Description

Specs

  • Quantity: 12-pack
  • Diameter: #55
  • Material: HSS (High-Speed Steel)
  • Point: Split Point
  • Length: Stub
  • Series: D/AST

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.
