The Tru-Cut HDC.437 is a professional-grade 7/16 inch (0.437") jobber length drill bit designed for heavy-duty applications. Manufactured from high-speed steel (HSS), this drill bit features a black and gold oxide finish that provides corrosion resistance and enhanced wear protection for extended tool life.

Key Features:

• 7/16 inch diameter for versatile drilling applications
• 135-degree split point design prevents walking and eliminates the need for center punching
• Black and gold oxide coating offers superior rust resistance and increased hardness
• Jobber length provides optimal balance between reach and rigidity
• High-speed steel construction for durability and heat resistance
• Spiral flute design efficiently evacuates chips and allows coolant to reach cutting edges
• Round shank fits standard drill chucks

Ideal for drilling through metal, steel, wood, plastic, and fiberglass. The self-centering split point penetrates material quickly without a pilot hole and produces smaller chips to reduce clogging. Tru-Cut drill bits meet ANSI specifications B-94-1977 and federal GGG-D-75ic standards, ensuring consistent quality and performance for professional and industrial applications.
