The Simpson 1/8 in. x 3 in. Straight Shank Carbide-Tipped Drill Bit is a premium-quality, professional-grade tool engineered by Simpson to meet precise tolerance requirements for reliable, consistent drilling performance. Built to the highest industry standards, this carbide-tipped bit incorporates proprietary design features that enhance durability and drilling speed while improving ease of use - making it a dependable choice for demanding drilling and demolition applications where accuracy and bit longevity matter most.

Key Features

• Uniformly brazed carbide inserts - deliver consistent cutting performance and result in longer bit life, reducing the need for frequent replacements on the job.
• Centering tip design - facilitates easy spot drilling so the bit stays on target from the first contact, improving accuracy and reducing operator effort.
• Chromium-nickel-molybdenum steel alloy body - ensures hammering quality and extended service life, standing up to the rigors of heavy-duty professional use.
• Heat-treatment procedures and shot-peened finish - increase surface hardness and drilling speed, reduce drill bit wear, and improve resistance to bending forces for a longer-lasting, faster-cutting tool.
• Conforms to ANSI Standard B212.15 - gives buyers confidence that the bit meets recognized industry benchmarks for dimensional accuracy, quality, and consistent performance.
• Straight shank design - ensures broad compatibility with standard drill chucks across a wide range of professional and trade drilling equipment.
