Quick Change ER Collet Adaptors

Quick Change collet adaptors make it easier to control quality in your shop. These adaptors make it simple to have preset tooling available, eliminating the need to touch off the tool after a routine change. This also enables less experienced machine operators to be more productive.

Each Quick Change ER Collet Adaptor Includes the following components:

  • Quick Change ER adaptor
  • "Middle nut" for affixing the adaptor to your ER collet holder
  • ER Collet with ID of your choice
  • "ER" clamping nut

Works with ANY ER tool holding system and retains TIR of less than .001"
