Feels like it's already sanded up to 100/120grit. I'm running it fairly slow at 13K rpm, 1000mm/min, 1.5mm stepover, 1mm depth of cut ### ⭐⭐⭐⭐⭐ Did the job. *by J***D on December 20, 2025* Bit was perfect for the cost. It did everything I needed it too. Cut was nice. ### ⭐⭐⭐⭐⭐ Don't drop it *by M***S on August 19, 2023* I have found my go to bit for dep carves on my cnc machine. The bits have worked well every time I have used them. The issue with longevity is really my fault and not the bit. I have plunged my router too deep and had the lower portion snap off and I have also dropped it from about 5 feet and had it snap off too. for what it costs it is a great bit. --- ## 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.be/products/345130997-spetool-down-cut-spiral-router-bit-1-16-inch-cutting](https://www.desertcart.be/products/345130997-spetool-down-cut-spiral-router-bit-1-16-inch-cutting) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-23*
