Irwin 10502500 HSS Pro Drill Bit Set 19-Piece

This 19-piece HSS drill bit set is designed for durable metal drilling and versatility across materials. It comprises high-speed steel (HSS) bits, with oxidized tooling for enhanced long-term durability. The set features an 118° (split point in some variants) geometry to improve centering and drilling efficiency, along with precision-ground cutting edges for accurate results. Bits are sized from 1.0 mm to 10.0 mm in 0.5 mm increments and are supplied in a hardwearing metal case for organized storage. Manufactured to standards aligned with DIN 338, the bits include a cylindrical shank for easy handling and compatibility with common drill chucks. While many bits are optimized for steel and steel castings, the set is compatible with alloyed and non-alloyed steel, cast iron, non-ferrous metals, plastics, and other materials, making it suitable for drilling in metal, wood, and plastics depending on the material and bit size. These features combine to support fast, accurate drilling with reduced pilot hole requirements in appropriate applications.
