Eagle Cutting Tool LHJ100-021-I Left-hand Hss Jobber Drill

Product Description

The EAGLE CUTTING TOOL LHJ100-021-I is a 21/64-inch left-hand high-speed steel (HSS) jobber-length drill bit designed for reverse-rotation drilling applications. Left-hand drill bits spin counterclockwise, making them the standard choice for extracting broken fasteners and studs — the cutting action often backs out the damaged fastener before a full hole is drilled. HSS construction provides durability across a range of materials including mild steel, aluminum, wood, and plastics. This bit is an import-grade option suited for shop technicians, maintenance crews, and trade professionals who need reliable left-hand drilling at a practical price point.

This bit is used wherever a left-hand drill is required: extracting broken bolts, removing seized studs, and drilling pilot holes with reverse-rotation tooling. It fits standard drill chucks and is compatible with reversible corded and cordless drills as well as drill presses set to reverse rotation. Common applications include automotive repair, HVAC equipment service, plumbing fixture work, and general metal fabrication where broken fastener removal is a routine task.

Key Features

• Left-hand (counterclockwise) cutting geometry for reverse-rotation drilling and fastener extraction
• 21/64-inch diameter HSS construction for use in mild steel, aluminum, and similar materials
• Jobber-length flute provides a balance of reach and rigidity for general-purpose drilling
• Fits standard drill chucks on reversible drills and drill presses
• Minimum order quantity of 1 — available as a single bit

Compatibility

Designed as a general-purpose left-hand jobber drill bit compatible with any reversible drill or drill press accepting a standard round-shank bit in a 21/64-inch diameter.

Installation Notes

Left-hand drill bits must be used with a drill set to reverse (counterclockwise) rotation. Secure the workpiece firmly before drilling to prevent movement and ensure the drill is fully seated in the chuck. Use appropriate cutting fluid when drilling metal to extend bit life and improve cut quality. Eye protection is required during all drilling operations.
