    • They work great!
Style: 1/4" 15pcs
Got these for my Anolex cnc machine. They are good quality for the money and are a good fit. The sizes seem to be spot on as well.

    • Fantastic Collet Set
Style: 1/4" 15pcs
This is a great set of collets! I ordered them to upgrade my CNC machine that used a simple sleeve with set screws to secure the tool to the motor spindle. This assortment allows me to securely install an end mill or engraving bit into my machine and not worry that the set screws are not going to hold it securely. Great product and a great price and a perfect upgrade for my CNC machine. ... show more

These collets work great. It would have fantastic if the imperial measurement was also on the sticker for each collet. They do give me a variety of options.
