Feature

●High speed steel tools are suitable for most general applications and provide a combination of hardness and toughness for wear resistance.
●Black oxide treatment adds lubrication, and creates small pockets on the surface of the tool that keep coolants close to the cutting edge.
●Round shanks allow use with a variety of tool holding systems.
●If they run counterclockwise (right-hand cutting) spiral corrugated tools evacuate chips from the cut and thus reduce clogging.
●Manufactured to the national aerospace standard 907.


Description

America DWDA/C Series High-Speed Steel Drill Bit is manufactured according to National Aerospace Standard 907. 135 split point is self-centered and reduces thrust Ideal for drilling in mild steel where extra length is required for greater reach They have a black oxide surface treatment that is abrasion resistant, reduces splintering welding and improves chip flow.
