Drill Hulk Pack of 12 9/64-Inch Cobalt Drill Bits – M35 Jobber Length for Hard Metals

Drill Hulk 12-Pack: 9/64-Inch Cobalt Bit Set for Hard Metals

Upgrade your metalworking kit with the Drill Hulk 12-piece cobalt drill bit set. Each bit is crafted from M35 cobalt steel, designed to withstand higher heat and tougher cutting tasks. The 9/64 inch diameter is paired with a 1-3/4 inch flute length and a 2-7/8 inch overall length, delivering a practical balance of rigidity and reach for metal drilling projects across steel, alloy, and other hard materials.

What sets cobalt bits apart is their improved heat resistance and edge stability at elevated temperatures. The cobalt alloy maintains cutting performance when drilling through harder metals, helping you maintain a clean start and steady progress through multiple holes. While outcomes depend on material and technique, the design supports reliable performance in demanding metalwork scenarios.

These bits are designed for repeat sharpening. The uniform hardness throughout the bit allows you to refresh the cutting edge without compromising the tool’s integrity, extending usable life compared with some standard high-speed steel bits. The 135-degree split point helps start holes with less wandering, reducing the need for extra alignment and rework on tough metals. The straight shank design ensures compatibility with a wide range of drill chucks, making the set a straightforward addition to most workshop setups.
