Black oxide finish resists wear, fits perfectly in my drill, and handles a variety of materials with ease. Great for any DIY or professional project. 🛠️ ### ⭐⭐⭐⭐⭐ Good general use drill bits *by M***E on April 25, 2023* This is my second set of these black oxide Milwaukee drill bits, and I am still satisfied, and pleased with their performance, and quality. My original set lasted me 12+ years of home use, and I still have that set. I only replaced it, because I’ve damaged some of the drill bits by misuse (my fault 100%), and I lost one of the bits (I still use my old set as a beater/ sacrificial set now). I could’ve gotten a more expensive set, but these have held up so well for me that I don’t feel that it was necessary to spend more. I’ve used these for home stuff/ projects only, which involves drilling into thin metal, plastic, and wood, and I have no complaints about their performance; I am not sure how these would hold up in heavy-duty, daily professional use, but from my experience, I would recommend these if your needs are similar to mine. ## Frequently Bought Together - Milwaukee 48-89-2801 21-Piece Thunderbolt Black Oxide Drill Bit Set - 48-32-4023 Shockwave Impact Duty Steel Driver Bit Set (45-Piece) - Milwaukee 48-22-7314 CHEATER Adaptable Pipe Wrench --- ## 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.pl/products/103799449-48-89-2801-21-piece-thunderbolt-black-oxide-drill-bit](https://www.desertcart.pl/products/103799449-48-89-2801-21-piece-thunderbolt-black-oxide-drill-bit) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
