Value Collection 01167709 No. 70 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01167709 is a No. 70 wire size jobber-length drill bit designed for precision drilling in aluminum and other non-ferrous materials. Ground from high speed steel (HSS) with a bright uncoated finish, it measures 0.0280 inches in diameter and delivers consistent performance in general-purpose drilling applications. The 118-degree standard point angle provides a self-centering start on flat and curved surfaces, while the web-thinned, tapered web construction reduces thrust and improves chip evacuation. The regular spiral flute with a 0.375-inch flute length keeps this compact bit cutting efficiently through thin-section and small-diameter work.

This bit is suited for light-duty production and maintenance drilling where a small-diameter, short-flute jobber bit is required. Typical applications include pilot holes, instrument panel work, electronics enclosures, and detail drilling in aluminum sheet, brass, copper, and similar non-ferrous stock. Right-hand cutting direction is standard for use in conventional drill presses, hand drills, and CNC spindles. The straight cylindrical shank accepts standard drill chucks without adapters.

Key Features

• No. 70 wire size, 0.0280-inch diameter for fine, precise drilling
• 118-degree standard point angle with web-thinned tapered web for reduced thrust
• High speed steel construction for general-purpose durability across non-ferrous materials
• Bright uncoated finish — no coating buildup to affect tight-tolerance hole size
• Regular spiral flute promotes clean chip removal in short-flute geometry
• Straight cylindrical shank fits standard drill chucks directly

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard drill chucks accepting a 0.0280-inch straight shank, including bench drill presses, portable hand drills, and CNC drilling spindles used in light metalworking and maintenance applications.

Installation Notes

Installation and use should be performed by machinists or qualified trade personnel familiar with small-diameter drill bit handling. Secure the workpiece firmly before drilling to prevent walking or bit deflection at this diameter. Power down and de-energize any machine tool before inserting or removing the bit from the chuck. Avoid excessive feed pressure on small wire-size bits, as lateral force is the primary cause of breakage at this diameter.
