ER Type Collets

A wide selection of metric and imperial ER type standard collets. These are suitable for use with several spindles including Perske, Elte, Colombo and HSD.

It is essential to use the correct size collet for the tool shank diameter. First make sure you are looking at the right type of collet to fit the spindle on your machine and then select the required size from either the metric or imperial range.

Use the table below to select the right size of ER collet. The example spindles shown are just a small selection of where these collets can be used. Even if your spindle is listed the best way to check compatibility is to compare the dimensions in the table with one of your existing collets.
