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
