Value Collection 01220169 Left Hand Jobber Drill Bit E

Product Description

The VALUE COLLECTION 01220169 is a left-hand jobber-length drill bit sized to Letter E, equivalent to 0.250 inches in diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree split point and a regular spiral flute for efficient chip evacuation. The straight cylindrical shank measures 0.250 inches in diameter, and the overall length is 4 inches with a flute length of 2.75 inches. Left-hand cutting direction makes this bit particularly useful for removing broken fasteners and reverse-threaded applications. It is intended for use by machinists, maintenance technicians, and metalworking professionals.

This drill bit is suited for general-purpose drilling in steel and cast iron in both shop and field environments. The web-thinned, tapered web configuration reduces thrust required at the cutting tip, improving performance in ferrous metals. Typical applications include bolt extraction, production drilling, and maintenance repair operations where a left-hand spiral is required to back out damaged or seized fasteners without additional tooling. It is sold individually and is compatible with standard drill chucks and drill presses accepting a 0.250-inch straight shank.

Key Features

• Left-hand cutting direction for reverse-rotation drilling and broken bolt extraction
• High-speed steel construction for durability in ferrous metal applications
• 118-degree standard point angle for general-purpose use in steel and cast iron
• Web-thinned tapered web reduces cutting thrust and improves bit entry
• Bright, uncoated finish — no coating to obscure wear and suitable for regrinding
• Straight cylindrical shank fits standard drill chucks accepting 0.250-inch shanks

Compatibility

Designed for general-purpose use in standard drill chucks and drill presses that accept a 0.250-inch straight cylindrical shank. Primary workpiece materials are steel and cast iron.

Installation Notes

This bit is installed by a machinist or maintenance technician into any drill chuck rated for a 0.250-inch straight shank. Ensure the workpiece is securely clamped before drilling. When using for broken fastener removal, the drill press or driver must be set to reverse rotation to engage the left-hand flute correctly. Inspect the cutting edges before each use and replace or regrind when wear is visible to maintain safe cutting performance.
