15/64" Left-Hand Drill Bit - Hanson

The Hanson 62315 15/64" Left-Hand Drill Bit is a purpose-built tool designed for professional technicians and mechanics to effectively remove broken fasteners. Engineered for counter-clockwise rotation, this robust drill bit works to prevent seized hardware from being driven deeper into the material while simultaneously preparing it for extraction. This design often helps to back out broken bolts, studs, and screws during the drilling process itself.

Key Features

• Left-Hand Helix Design: Specifically engineered for counter-clockwise rotation, this design actively aids in loosening and backing out broken fasteners during drilling, reducing the need for additional extraction steps.
• Precision-Ground Cutting Edges: Ensures accurate, concentric pilot holes and efficient chip removal, which is crucial for successful engagement with fastener extractor sets.
• Professional-Grade Durability: Constructed with Hanson's established quality standards, this drill bit is built to withstand rigorous daily use in demanding automotive, diesel, and industrial environments.
• Optimal 15/64" Diameter: This versatile pilot size is compatible with a wide range of bolt extractor sets and is suitable for various small to medium fastener removal tasks.
• Reversible Drill Compatibility: Designed for optimal performance with variable-speed reversible drills or drill presses, enabling the precise left-hand rotation required for controlled extraction.

Applications

This 15/64" left-hand drill bit is an essential tool for automotive and light truck repair, particularly for removing broken exhaust manifold bolts, bracket fasteners, and engine accessory hardware from cylinder heads, blocks, and aluminum components. Its utility extends to fleet maintenance, heavy-duty industrial equipment service, and shop fabrication, where precise drilling and extraction of snapped fasteners are crucial without damaging surrounding materials.
