Straight Shank Drill Bits 

Our carbide-tipped drill bits are premium quality, professional-grade tools manufactured in Germany to the highest industry standards for Simpson Strong-Tie. They are designed to meet precise tolerance requirements and incorporate proprietary features that enhance durability and drilling speed, while improving ease of use.

Key Features

  • Uniformly brazed carbide inserts result in longer bit life
  • Most bits contain a centering tip that facilitates easy spot drilling
  • Chromium-nickel-molybdenum steel alloy body ensures hammering quality and extended service life
  • Heat-treatment procedures and shot-peened finish increase surface hardness, drilling speed, reduces drill bit wear and improves resistance to bending forces
  • Drill bits conform to ANSI Standard B212.15
