Key Features

  • NAS 965 type B standards, used in the aircraft industry
  • Threaded hex shank, quickly threads into drills and drill attachments
  • 135-degree split-point angles is self-centering, reduces walking, good for hard material and reduces pressure on cutting edges
  • Steam tempering (back oxide) finish retains cutting fluid and prevent chip to tool welding
  • High-speed steel (HSS), for use on a wide variety of materials

Product Description

The Precision Twist TS18 short series, aircraft-threaded, hex shank split-point drill bit is made of HSS with a steam tempering (also called black oxide) finish. Designed for medium-duty service, they are good for drilling into low tensile strength materials in confined spaces.

While the TS18 series was designed for aircraft industry, they also work well in other industries. The short length and 135-degree split point drill geometry provide good maneuverability in confined spaces 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. HSS assures good performance at an economical cost.

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 NAS 907 type B industry standards, which 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.
