Value Collection 01220326 Left Hand Jobber Drill 1/2 in

Product Description

The VALUE COLLECTION 01220326 is a left-hand jobber-length drill bit designed for drilling operations that require reverse-direction cutting, such as removing broken fasteners and reverse-threaded applications. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this bit features a standard 118-degree point angle and a regular spiral flute. It measures 0.5 inches in diameter with an overall length of 6 inches and a flute length of 4.5 inches. The straight cylindrical shank provides secure chuck engagement in standard drill presses and hand drills. This is a general-purpose grade bit suited for everyday metal removal tasks in shop or field environments.

This left-hand drill bit is commonly used in machine shops, maintenance facilities, and manufacturing environments where reverse-rotation cutting is required. Typical applications include extracting broken bolts, drilling pilot holes in conjunction with left-hand extractors, and any operation where the workpiece or setup calls for counterclockwise cutting action. The web-thinned, tapered web configuration reduces walking and improves chip evacuation at the start of a cut. The bit ships individually and is appropriate for use in standard 1/2-inch or larger keyed and keyless chucks.

Key Features

• Left-hand cutting direction for reverse-rotation drilling and broken fastener extraction
• 118-degree standard point angle with web-thinned, tapered web for reduced entry force
• High speed steel construction for general-purpose metal drilling
• Bright, uncoated finish — no coating buildup to interfere with close-tolerance hole sizing
• Regular spiral flute, 4.5 inches long, promotes efficient chip evacuation
• Straight cylindrical shank, 0.5 inches in diameter, fits standard drill chucks

Compatibility

Designed as a general-purpose left-hand jobber drill bit for use in standard drill presses, CNC drilling machines, and hand drills equipped with a 1/2-inch or larger chuck capacity.

Installation Notes

Installation of this bit is performed by machinists and maintenance technicians. Secure the shank fully in the chuck before operation and verify the drill or drill press is set to reverse rotation before engaging the workpiece. Wear appropriate eye protection and secure the workpiece to prevent rotation. Do not exceed the recommended feed rate for the material being drilled, and allow chips to clear the flute regularly to prevent heat buildup and bit breakage.
