Key Features

  • NAS 907 type B standards, used in the aerospace industry
  • Extra-length drill bits, provide long reach
  • 135-degree split-point angles, is self-centering, reduces walking, good for hard material, and reduces pressure on cutting edges
  • Steam tempering (also called black oxide) retains cutting fluid and prevents chip to tool welding
  • High-speed steel (HSS), for use on a wide variety of materials

Product Description

The Precision Twist 500-6 extra-length, aircraft extension drill bit, is a round shank bit made of HSS with a steam tempering (also called black oxide) finish. It is suitable for drilling to a depth up to four times the diameter of the drill. The shank diameter is the same as the drill size. Best performance with drilling into hardened, tempered alloy steel, stainless steel, and titanium. These should be less than 30 on the Rockwell C hardness scale.

While the 500-6 series was designed for aircraft industry, they also work well for drilling into a variety of materials. The extra length and 135-degree split point drill geometry provide extra reach and ensure an accurate hole by reducing walking when the hole is started. The finish retains lubricants to aid in wear resistance and chip flow.

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) and NAS 907 type B industry standards, which helps ensure that drill bits around the world conform to the same specifications.

Precision manufactures machine tools under the following brands: Precision Twist, Precision Dormer, and Union Butterfield. They have locations around the world, and provide tools adhering to ANSI, NAS, and DIN standards.
