WOW! *by A***R on November 14, 2022* This is the go to Drill Bit! WOW! 42 Bucks at Lowe's and All 3 of the Name Brand Bits BURNED UP!!! These went right through the Stainless Steel in seconds!!! I so am going to do a YOUTUBE.COM video to show this! The BiG Name Brands owe me some money!! What happened to truth in advertising? These are TOP CLASS!!! Buy em' and don't look back~! ### ⭐⭐⭐⭐⭐ Used to drill out grade 8 bolts in a bulldozer track *by T***C on December 7, 2019* They are sharp and true. They do have cobalt in the metal which makes them prone to the cutting edge breaking when bound against the last part of the cut. If you are using is a hand drill expect this. I was able to drill though track bolts (grade 8) on the master link. If I kept a close watch on the amount of pressure i was putting on the bit I had no problem with the cutting edge breaking. I never broke a bit except the cutting edge which was my fault,Overall great bit especially for the price. ### ⭐⭐⭐⭐⭐ Just Keeps on Working *by M***R on April 29, 2021* I got these for drilling holes to install self-tapping screws for the rebuild of my trailer deck. I drilled thru 1.5 inches of wood and about 1/4 inch of metal framing for each screw. I needed to put in 60 screws and I figured I would run through 5 or 6 drill bits to complete the job. Well I put in all 60 screws and made a few other holes in heavy metal and I am still on my first drill bit! ## Frequently Bought Together - BEILI TOOLS HSS M35 Cobalt Twist Drill Bits, Pack of 10 (3.2mm, 1/8") - 1/16-Inch Cobalt Steel M35 Jobber Length Twist Drill Bits for Hard Metal, Stainless Steel, Pack of 12 - DelitonGude 17/64" inch HSS M35 Cobalt Twist Drill Bit,High Speed Steel,Pack of 5,Suitable for Steels,Cast Iron,Stainless Steel,Copper and Other Hard Metals（17/64inch） --- ## 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.tn/products/90931765-beilitools-hss-m35-cobalt-twist-drill-bits-pack-of-10](https://www.desertcart.tn/products/90931765-beilitools-hss-m35-cobalt-twist-drill-bits-pack-of-10) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-12*
