Conquer tough materials with this 13-piece cobalt carbide drill bit set, engineered from M35 high-speed steel for superior heat resistance and extended lifespan. The 5% cobalt alloy composition allows these bits to maintain their cutting edge at high temperatures, delivering faster, cleaner drilling in hardened steel and iron with reduced friction and wear. Features and Benefits
- M35 High-Speed Steel with 5% Cobalt - Provides exceptional heat resistance and hardness, preventing premature dulling and allowing for higher drilling speeds in tough metals.
- 135-Degree Split Point Tip - Ensures precise starting without walking or skidding, increasing accuracy and reducing the need for center punching.
- Spiral Flute Design - Efficiently channels metal chips and debris away from the hole, preventing clogging and ensuring smoother, faster penetration.
- Straight Shank Design - Offers maximum compatibility with all standard drill chucks, including keyless models, for a secure, non-slip grip.
- 13-Piece Size Range (1/16" to 1/4") - Covers the most common drill bit sizes for a wide variety of tasks, from fine detail work to larger hole creation.
- Black Oxide Finish - Adds a layer of corrosion resistance and reduces friction for cooler operation and longer tool life. Applications
- Metal Fabrication and Repair - Ideal for drilling through stainless steel, cast iron, and other hardened alloys in automotive, machinery, or metalworking projects.
- General Construction and DIY - A reliable choice for drilling into steel framing, brackets, pipes, and other structural metal components around the home or workshop.
- Woodworking with Embedded Metal - Perfect for projects where you may encounter nails, screws, or other metal fasteners within wood, as the bits will power through without damage.

Q: What are the exact sizes included in this 13-piece cobalt carbide drill bit set? A: This set includes a comprehensive range of sizes for versatile use. While the exact sizes are not listed in the provided specifications, a 13-piece set typically covers common diameters from small pilot holes to larger clearance holes for metal and wood.. Q: How durable are these M35 high-speed steel spiral drill bits for drilling into hard metals? A: These drill bits are made from M35 cobalt high-speed steel, which is significantly more heat-resistant and durable than standard HSS. The 5% cobalt content allows them to maintain their hardness and cutting edge when drilling tough materials like steel and iron.. Q: Can I use these straight handle twist drill bits with a standard cordless drill? A: Yes, absolutely. These straight shank (round shank) drill bits are designed for universal compatibility with any standard drill chuck, including cordless drills, drill presses, and impact drivers. They are ideal for metal, steel, iron, and wood.. Q: Does this M35 drill bit set come with any warranty or guarantee? A: Warranty information is not specified for this product. We recommend checking the product listing or contacting the seller directly for details on any manufacturer's guarantee or return policy that may apply.. Q: Is this 13-piece cobalt drill bit set a good value compared to individual bits? A: Yes, this offers excellent value for DIY enthusiasts and professionals seeking quality without premium brand pricing. The 13-piece M35 cobalt set delivers reliable performance for regular use across multiple materials at a fraction of the cost of buying bits individually..
