Viking 04530 1/8 in HSS Heavy Duty Black Oxide Jobber Drill Bits (12 Pcs)

Viking Drill & Tool EDP# 04530 is a 12-piece pack of 1/8 in. diameter jobber-length high-speed steel (HSS) twist drills finished in black oxide, manufactured union-made in the USA to ANSI B94.11M jobber-length standards. The heavy-duty designation indicates a thick web construction for increased rigidity and resistance to drill walk and breakage compared to standard-duty equivalents; the black oxide surface treatment provides mild corrosion resistance and reduces friction at the cutting edge during drilling. These drills feature a 118° conventional split point (standard for HSS jobbers), a right-hand spiral flute, and a straight round shank compatible with 3-jaw drill chucks across bench drills, drill presses, and hand-held power drills. Intended for drilling mild steel, cast iron, aluminum, wood, plastics, and other general-purpose materials, these new drills ship in the original Viking labeled sleeve of 12.
