We Sell Square & Hexagonal 16c Collet Blocks

The machinists at Cer-Mac Inc. have used 5C Collet Blocks for over 50 years. However, when a part was larger than 1 1/8 inch diameter they found they needed a 16C Collet Block.

Since they could not find a manufacturer to supply them, it was decided to design and build our own.  The 16C Collet Block was designed to be simple to use and cost-effective.  CMW now offers a 16C Collet Block that is either square or hexagonal and can hold up to 1 5/8 inch diameter through the collet.

The block is manufactured from 4140 aircraft quality steel and utilizes a manual open / close system using a spanner wrench.  The same design is available in 17-4 stainless steel for increased environmental robustness, such as in EDM applications.

As diverse as your production goals, our user-friendly 16c square collet blocks and 16c hexagonal collet blocks open up the possibilities for your shop. Our versatile square and hex collet blocks simplify machining a range of components in less time, and can easily be relocated from one machine to another without a complex remounting process. 

With CMWTech behind every component produced, our square and hex collet blocks include transparent material sourcing, factual product information, and leading warranties on every product delivered.
