Probably both. Got every bit of 1/2 of an inch across some particle board at about an 1/8 of an inch deep and snapped just about right at the base where the bit meets the shank. There are certainly better, stronger bits for detail work. --- ## 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.vu/products/420665102-xuanfeng-stf-435-upcut-spiral-cnc-router-bit-4-flutes](https://www.desertcart.vu/products/420665102-xuanfeng-stf-435-upcut-spiral-cnc-router-bit-4-flutes) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-18*
