The Precision Twist QC21GM jobber drill bit is a parabolic flute design, 135-degree radius, split-point, round shank drill bit made of HSS with a TiN 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, cast iron, copper, and aluminum magnesium . The QC21GM 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 with this design 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. Titanium nitride (TiN) is a gold-colored ceramic coating that combines hardness and low friction to extend cutting tool life and permits faster cutting speeds than with uncoated tools. Good for use on items made of alloy steel, carbon steel, plastic, and aluminum. The finish helps increase chip flow in soft materials. and away from the cutting edge. They are made to DIN 338 (metric sizing) industry standards, which ensure that drill bits around the world conform to the same specifications.
