Champion 704-7/16 7/16" Taper Length Drill – Straight Shank, 118° HSS
704-7/16 is a Champion 704 medium-duty surface-treated high-speed steel taper length drill in 7/16" (0.4375 inch decimal equivalent). Its extended taper-length design provides more reach than a standard jobber drill while keeping the shank at the same nominal diameter as the drill.
Key Benefits
- Taper-length design provides approximately the same overall flute length as taper shank drills and more reach than standard jobber drills.
- Straight shank has the same nominal diameter as the drill for compatible chucks and machine tooling.
- 118° point supports controlled starts and dependable holemaking.
- Surface-treated HSS enhances heat resistance for longer, smoother drilling.
Applications
- Lathe and screw machine applications
- Low-carbon steels and alloyed steels
- Steel drop forgings and grey cast iron
- Extended-reach drilling where a standard jobber drill is too short
