They worked very well. Drill at slow speed for best results on SS. The 1/8 size, extra care is needed as they are small and break if to much pressure is used Never broke any of the larger sizes ## Frequently Bought Together - amoolo 5/16" Cobalt Drill Bit(10pcs), M35 HSS Metal Drill Bit Set for Hard Metal, Stainless Steel, Cast Iron Box of 10 - 1/4-Inch Cobalt Steel M35 Jobber Length Twist Drill Bits for Hard Metal, Stainless Steel, Pack of 12 - SALI Cobalt Drill Bit Set, 5Pcs 1/2" M35 High Speed Steel Jobber Length Drill Bit Kit for Hardened Metal, Stainless Steel, Cast Iron, Wood and Plastic, with Index Storage Case --- ## 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.gr/products/604535508-amoolo-5-16-inch-cobalt-drill-bits-10pcs-m35-hss](https://www.desertcart.gr/products/604535508-amoolo-5-16-inch-cobalt-drill-bits-10pcs-m35-hss) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-07*
