Hanson 30216 LH HSS Fractional Screw Machine Length - 1/4 In.

The Hanson 30216 is a professional-grade 1/4-inch left-hand high-speed steel (HSS) fractional screw machine length drill bit, designed for demanding automotive and industrial applications. This specialized bit is engineered for exceptional performance in extracting broken fasteners and other tasks requiring a robust left-hand cutting action. Its durable construction ensures reliable operation in professional workshop environments.

Key Features

• Left-Hand Cut: Specifically designed for counter-clockwise rotation, making it ideal for use with screw extractors to remove seized or broken fasteners.
• Heavy-Duty HSS Construction: Manufactured from high-speed steel for superior hardness, heat resistance, and extended tool life in rigorous use.
• Enhanced Rigidity: The screw machine length provides a shorter, more rigid design, minimizing deflection and breakage during tough drilling operations.
• Black Oxide Finish: A protective black oxide coating reduces friction, resists corrosion, and helps prevent chip welding, contributing to smoother drilling and increased tool longevity.
• 118-Degree Point: The precision-ground 118-degree point facilitates quick, accurate starts and reduces bit walking, ensuring efficient material penetration.
• Robust Web Design: Features a heavy-duty web construction that significantly enhances strength and durability, allowing it to withstand high torque applications.

Applications

This Hanson left-hand drill bit is an essential tool for professional technicians and mechanics. It is particularly effective for preparing holes for screw extractors, where its left-hand rotation helps to unthread broken bolts or screws while drilling. Its robust construction also makes it suitable for drilling into various materials, including mild steel, cast iron, and non-ferrous metals, in situations where a left-hand cutting direction is advantageous for material removal or specific assembly procedures.
