Collet Measuring Guide
The easiest way to determine what type of collet your machine has is to measure the length and diameter of the collet. All collets have a distinctive length and diameter. Use the chart below to determine the correct collet series for your machine.

Using the right size collection for your tool shank diameter is crucial. First, make sure that you look at the correct sort of collet to fit your machine’s spindle. A common error is the attempt to fit a shank tool, that’s too large, into a smaller collet. It’ll go in and you’ll be able to tighten it, but the collet will be stressed.
