Description
The Precision Twist QC91G taper-length drill bit is a parabolic flute design, 135-degree radius, split-point, round shank drill bit made of HSS with a TiN finish, which is a hard, gold-colored ceramic coating that has low friction, permitting faster cutting speeds than uncoated materials. It is suitable for drilling to a depth up to six 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 QC91G 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 can operate at 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.
and away from the cutting edge. They are made to ANSI (fractional) industry standards, which helps ensure that drill bits around the world conform to the same specifications.
