DEWALT concrete drill bit for rotary hammer with spline shank Review

This concrete drill bit is designed to stand up to even the hardest aggregate, making it ideal for professional use. The high impact tip of the bit ensures maximum carbide surface contact, which in turn, increases its longevity. Additionally, the open head design of the bit channels the dust into flutes for quicker and more efficient drilling. The longer helix four flute design also expedites mill removal, making it one of the fastest drilling bits in the market. The concave head and double flute design further enhance this drilling speed by enabling quick removal of dust from the hole, thereby reducing breakage.This drill bit is perfect for heavy-duty work, and its 4-cutter heads reduce vibrations, thus minimizing user fatigue. The elongated helix also expedites mill removal, further reducing the time and effort required for drilling.
