Description

This item is brand-new, factory sealed.

Drill America 3/8" x 12" High Speed Steel Aircraft Extension Drill Bit (Pack of 6), DWDA/C Series
  • 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

Drill America DWDA/C Series High-Speed Steel drill bit is manufactured to National Aerospace Standard 907. 135 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.
