Product Description
The CMT 183-ISO Universal Assembly Support for ISO30 Chucks is a precision-engineered chuck assembly tool designed to protect tool tapers and simplify the installation of ISO30 toolholding systems. Featuring bi-directional roller bearings that securely clamp the chuck flange during assembly, this support device eliminates the risk of taper damage that can occur when handling SK30 and related collet chuck systems. With a 50mm flange diameter and broad compatibility across multiple taper standards, it is the go-to assembly aid for machinists and toolroom technicians working with ISO30 and related chuck configurations.
Key Features
- Bi-Directional Roller Bearings - clamp the chuck flange securely from both directions during assembly, protecting the precision taper surfaces from damage and ensuring a repeatable, safe installation every time.
- 50mm Flange Diameter - sized to match the standard flange dimension on ISO30 chucks, providing a firm, accurate seating surface that eliminates play or misalignment during the assembly process.
- Universal Taper Compatibility - ISO30, DIN 2080, SK30 DIN 69871, HSK50, and Capto C5 - one tool supports a wide range of chuck taper standards, reducing the number of specialty assembly fixtures needed in a shop environment.
- Designed for ISO30 Chuck Systems - purpose-built for ISO30 and DIN 2080 chuck assembly, making it a natural fit for toolrooms equipped with smaller-format CNC spindles and manual machining centers that use this taper standard.
Why This Product
- If your toolroom handles multiple chuck taper standards - including ISO30, SK30 DIN 69871, HSK50, and Capto C5 - this single assembly support replaces the need for separate fixtures for each standard, streamlining your setup process.
- The bi-directional roller bearing design means the chuck flange is held securely regardless of the direction of torque applied during tightening, reducing operator effort and the chance of tool slippage or taper scoring.
- At a 50mm flange diameter, this support is correctly sized for the ISO30 chuck family, so you get a proper mechanical fit rather than improvising with an ill-fitting fixture that could mar precision surfaces.
- Produced by CMT, a brand recognized for precision router and cutting tool accessories, this assembly support reflects the same dimensional accuracy expected from professional toolholding equipment.

Frequently Asked Questions
Which taper standards is the CMT 183-ISO compatible with?
The 183-ISO is compatible with ISO30, DIN 2080, SK30 DIN 69871, HSK50, and Capto C5 tapers. It also supports assembly of HSK-63F, BT40, ISO40 DIN 2080, SK40 DIN 69871, and CAPTO C6 chuck systems.
What is the flange diameter of this assembly support?
The flange diameter is 50mm, matched to the standard flange dimension of ISO30 chuck systems.
How do the roller bearings on this tool protect the chuck during assembly?
The bi-directional roller bearings clamp the chuck flange securely during installation, distributing force evenly and preventing contact with or scoring of the precision taper surfaces on the chuck body.
Are there any chucks that the 183-ISO is NOT compatible with?
Yes - the 183-ISO is not compatible with chucks 183.250 and 183.251. For all other supported ISO30 and related taper configurations listed in the specifications, the tool is designed to work as intended.
