Value Collection 01220243 3/8 in Left Hand Hss Jobber Drill

Product Description

The VALUE COLLECTION 01220243 is a left-hand jobber-length drill bit designed for drilling applications that require reverse-rotation cutting, most commonly used when extracting broken fasteners or drilling alongside left-hand threaded components. Manufactured from high speed steel (HSS) with a bright, uncoated finish, it measures 3/8 inch in diameter with a 118-degree standard point angle. The overall length is 5 inches, with a flute length of 3.625 inches. A web-thinned, tapered web configuration reduces thrust and improves chip clearance at the cutting tip. This bit is a general-purpose grade tool suited for use in metalworking, maintenance, and repair environments.

This drill bit is intended for use in left-hand drill chucks or reversible drill presses and hand drills set to reverse rotation. It is commonly selected by machinists, maintenance technicians, and millwrights for screw extraction work, where the reverse cutting action can back out a damaged fastener while drilling. The straight cylindrical shank accepts standard drill chucks without adapters. Regular spiral flutes evacuate chips efficiently during through-hole and blind-hole operations in ferrous and non-ferrous metals.

Key Features

• Left-hand cutting direction for reverse-rotation drilling and fastener extraction
• High speed steel construction provides durability across a range of metal substrates
• 118-degree standard point angle for general-purpose drilling
• Web-thinned tapered web reduces cutting resistance and entry thrust
• Bright uncoated finish allows easy visual inspection of the cutting edge
• Straight cylindrical shank fits standard drill chucks without modification

Compatibility

Designed as a general-purpose left-hand jobber drill bit compatible with any standard keyed or keyless drill chuck accepting a 3/8-inch straight shank, including bench drill presses and reversible hand drills.

Installation Notes

Install and remove only with the drill or press unpowered and the chuck fully released. Confirm the drive tool is set to reverse rotation before use, as left-hand bits will not cut correctly in forward rotation. Use appropriate cutting fluid when drilling hardened or stainless steel to extend tool life and reduce heat buildup. Secure the workpiece firmly before drilling to prevent movement and bit deflection.
