individually replaceable within your existing chuck, lowering the cost of maintaining a full set of accurate tool holders over time rather than replacing entire assemblies.
- ER40 system clamping range from 3mm to 25mm - the broader ER40 chuck system supports a wide variety of shank sizes, making this collet part of a versatile, scalable tool holding solution.
Why This Product
- For CNC router and machining center operators who need consistent, repeatable tool positioning, the DIN 6499 precision ground construction keeps runout to a minimum - directly translating to cleaner cuts, tighter tolerances, and less rework on hardwood, MDF, plywood, composite, and aluminum workpieces.
- The ER40 standard is widely adopted across CNC routing and milling equipment, meaning this collet fits most tapered spindle noses - reducing compatibility concerns when moving tooling between machines or upgrading equipment.
- As a replaceable collet rather than a fixed chuck assembly, this component lets you maintain precision tool holding at a lower cost - simply swap a worn collet instead of replacing an entire chuck unit.
- Rated for a clamping tolerance of 0.015mm, this collet provides the dimensional control that separates production-quality machining from general-purpose cutting - making it a practical choice for shops running repetitive CNC routing, boring, or milling cycles.

Frequently Asked Questions
Which CMT chucks is this ER40 collet compatible with?
This collet is designed for use with CMT chuck models 183.201, 183.211, 183.221, and 183.310. It also fits most other tapered spindle noses that accept the standard ER40 collet format.
What shank diameter does this collet accept?
This collet is sized for a 3/4" (19mm) shank diameter. The broader ER40 system supports replaceable collets ranging from 3mm to 25mm, so additional sizes are available within the same chuck for other tooling needs.
What does DIN 6499 mean for my machining results?
DIN 6499 is a precision manufacturing standard that governs the dimensional accuracy and clamping tolerances of ER-style collets. Conforming to this standard ensures a clamping tolerance of 0.015mm, which minimizes tool runout and helps maintain consistent cut accuracy across CNC routing, boring, and milling operations.
What materials can I machine using tools held in this collet?
This ER40 collet is suited for machining hardwood, softwood, MDF, plywood, composite materials, and aluminum when used in compatible CNC routers, machining centers, and point-to-point machines.
