Long Lifetime - The HSS Twist Drill Bit Cobalt provides long-lasting performance when drilling stainless steel. This extended lifetime results from a cobalt alloy content of 5% and fully ground HSS (h more→igh-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. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels. It has a cylindrical shank system (…

The Dormer A147 HSS-E Cobalt High Speed Steel Drill Bit is engineered for superior performance and durability. Constructed from HSS-E cobalt, this drill bit offers enhanced heat resistance and wear pr more→otection, ensuring extended tool life even under the most demanding conditions. Featuring a 130° split point, the A147 ensures precise and rapid starts, reducing bit walking and enhancing drilling accuracy. The cobalt content provides excellent performance when drilling through hard and abrasive materials such as stainless steel, cast iron, and titanium. Its optimised geometry facilitates efficient chip evacuation, minimising heat buildup and friction for smoother, faster drilling. Features …
