Drill America 13/64" x 6" High Speed Steel Aircraft Extension Drill Bit (Pack of 12), D/AA Series
Drill America D/AA/C series High-Speed Steel premium quality drill bit is manufactured to National Aerospace Standard 907. 135 degrees split point is self-centering and reduces thrust. Ideal for drilling in mild steels where extra length for reach is required. They have a black oxide surface treatment that is abrasion resistant, reduces chip welding and improves chip flow.
Product Features
- High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
- Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge
- Round shanks allow use with a wide variety of toolholding systems
- When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
- Manufactured to National Aerospace Standard 907
