Value Collection BS27N0079 No. 79 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION BS27N0079 is a wire gauge jobber-length drill bit sized to No. 79 (0.0145 inch diameter), designed for precision drilling in aluminum, non-ferrous metals, and soft materials. Built from high speed steel (HSS) with a bright, uncoated finish, this bit features a 130-degree point angle and a slow spiral flute configuration for clean chip evacuation in softer workpiece materials. The web-thinned, tapered web design reduces thrust and helps maintain accurate entry. With an overall length of 0.75 inch and a flute length of 0.1875 inch, this is a compact, small-diameter bit suited for close-tolerance work in machining and fabrication environments.

This drill bit is intended for use in light machining, electronics assembly, instrument fabrication, and general shop work where small-diameter, wire gauge holes are required. The No. 79 size makes it appropriate for tapping pilot holes, wire routing clearances, and precision layout work on aluminum and non-ferrous stock. The straight cylindrical shank fits standard drill chucks and collets commonly used in bench drill presses, CNC machines, and hand drills. Right-hand cutting direction is compatible with conventional drilling setups.

Key Features

• No. 79 wire gauge size — 0.0145 inch diameter for precision small-bore applications
• 130-degree split point angle reduces walking and improves entry accuracy
• Slow spiral flute geometry optimized for aluminum and non-ferrous materials
• High speed steel construction provides durability across general-purpose drilling tasks
• Web-thinned tapered web lowers drilling thrust on small-diameter work
• Bright uncoated finish — no coating buildup to alter critical diameter tolerances

Compatibility

Designed as an OEM-style replacement or stock drill bit for standard wire gauge drill sets requiring a No. 79 size with a straight cylindrical shank and slow spiral flute geometry.

Installation Notes

Installation of this bit is performed by machinists and general trade professionals using standard drill chucks or collets. Ensure the drill press or hand tool is powered down and secured before changing bits. Use appropriate spindle speeds for small-diameter HSS bits in non-ferrous materials — excessively high feed rates can snap bits at this diameter. Coolant-through is not supported; use cutting fluid applied externally when drilling harder non-ferrous alloys.
