The Precision Twist QC21P jobber drill bit is a parabolic flute design, 135-degree radius, split-point, round shank drill bit made of HSS with an uncoated (bright) finish. It is suitable for drilling to a depth up to four times the diameter of the drill. Good for portable or machine drilling. The shank diameter is the same as the drill size. It was designed for drilling holes into a wide variety of metals and synthetic materials with best performance in steel and cast iron. The QC21P series has a wide land parabolic flute design that enhances chip (also called swarf) formation and evacuation. Coolant has a better flow to the drill point for heat dissipation, and higher speeds and feeds for increased productivity. It is recommended to use a constant heavy feed rate while drilling. This design has a reinforced web which provides increased drill strength and rigidity, and straighter closer tolerance holes. The uncoated finish helps keep costs down, yet provides acceptable performance in most situations. The finish helps increase chip flow in soft materials. and away from the cutting edge. They are made to ANSI industry standards, which help ensure that drill bits around the world conform to the same specifications.
