Left Hand Cobalt SAE Mechanics Length Drill Bit - 5/32 In - Hanson

The Hanson 30510 Left Hand Cobalt SAE Mechanics Length Drill Bit is specifically engineered for professional technicians and mechanics who frequently encounter broken fasteners in demanding automotive and industrial settings. Its specialized 5/32 In left-hand cutting action is designed to prevent further tightening of damaged bolts or screws, making it an essential tool for efficient and reliable extraction.

Key Features

• Left-Hand Rotation: Engineered for counter-clockwise drilling, this design actively works to loosen and facilitate the extraction of broken fasteners when paired with spiral screw extractors.
• Cobalt High-Speed Steel (HSS) Construction: Offers exceptional heat resistance and extended durability, allowing for effective drilling through challenging materials like hardened steel, stainless steel, and cast iron.
• 135-Degree Split Point: Delivers precise, self-centering starts, significantly reducing drill bit walking and eliminating the need for a pilot hole for accurate initial placement.
• Heavy-Duty Web Design: Enhances the overall strength and robustness of the drill bit, minimizing the risk of breakage during intensive professional use in high-stress applications.

Applications

This drill bit is a critical component for any professional fastener extraction toolkit. It excels at preparing precise pilot holes in broken bolts, studs, and screws, setting the stage for successful removal with spiral screw extractors. Typical applications include the removal of snapped exhaust manifold studs on vehicles, stripped engine block bolts, and various broken fasteners found on heavy machinery. Its durable construction allows for consistent penetration of tough materials such as hardened steel, stainless steel, and high-strength alloys common in automotive repair, industrial maintenance, and heavy equipment service environments.
