Product description

Size:7/16"

The Precision Twist QC0860P extra-long length drill bit is a wide land parabolic flute design, 135-degree radius split point, round shank drill bit made of HSS with an uncoated finish. It is suitable for drilling to a depth up to ten 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 QC0860P series has a wide land parabolic flute design that enhances chip formation and evacuation of chips (also called swarf). 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. It has an uncoated finish which helps keep costs down, and provides acceptable performance in most situations. The finish helps increase chip flow in soft materials.

Drilling, or hole making, is the most common metalworking operation in the world. Twist drill bits are the most common type of drill bit used. Twist drill bits are commonly used to drill holes with hand-operated drills, standalone drill presses, or lathes. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole. These drill bits have a right-hand twist that brings chips up and away from the cutting edge. They are made to ANSI (fractional sizing) industry standards, which ensure that drill bits around the world conform to the same specifications.

Dormer Pramet manufactures cutting tools under the following brands: Precision Twist Drill, Dormer, Union Butterfield and Pramet. The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards.
