Eagle Cutting Tool LHJ100-013-I Left-hand Hss Jobber Drill Bit

Product Description

The EAGLE CUTTING TOOL LHJ100-013-I is a 13/64-inch left-hand high-speed steel (HSS) jobber-length drill bit designed for removing broken fasteners, extracting damaged screws, and drilling in reverse-rotation applications. Left-hand fluting causes the bit to spin counterclockwise, which often backs out a stuck or broken bolt during the drilling process before an extractor is even needed. At jobber length, the bit offers a practical balance of reach and rigidity for general-purpose work in metal, wood, and plastic. It is used by electricians, plumbers, HVAC technicians, and general maintenance professionals who regularly encounter seized or stripped fasteners on the job.

This bit is suited for use in corded or cordless reversible drills set to counterclockwise rotation. Common applications include extracting broken bolts in pipe flanges, electrical enclosures, HVAC equipment panels, and mechanical assemblies. The 13/64-inch diameter makes it appropriate for working with fasteners in the No. 10 to 1/4-inch range. It is a single-piece import-grade tool suitable for light to moderate production use in trade and maintenance environments.

Key Features

• Left-hand spiral flute extracts broken fasteners during reverse drilling without a separate extractor in many cases
• 13/64-inch diameter suits common No. 10 and 1/4-inch fastener extraction work
• High-speed steel construction provides hardness and heat resistance for drilling into steel and iron
• Jobber-length geometry balances reach and rigidity for controlled drilling
• Minimum order quantity of 1 allows single-unit purchase for spot replacement

Compatibility

Designed as a standard left-hand jobber drill bit compatible with any reversible drill chuck accepting a 13/64-inch shank. Verify chuck capacity and confirm counterclockwise rotation is available on the drill being used.

Installation Notes

Left-hand drill bits are installed by trade professionals using a reversible drill or drill press set to reverse (counterclockwise) rotation. Before drilling, secure the workpiece and center-punch the broken fastener to prevent walking. Use cutting fluid when drilling into hardened steel to extend bit life and reduce heat buildup. Do not use in a drill set to forward (clockwise) rotation, as this negates the self-extracting benefit and may damage the flute geometry.
