Eagle Cutting Tool LHJ100-014-I Left-hand Hss Jobber Drill 7/32

Product Description

The EAGLE CUTTING TOOL LHJ100-014-I is a 7/32-inch left-hand high-speed steel (HSS) jobber-length drill bit designed for reverse-rotation drilling applications. Left-hand bits cut as the spindle turns counterclockwise, making them the standard tool for extracting broken bolts, studs, and fasteners that have snapped flush or below the surface. The HSS construction provides adequate hardness and heat resistance for drilling through mild steel, aluminum, brass, and similar materials at standard machining speeds. Machinists, auto technicians, and general maintenance trades keep left-hand bits on hand for extraction work.

This bit is suited for use in any application where a broken or seized fastener must be removed without damaging the surrounding threads or base material. Typical scenarios include removing sheared bolts from engine blocks, machine frames, and structural assemblies. The jobber-length geometry offers a practical balance between reach and rigidity, making it usable in standard drill chucks and reversible drill presses or hand drills set to reverse. It is appropriate for both shop and field use across manufacturing, automotive, and general mechanical maintenance settings.

Key Features

• Left-hand spiral flute cuts on counterclockwise rotation for broken fastener extraction
• 7/32-inch diameter matches common small-bolt and stud sizing
• High-speed steel construction handles mild steel, aluminum, and non-ferrous metals
• Jobber-length design fits standard 3-jaw drill chucks without adapters
• Minimum order quantity of 1 allows single-unit purchase for spot needs

Compatibility

Designed as an OEM-style replacement or stock bit compatible with any standard drill chuck accepting 7/32-inch shank diameters, including reversible hand drills, drill presses, and CNC equipment running counterclockwise programs.

Installation Notes

Left-hand drill bits require the drill or drill press to be set to reverse (counterclockwise) rotation before use. Secure the workpiece firmly before drilling to prevent movement that can snap the bit. Use cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Wear appropriate eye protection and follow applicable shop safety standards during all drilling operations.
