- REVOLUTIONIZE DRILLING EXPERIENCE: Take your projects to the next level with this M35 Cobalt Drill Bit Set featuring a 3-Flute Design. Built for metal and steel drilling, these drill bits deliver greater efficiency, accuracy, stability, and durability—making them the first choice for professional and DIY users alike
- SPECIAL 3-FLUTE DESIGN: The 3-flute drill bit design provides three cutting edges for faster penetration and smoother operation. With a 125° split point tip, the bits stay stable, self-centering for precise and clean holes, while the three spiral flutes ensure superior chip removal and minimize clogging
- TiN COATING & M35 COBALT HSS: Made from M35 cobalt high-speed steel (with 5% cobalt), these bits achieve up to 3X longer tool life compared to standard HSS. The premium gold TiN coating makes them 5X more wear-resistant than uncoated bits, reducing friction and heat for extended performance in demanding drilling tasks
- 3-FLATS NO SPIN SHANK: Most drill bits larger than 3/16" feature a three-flat shank that mounts securely in standard chucks, minimizing spin-out. This design ensures easy installation, stable performance, and precise control, whether you use a hand drill or drill press
- 20-PIECE DRILL BIT SET WITH INDEXED CASE: This 20-piece set includes both 3-flute and 2-flute bits for versatile use. 3-Flute Sizes(12PCS): 1/2", 3/8", 5/16", 1/4", 7/32", 13/64", 3/16", 11/64", 5/32", 9/64", 1/8" (×2); 2-Flute Sizes(8PCS): 7/64" (×2), 3/32" (×2), 5/64" (×2), 1/16" (×2).
