## Description

WHAT'S INCLUDED? 1 x Set (7Pcs ER11 Spring Collet Set)

Review: Works with my CNC! - I have a TwoTrees TTC450 w/ 500 watt spindle upgrade, and I wanted a collet set that would give me "ultimate flexibility" when it comes to what bits I want to use. This has 1-7mm, and I already have 8mm, so I now literally can use ANY metric bit up to the biggest size you can stuff into an ER11 collet. They even came individually packaged, and the icing on the cake is the whole set is less than $20!!! 5 stars and what a great value.
Review: works good and 1/4 the price - for the price about a 1/4 of the price of others i got and works as good
