Each step is clearly marked with laser engraving and provides gradual relief, easing into cuts and reducing the need to change drill bits. Constructed from M35 high-speed steel with cobalt, these bits offer exceptional strength and durability. Balanced hardened edges and a1/4" (0.64 cm) hex shank make them compatible with both cordless drills and optimized for impact drivers. The split point tip eliminates the need for a starter pilot hole, minimizing walking on the material for a quick startup. Additionally, the titanium nitride coating lowers cooling time, extending the life of the bit for repetitive drilling through tough materials.
