They work great!!! Nice case and good assortment of sizes. Will buy again ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Worth the price for hobbyist *by G***E on Reviewed in the United States on January 12, 2020* I stumbled across this product while in the process of searching out individual cobalt drill bits, both indexed and individually. I will admit I was skeptical, especially given the price. I assumed the positive reviews were fake and from the seller. While this could be the case, they worked perfectly for my project, which was drilling 3/8" steel posts. While they were not hardened, one of the spots drilled was on a seam which caused me much trouble during an earlier drilling. However, these combined with Tap Magic drilled the needed holes flawlessly.I would absolutely purchase these again. I do not know how well they would work without some sort of machining oil. One of the best parts of these bits are the variety of sizes. One purchaser commented on why they would ever need so many different sizes. If you are drilling next to brackets, as I was, the slimmer steps are a necessity. The case is also extremely handy, especially given that I have so many step bits with no home currently. The case will ensure I do not damage these bits using them carelessly on another project.I do not know how well these would hold up to thousands of drillings but from looking at them following around 30, they seem sharp, both the tip and the cutting edge. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Good quality step drill bit *by A***R on Reviewed in the United States on July 12, 2019* They work good on wood aluminum and thin sheet metal. I use them on electrical control boxes. --- ## 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.com.sa/products/138891342-5pcs-hss-cobalt-titanium-step-drill-bit-set-tools-high](https://www.desertcart.com.sa/products/138891342-5pcs-hss-cobalt-titanium-step-drill-bit-set-tools-high) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-06-04*
