I clamoed them on the mill and measured with a tenths indicator. There were pretty much flat and parallel for their dimensions.I would give them five stars but the clamping nut included is too narrow. It works but variable spanners (the type with a pivot bolt between the spanner pins) get hung up on the block body. The pivot point of the spanner hits the block body.If the nut were .125 thou wider on each side (.250 overall) this probably would not happen.It's not a huge issue but does cause a slowdown and frustration when changing collects mid run. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Don’t expect a wood box *by K***R on Reviewed in the United States on August 9, 2019* Took off one star because it didn’t come in a wood box. Otherwise fit and finish OK ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars nice set *by R***E on Reviewed in the United States on February 12, 2019* plastic case doesn't look like it will last very long. Wish the set came with a spanner wrench . fit and finish is good. should do me a great job --- ## 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.co.uk/products/65022685-yonntech-5c-cb-5c-collet-block-set-hex-collet-block](https://www.desertcart.co.uk/products/65022685-yonntech-5c-cb-5c-collet-block-set-hex-collet-block) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-15*
