ER11 Spring Collet Set φ1, 2, 3, 4, 5, 6, 7mm

Premium Collet Set excellent quality

I bought the Collet set to go with my Sainsmart 3018 CNC machine, the collets snap perfectly into the collet clamping nut and now I can use the vast range of cutters & milling bits available from Sainsmart. The collets have certainly been manufactured to a high precision and in use I have experienced no issues like bit wobble or unwanted vibration so they work great at high speeds. They are a great addition to my CNC and I can recommend them to other users. Thanks Sainsmart from Andy...

Great product delivered as promised

Each collet was in its own container. Each container had the collet size marked. Was easy to store them for use.
