Feature(may vary by option.)

●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 tool holding 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

Description

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.
