Spline Shank Drill Bits 

Spline Shank Drill Bits

On This Page

Our carbide-tipped drill bits and accessories 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. Regular and Quad Head® bit tip configurations are available.

Fits all current and older Spline rotohammers from AEG, Black & Decker, Bosch, DeWalt, Hitachi, Kango, Makita, Metabo, Milwaukee, Ramset, Red Head and Ryobi.

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

Additional Features for Spline-Shank Bits

  • Chisel-shaped drill-bit head penetrates the material and directs concrete dust into the multi-flute spiral
  • Patented, high-volume, multi-flute spiral quickly channels concrete dust from the hole to improve drilling speed
  • 4 x 90° head geometry crushes through rebar and prevents sticking in reinforced concrete

Quad-Head Feature

  • All the features of single cutter bits and the quad-head dual-cutter are designed to improve durability and drilling speed. The high-volume, double-helix design of the quad-head bit comes with the patented, high-performance, reinforced core flute to maximize energy transfer.
