About this item

  • 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
  • For general purpose drilling in applications where extra length for reach is required, designed to perform in a broad range of materials in the iron and steel families
  • 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.

I like that it came in a set. I used it to drill holes through aluminum and wood at the same time that was about 2” thick. I was surprised how sharp and easy it drilled.
