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 SDS-MAX, Spline and Select SDS-PLUS 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. Proprietary flute geometry reduces vibration and optimizes impact energy. Transfers from the rotary hammer into the drill bit tip which enhances drilling speed and durability and reduces noise, stress and vibration on the operator.
