Value Collection 01220086 Left Hand Jobber Drill 1/8 in Hss

Product Description

The VALUE COLLECTION 01220086 is a left-hand jobber-length drill bit designed for standard drilling operations where a reverse-cutting direction is required. Ground from high speed steel (HSS) with a bright, uncoated finish, this bit features a 118-degree standard point angle suited for general-purpose work in a wide range of materials including mild steel, aluminum, wood, and plastics. The straight cylindrical shank measures 1/8 inch in diameter, matching the bit diameter for direct chuck mounting. Overall length is 2.75 inches, with a flute length of 1.625 inches. The web is thinned and tapered for improved chip clearance and reduced thrust at the point.

Left-hand drill bits are primarily used by machinists and maintenance technicians to remove broken bolts, studs, and fasteners. As the drill contacts a stuck fastener and begins to cut, the reverse rotation often causes the fastener to back out before a full extraction procedure is needed. This bit is appropriate for use in reverse-capable drill presses, hand drills, and screw extractors. It is a general-purpose grade suitable for light to moderate production drilling and maintenance repair work across metal fabrication, mechanical service, and industrial maintenance applications.

Key Features

• Left-hand cutting direction aids in broken fastener and stud removal
• 118-degree standard point angle for general-purpose drilling in common materials
• High speed steel construction provides adequate hardness and wear resistance for production and maintenance use
• Bright uncoated finish allows easy visual inspection of the cutting edges
• Web-thinned, tapered web reduces cutting resistance and improves chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose left-hand jobber drill bit compatible with any standard drill press, hand drill, or reversible power tool equipped with a chuck sized to accept a 1/8-inch straight shank.

Installation Notes

Install and remove this bit only when the drill or press is powered down and the chuck is fully stationary. Secure the straight shank firmly in a properly sized chuck to prevent slippage during left-hand rotation. When using this bit for broken fastener removal, ensure the workpiece is clamped securely before applying pressure. Wear appropriate eye protection per standard shop safety practices.
