Are you tired of dull, inefficient drill bits that wear out quickly and ruin your projects? Meet the 15pc M35 Cobalt Contain Roasted Yellow Straight Shank Twist Drill Set — a professional-grade, high-performance tool kit engineered for precision, durability, and versatility. Crafted from M35 cobalt alloy high-speed steel (HSS), these drills offer superior heat resistance, hardness, and longevity compared to standard HSS bits — making them ideal for drilling through tough materials like stainless steel, cast iron, titanium alloys, and hardened plastics.
Each bit features a full ground flute design and straight shank for optimal chip evacuation, reduced friction, and smooth, accurate hole drilling from 1.5mm to 10mm. The distinctive roasted yellow titanium nitride (TiN) coating not only enhances wear resistance and reduces galling but also provides excellent visibility during use — helping you maintain alignment and control even in low-light conditions.
This comprehensive 15-piece set includes the most commonly used sizes: 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 8, 9, and 10mm — covering nearly every drilling need in metalworking, woodworking, automotive repair, DIY projects, and industrial maintenance. Whether you’re a professional machinist, hobbyist, or home workshop enthusiast, this set delivers consistent, clean results without wandering or burring.





What makes this set truly exceptional is its unbeatable value. Normally priced much higher for cobalt HSS drill sets of this quality, you can now own this complete 15-piece collection for just $10.39 — a fraction of the cost of comparable professional kits. With over 2,971 units sold and consistently positive feedback, this is a proven bestseller trusted by craftsmen worldwide.
Don’t settle for cheap, brittle bits that break under pressure. Invest in tools that last — drill after drill, project after project. Whether you’re tapping holes, creating pilot holes, or performing precision machining, this M35 cobalt set ensures reliability and performance you can count on.
