When you're working with hardened steel, stainless steel, or other tough metals, you need drill bits that can handle the challenge without breaking, bending, or losing their edge. The toolant Pro Cobalt Drill Bit Set is engineered specifically for demanding metalworking applications where precision and durability aren't just nice-to-have features—they're essential.
What sets these drill bits apart is their M35 cobalt high-speed steel construction. This isn't your ordinary drill bit material—cobalt alloy provides superior strength and heat resistance that allows the bits to maintain their cutting edge even at high temperatures. Whether you're drilling through hardened steel brackets, stainless steel fixtures, or other challenging alloys, these bits deliver consistent performance that won't quit on you halfway through a job.
Each bit in this 5-piece set is coated with titanium aluminum nitride (TiAlN), a high-performance coating that dramatically increases surface hardness to 89HRC. This coating does more than just make the bits look impressive—it provides outstanding heat resistance and reduces friction, allowing the bits to cut faster while staying sharper longer. The result? Fewer bit changes, smoother drilling, and cleaner holes in even the most difficult materials.
One of the most frustrating experiences in metalworking is when your drill bit wanders off center, especially on hard or angled surfaces. That's why toolant crafted these bits with a specialized bullet point tip design. The sharp, self-centering tip bites into the material immediately, minimizing wandering and ensuring your holes start exactly where you want them. This precision is crucial when working on projects that demand accuracy, from automotive repairs to fabrication work.
This 5-piece set gives you multiple 1/2" drill bits, so you always have a backup ready when you need it. Whether you're a professional metalworker, a mechanic, or a serious DIY enthusiast, these bits will quickly become your go-to choice for metal drilling projects. And with toolant's 90-day warranty, you can purchase with confidence knowing that if you're not completely satisfied, they'll make it right.
