HSS Screw Machine Drill Bit 21/64 In - Hanson

The Hanson 30121 21/64" HSS Screw Machine Drill Bit is a robust and reliable tool designed for professional automotive and industrial applications. This high-speed steel "stubby" drill bit is engineered for enhanced strength and rigidity, providing precise and efficient drilling in demanding environments.

Key Features

• High-Speed Steel (HSS) Construction: Manufactured from M-2 high-speed steel, this drill bit offers an excellent combination of strength, heat resistance, and wear resistance for extended tool life in rigorous use.
• Screw Machine Length: The shorter overall length of this "stubby" drill bit significantly increases its strength and rigidity, reducing deflection and minimizing breakage, especially when drilling tough materials or in confined spaces.
• 135-Degree Split Point: Features a self-centering 135-degree split point that ensures a true start and eliminates drill bit "walking" on the workpiece, allowing for quick and accurate penetration without the need for a pilot hole.
• Black Oxide Finish: A black oxide coating provides added corrosion resistance and enhanced lubricity, improving chip flow and contributing to better performance and longevity.

Applications

This Hanson HSS screw machine drill bit is ideally suited for professional technicians and mechanics working in industrial and automotive repair settings. It excels in drilling through various materials including steel, cast iron, and other alloys, where durability and precision are paramount. The robust design and shorter length make it particularly effective for high-torque applications, such as drilling out broken bolts, creating accurate holes for fasteners in heavy machinery, or performing tasks in tight access areas within vehicle engines or industrial equipment. Its ability to maintain rigidity and resist heat makes it a valuable asset for demanding professional drilling operations.
