Any questions, please feel free to contact us by email. --BINSTAK Customer Services Team **Q: is there any manufacturer recommended speeds to use on a cnc?** A: Short answer no. I would google about speeds and feeds. The spindle speed and the feed rate go hand and hand. It also controls chip load. The faster something spins the faster it will need to move while cutting. Most tools will only have a max rpm limit. This tool I would stay away from its cheap. The carbide quality is horrible. The insert pockets are sloppy. **Q: How is the quality of this bit** A: Really great quality! Great value for money **Q: Anyone ever try using this like a drill bit into wood?...I go through 1" forsner bits like candy, and would love to be able to index the cutters** A: I tried that on the CNC but didn't go very well. Whenever the bit is going just vertically into the the wood it burns it. I imagine it is because there is no angle on the inserts and it was made to cut from the sides only. For surfacing and milling it is amazing. --- ## 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.at/products/270342109-cnc-spoilboard-surfacing-router-bit-1-4-shank-1-cutting](https://www.desertcart.at/products/270342109-cnc-spoilboard-surfacing-router-bit-1-4-shank-1-cutting) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-17*
