Value Collection 01220144 7/32 in Jobber Drill Bit Hss Left Hand

Product Description

The VALUE COLLECTION 01220144 is a left-hand jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree point angle suited to a wide range of common materials. The straight cylindrical shank measures 7/32 inch (0.2188 inch) in diameter, and the overall length is 3.75 inches. A regular spiral flute with a tapered web and web-thinned geometry helps clear chips efficiently during drilling. This bit is installed by machinists, maintenance technicians, and general trade professionals.

This drill bit is intended for use in left-hand rotating drill presses, lathes, or hand drills where reverse-rotation tooling is required. Left-hand bits are commonly used to extract broken fasteners and damaged screws, since the cutting direction tends to back out the fastener as the bit advances. The 7/32 inch diameter is appropriate for pilot holes, clearance holes, and fastener extraction in light to medium-duty applications across maintenance, repair, and production environments.

Key Features

• Left-hand cutting direction aids in broken fastener extraction
• 118-degree standard point angle for general-purpose use across common materials
• High speed steel construction provides good wear resistance for metal drilling
• Bright, uncoated finish maintains close dimensional tolerances
• Regular spiral flute with tapered web and web-thinned point for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without modification

Compatibility

Designed as a general-purpose left-hand jobber drill bit fitting any standard drill chuck that accepts a 7/32 inch straight cylindrical shank, including drill presses, lathes with reverse capability, and handheld reversible drills.

Installation Notes

Left-hand drill bits require a drill or machine capable of reverse (counterclockwise) rotation. Secure the workpiece firmly before drilling and use appropriate cutting fluid when drilling hardened or ferrous metals to extend tool life. Inspect the drill point for wear or chipping before each use and replace if the cutting edges are damaged. Follow applicable shop safety practices including eye protection and proper workholding.
