DWDSP4 #4 HSS Split Point Jobbers Length Drills

Manufactured to National Aerospace Standard 907, these drills are ideal for portable or machine drilling of low tensile strength alloy materials. They have a black oxide surface treatment that is abrasion resistant, reduces chip welding and improves chip flow. The 135 degree split point is self-centering and reduces thrust. Sizes smaller than 1/16" have the 118 degree standard point.
