They are well machined, and easy to use. I love them : ) ### ⭐⭐⭐⭐⭐ Runout is minimal. *by J***N on June 4, 2026* Great product. One problem was I received 2 7/16" collects, but no 11/32" collet. ### ⭐⭐⭐⭐ Excellent bang for the buck *by D***C on March 14, 2025* Fantastic collet set. First day I had them I used at least three different collets. I would give 5 stars but, one of them had a couple of pieces of metal chips inside from the slot cutting. I could not hesitate to buy them again, just know you'll want to check each one before the first use to make sure any metal chips do not interfere with the closer. I used the 3/8 to tram the head on a new mill. I then used the 1/4" to hold a indicator to square up my new vise and to mill the vise keys to fit my slots. I then use the 1/8 to mill a slot in a part. The results were perfection. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/69971732-14pcs-er20-spring-collet-set-for-cnc-engraving-machine](https://www.desertcart.gr/products/69971732-14pcs-er20-spring-collet-set-for-cnc-engraving-machine) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-24*
