Precision Twist Drill 5997013 No. 50 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5997013 is a No. 50 wire gauge high-speed steel jobber drill bit engineered for general-purpose drilling in metal and non-ferrous materials. At 0.0700 inches in decimal diameter, this bit features a 135-degree split point that reduces walking on entry and requires less feed pressure than a conventional 118-degree point. The two-flute right-hand spiral design evacuates chips efficiently from the cut. Web thinning at the tip further reduces thrust requirements, making this bit suitable for hand-held drills and drill presses alike. Licensed electricians, machinists, HVAC technicians, and plumbers reach for wire-gauge bits like this for pilot holes, tapping prep, and instrument panel work.

This bit is sized to the No. 50 wire gauge standard, equivalent to 0.0700 inches, and belongs to Precision Twist Drill Series QC21P. It is designed for right-hand drilling operations on steel, aluminum, and other non-ferrous materials. The straight cylindrical shank seats in standard drill chucks without adapters. With an overall length of 2 inches and a flute length of 1 inch, this is a compact jobber-length bit well suited to confined spaces and short-reach applications common in trade and light industrial work.

Key Features

• No. 50 wire gauge diameter — 0.0700 inches decimal equivalent
• 135-degree split point reduces bit walking and lowers entry thrust
• High-speed steel construction for durability in steel and non-ferrous stock
• Bright uncoated finish — compatible with cutting fluids and coolants
• Web-thinned tapered web for reduced feed force on small-diameter work
• Right-hand regular spiral flute for standard chuck compatibility and clean chip evacuation

Compatibility

Designed as a general-purpose jobber drill bit for use in any standard drill press, hand drill, or drill driver accepting a straight cylindrical shank. Suitable for drilling steel, aluminum, and non-ferrous workpiece materials per ANSI standards. Conforms to Series QC21P specifications.

Installation Notes

Installation is performed by machinists, maintenance technicians, electricians, or other trade professionals using standard three-jaw or keyless drill chucks. Secure the straight shank fully in the chuck before use and confirm concentricity to prevent bit breakage at this small diameter. Apply appropriate cutting fluid when drilling steel to extend tool life and maintain hole quality. Always wear eye protection and power down the drill completely before changing bits.
