Features

Split-point geometry promotes self-centering and reduces walking when starting holes in metal, improving drill alignment on the first pass.

Stub length increases rigidity, delivering more stable holes and less deflection under cutting load for small-diameter work.

HSS (High-Speed Steel) construction provides better heat resistance and edge life when drilling through steel, stainless steel, and aluminum compared to standard carbon bits.

D/AST Series designation indicates tight manufacturing tolerances for consistent performance across the 12-pack.

12-pack packaging supports quick replacement and inventory readiness on job sites or workshops.

Ideal use cases include general metal fabrication, automotive repair, and hobbyist metalworking requiring precise, repeatable small-diameter holes.
