15/64" Left-Hand Drill Bit - Hanson

The Hanson 62315 15/64" Left-Hand Drill Bit is a specialized tool engineered for professional technicians and mechanics to efficiently remove broken fasteners. Designed for counter-clockwise rotation, this robust drill bit prevents seized hardware from being driven deeper into the workpiece while simultaneously preparing it for extraction.

Key Features

• Left-Hand Helix Design: Specifically engineered for counter-clockwise rotation, this design helps to back out broken bolts, studs, and screws during the drilling process, making it an ideal bit 15 for extraction.
• Precision-Ground Cutting Edges: Ensures accurate, concentric pilot holes and efficient chip removal, critical for effective fastener extractor engagement.
• Professional-Grade Durability: Constructed with Hanson's established quality, 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, also referred to as 15 64, is compatible with various bolt extractor sets and suitable for a range of small to medium fastener removal tasks.
• Reversible Drill Compatibility: Designed for optimal performance with variable-speed reversible drills or drill presses, enabling the controlled left-hand rotation required for successful extraction.

Applications

This 15/64" left-hand drill bit is essential 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. Proper use of the left-hand action can often loosen and extract a broken fastener during drilling, potentially reducing the need for more aggressive extraction methods.
