The cobalt drill bits of the DT49 series from DeWalt are designed for effective 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 up to 1100N/mm². The tip protrudes to produce an easier initial drilling, for more precise and clean-cut holes. The shaft is slightly triangular, allowing it to grip more firmly in the jaws of the chuck, without slipping. The core has increased strength to prevent breaking or bending. Suitable for use with drill drivers and fixed drills.
