M35 Cobalt Drill Bit Set – High-Speed Steel Jobber Length Twist Drill Kit for Hardened Metal, Stainless Steel, Iron, Wood & Plastic

Power through tough materials with precision using the Cobalt Drill Bits Set M35 High Speed Steel Twist Jobber Length—a professional-grade drilling solution built for hardened metal, stainless steel, cast iron, wood, and plastic. Whether you're a DIY builder or a workshop pro, this set is designed to deliver clean, accurate, and effortless drilling every time.

Engineered from enhanced M35 cobalt high-speed steel (5% cobalt), these drill bits offer superior strength, heat resistance, and wear durability compared to standard HSS bits. That means longer tool life, sharper cutting edges, and reliable performance even when drilling into the hardest metals.

Each bit features a precision-ground finish for smooth, clean surfaces and improved drilling accuracy. The universal round shank design ensures compatibility with most drill chucks and tool-holding systems, providing strong grip and stability during use.

The 135° split point tip is designed for fast, self-centering cuts—reducing walking, improving control, and making penetration easier even on tough surfaces. Combined with a smart twist flute design, these bits offer faster chip removal, reducing heat buildup and keeping your work smooth and efficient.

Available in 13, 21, or 29-piece sets, this collection covers a wide range of sizes, giving you the flexibility to handle everything from delicate precision tasks to heavy-duty industrial drilling.
