9/16" Reduced Shank Black Oxide Drill Bit (3/8" Shank) - DeWALT

The DeWALT DW1620 9/16" Reduced Shank Black Oxide Drill Bit is engineered for professional technicians and mechanics requiring precise and efficient drilling in demanding applications. Featuring a robust black oxide coating and a specialized flute design, this drill bit delivers enhanced durability and optimal chip ejection for consistent performance across various materials. Its reduced shank allows for compatibility with a wider range of drill chucks, making it a versatile addition to any professional toolkit.

Key Features

• 135-degree Split Point: Enables immediate drilling on contact, preventing bit walking and ensuring accurate hole placement from the start.
• Parabolic Flute Design: Optimized to improve chip ejection efficiency in both metal and wood drilling applications, reducing heat buildup and preventing clogging.
• Black Oxide Coating: Provides increased wear resistance, extending the life of the drill bit in high-demand industrial and automotive environments.
• 31-degree Helix Angle: Specifically designed to minimize the over-aggressiveness often associated with true parabolic flutes, offering a controlled and smooth drilling experience.
• Reduced 3/8" Shank: Allows the 9/16" cutting diameter to be used in standard 3/8" drill chucks, enhancing tool compatibility and versatility.

Applications

This DeWALT drill bit is well-suited for a variety of professional tasks, including metal fabrication, automotive repair, and industrial maintenance. It excels in drilling through steel, aluminum, and other common workshop materials, making it ideal for creating holes for fasteners, conduit, or other structural components. Its robust construction supports consistent use in general construction and MRO (Maintenance, Repair, and Operations) settings.
