This heavy duty HSS drill bit set is engineered for the demanding environments of industrial workshops, automotive repair facilities and metal fabrication shops. Every bit is manufactured from M2 high speed steel with a hardened structure of HRC 64-66, providing the strength and edge retention needed for continuous drilling in tough materials. The set covers metric sizes from 1.0 mm to 13.0 mm, offering a complete range for structural work, equipment maintenance and production tasks.
The 135-degree split point geometry ensures immediate centering on metal surfaces, while the heavy duty flute design provides the rigidity and chip clearance required for aggressive feeds. Whether used in hand drills, pillar drills or magnetic drilling machines, these bits maintain straight, accurate holes and resist premature failure under heavy loads. For operations that depend on reliable tooling day after day, this set is built to perform.

In industrial workshops, this set handles drilling tasks on structural steel, machine frames, jigs and fixtures. Automotive repair shops use these bits for drilling out broken fasteners, preparing mounting points and modifying chassis components, where the combination of hardness and split point accuracy prevents walk-off on curved or hardened surfaces. Fabrication shops rely on the set for sheet metal, plate steel and aluminum work that demands clean holes and dependable tool life.
The heavy duty design also supports maintenance crews drilling into machinery bases, conveyor systems and plant equipment. With the correct speeds and lubrication, these bits deliver consistent results across carbon steel, alloy steel and stainless steel, making them a staple tool in any serious metalworking environment.
