Left Hand Fractional Drill Bit - 3/16In - Hanson

The Hanson 30212 3/16" Left Hand Fractional Drill Bit is engineered for demanding professional automotive and industrial applications, particularly effective for stubborn fastener removal. This heavy-duty, high-speed steel (HSS) drill bit is designed to rotate counter-clockwise, making it an indispensable tool for extracting broken screws and bolts without inadvertently tightening them further.

Key Features:

• Left-Hand Rotation: Specifically engineered to operate in a counter-clockwise direction, ideal for use with screw extractors to effectively loosen and remove broken fasteners.
• Heavy-Duty HSS Construction: Manufactured from robust high-speed steel, providing exceptional wear resistance and extended tool life under rigorous professional use.
• Screw Machine Length: The shorter, compact design enhances rigidity and minimizes deflection, ensuring greater control and reducing the risk of breakage in confined or high-stress applications.
• 118-Degree Point: Features an optimized 118-degree point for precise self-centering, enabling quick and accurate starts while facilitating efficient material removal.
• Black Oxide Finish: A black oxide coating enhances lubricity and provides improved corrosion resistance, contributing to the drill bit's durability and consistent performance.
• Reinforced Web Design: Incorporates a heavy-duty web construction for superior strength and resilience, capable of withstanding the demands of challenging drilling and extraction tasks.

Applications:

This professional-grade 3/16" left-hand drill bit is primarily used for the precise and effective removal of seized, stripped, or broken fasteners. It is an essential tool for automotive technicians, industrial mechanics, and maintenance professionals performing tasks such as engine repair, machinery overhaul, or general fabrication where the extraction of stubborn components is required. Its specialized design ensures efficient operation when conventional right-hand drilling methods are impractical or counterproductive.
