The ultra-short EDC body is engineered for restricted, tight spaces.Pair this compact unibit with a right-angle drill adapter to access impossible, narrow joists and boxes. **Q: why is a spiral flute step bit better than a straight flute one for DIY projects?** A: Spiral flutes clear metal chips upwards automatically, preventing clog-induced overheating and ensuring smoother, faster cutting in aluminum and wood. **Q: Can this M35 cobalt step drill bit easily cut through 304 stainless steel without burning out?** A: YES. Crafted from premium M35 Cobalt HSS (HRC 65-67), it withstands temperatures up to 1100°F. Always use cutting oil at low RPM (under 400) on hard metals for infinite lifetime. **Q: When drilling larger holes, how does a 1/4-inch shank withstand high torque without breaking?** A: With a heavy-duty, heat-treated hex shank structure that absorbs impact. Secure fully in chuck, avoid high-impact hammering, and let the spiral flute discharge chips. **Q: Can these step bits drill clean holes in delicate materials like acrylic, fiberglass, without cracking them?** A: Yes. The spiral flute design shears materials smoothly rather than scraping, preventing splintering or cracking in plastics, acrylics, and fiberglass. Always use steady, light pressure. --- ## 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.no/products/812309724-thinkwork-m35-cobalt-spiral-flute-step-drill-bit-single-size](https://www.desertcart.no/products/812309724-thinkwork-m35-cobalt-spiral-flute-step-drill-bit-single-size) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-11-10*
