Cylindrical shank compatible with three-jaw drill chucks.
The Cobalt Drill Bit provides long-lasting performance when drilling stainless steel. This extended lifetime results from a cobalt alloy content of 5% and fully ground HSS (high-speed steel), which provides excellent surface quality, wear resistance and heat protection. Equipped with two cutters and two flutes, chips are removed quickly to make the bit last even longer. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels.
Bosch cobalt drill bits are specially designed for drilling in hard steel. Thick web helix delivers fast material removal combined with increased durability for maximum efficiency and performance. Each bit is manufactured to exacting specifications and features a split point that starts on contact with no walking or skating, eliminating the need for a center punch.
