Long Series Shank Drills

About

Long Series Shank Drills Long Series Shank Drills are extra‑long twist drills made from high‑speed steel (HSS), featuring extended flutes and overall length for drilling deeper holes than standard jobber bits. They are ideal for metalworking, fabrication, mold work, and maintenance tasks — especially when you need to reach deep or hard‑to‑access areas in steel, cast iron, aluminum, or alloy materials. Their long‑length design reduces the need for multiple drill passes, offering efficiency and depth capability for demanding industrial jobs .
