I was dismayed to see on the cover a list of metals on which I should NOT use these drills, some of which look like very popular metals I may need to drill. Moreso since I lack the expertise needed to distinguish the "bad" types of steel from any other types of steel. Though, for the price, paying for any mistakes I may make will not be tragic ## Frequently Bought Together - amoolo 1/4" Cobalt Drill Bit (10 Pcs), M35 HSS Metal Drill Bits 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 - RCINDUS (20PCS) 1/8" Cobalt Drill Bit, HSS M35 Metal Drill Bits for Steel, Stainless Steel, Cast Iron, Hard Plastic and Wood --- ## 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.vn/products/179827194-amoolo-1-4-cobalt-drill-bit-10-pcs](https://www.desertcart.vn/products/179827194-amoolo-1-4-cobalt-drill-bit-10-pcs) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-08-25*
