Review: Would highly recommend this product. - High quality products great price. Review: These eat through the metal 👌 - These drill bits are fantastic for drilling through the metal so we could put the new metal legs on our outdoor couch ## Features - COBALT STEEL - Manufactured from M35 cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, extremely heat resistant; for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit. - NO CENTER PUNCH NEEDED - The 135° Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not "walk" or "wander". Straight shank allows for firmly holding and accurate centering, fit for standard drill chucks and regular round collet chucks. Must be used and operated at proper RPMs for maximum efficiency - 13PC METRIC BITS - The set includes 13pcs of M35 cobalt steel twist drill bits: 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm, 6.5mm. Well organized in a plastic indexed storage case for easy transport to your worksite. - FOR METALWORKING - Particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too. Not for hardened steel / high carbon steel. Try to adjust the RPM when it fails to penetrate. - DOWNLOADABLE USER GUIDE - We've summed up some tips of drilling metals, including a RPM chart for several common metals, based on our reviews and some articles on the internet.

M35 grade steel with 5% Cobalt is specifically engineered for high-tensile metals like stainless steel, cast iron, and titanium alloys. For fully hardened steel (HRC > 50), carbide bits are recommended. **Q: Will these bits fit my standard cordless drill?** A: Yes. These feature standard round straight shanks. The largest diameter is 6.5mm, allowing them to fit securely into any standard 3/8-inch (10mm) or 1/2-inch (13mm) drill chuck. **Q: Do I need to use cutting oil or lubricant?** A: Highly recommended. While Cobalt is heat-resistant, using cutting fluid significantly reduces friction and heat buildup. This prevents the bit from annealing (softening) and greatly extends its lifespan. **Q: Do these bits require a center punch to start?** A: No. These bits feature a 135° Split Point tip. This design is self-centering and cuts immediately upon contact with the metal, preventing the bit from "walking" or skating across the surface. **Q: Are these bits just coated with Cobalt or solid?** A: They are solid M35 Cobalt steel throughout, not just coated. Unlike titanium-coated bits that lose effectiveness once sharpened, these maintain their heat resistance and performance even after resharpening. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Would highly recommend this product. *by D***D on 14 March 2020* High quality products great price. ### ⭐⭐⭐⭐⭐ These eat through the metal 👌 *by H***M on 30 January 2026* These drill bits are fantastic for drilling through the metal so we could put the new metal legs on our outdoor couch ### ⭐⭐⭐⭐⭐ quarter of the price and quality is great *by M***C on 13 January 2024* quarter of the price and quality is great ## Frequently Bought Together - Hymnorq 13-Piece Cobalt Drill Bit Set with Index Case – M35 Grade (5% Cobalt) Steel, 1.5mm to 6.5mm, Dual Twist Flute, 135° Split Point, Ideal for Hard Metals Like Stainless Steel and Cast Iron - Owl Tools 4.5mm Cobalt Drill Bits - 13 Pack M35 Cobalt Drill Bits with Storage Case - Perfect for Metal, Hardened & Stainless Steel, Cast Iron - M35 5% Cobalt Metric Drill Bits Set (1mm-10mm/19pcs), Straight Shank Jobber Drill Bits, Metal HSS Twist Drill Bits for Stainless Steel Hard Metal and Cast Iron --- ## 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/321471947-13-piece-cobalt-drill-bit-set-with-index-case-m35](https://www.desertcart.be/products/321471947-13-piece-cobalt-drill-bit-set-with-index-case-m35) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-17*
