Value Collection 01220193 Jobber Drill 19/64 in Hss Left Hand

Product Description

The VALUE COLLECTION 01220193 is a left-hand jobber-length drill bit designed for use in metal fabrication, maintenance, and general-purpose drilling applications. Ground from high speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree split point and a web-thinned, tapered web configuration that reduces thrust and improves chip ejection. The straight cylindrical shank measures 19/64 inches in diameter (0.2969 inches decimal), and the overall length is 4-3/8 inches with a regular spiral flute running 3-1/16 inches. It is sized for use in standard drill chucks and reversible drill presses or hand drills.

This bit is intended for left-hand drilling operations, which are commonly used by maintenance technicians and machinists to extract broken fasteners and stripped screws. The left-hand cutting direction allows the bit to back out damaged fasteners as it penetrates, reducing the need for separate extraction tools. Primary workpiece materials include steel and cast iron, making this an appropriate choice for general shop and field service work. No coolant-through capability is present, so surface lubrication or cutting fluid applied externally is recommended when drilling harder alloys.

Key Features

• Left-hand cutting direction for broken fastener extraction and reverse-drilling operations
• 118-degree standard point angle with web thinning for reduced entry thrust
• High speed steel construction suited for steel and cast iron workpieces
• Bright, uncoated finish for general-purpose use
• Straight cylindrical shank fits standard drill chucks without adapters
• Regular spiral flute promotes efficient chip clearance

Compatibility

Designed as a general-purpose jobber drill bit for use in standard 3/8-inch or 1/2-inch keyed or keyless drill chucks, reversible drill presses, and hand drills that accept a 19/64-inch straight shank.

Installation Notes

This bit is installed by qualified machinists, maintenance technicians, or trade professionals familiar with drilling equipment. Secure the shank fully in the drill chuck before operation and verify the drill is set to reverse rotation before use. Apply a suitable cutting fluid or lubricant to the work surface when drilling steel or cast iron to extend bit life and improve hole quality. Inspect the cutting edges for wear before each use and replace the bit if chipping or dullness is observed.
