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
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.
