The cobalt drill bits of the DT49 series from DeWalt are designed for efficient drilling tasks in metals and other structural materials.

They are made from high-speed steel (HSS) alloy with a 5% cobalt blend. They can even drill stainless steel, as they withstand mechanical stress of up to 1100N/mm². The tip protrudes, making initial drilling easier for more accurate and well-cut holes. The shaft is slightly triangular, allowing for a firmer grip in the chuck jaws without slipping. The core has increased strength to prevent breaking or bending. Suitable for use with drills and stationary drill presses.
