Value Collection 01000280 Aircraft Drill Bit 7/16 in

Product Description

The VALUE COLLECTION 01000280 is a 7/16-inch aircraft extension drill bit designed for deep-reach drilling applications where a standard-length bit cannot access the work area. Built from high-speed steel with an oxide finish, the bit features a 135-degree split point that reduces walking and allows self-centering on contact without a center punch. Two spiral flutes with a tapered web and web-thinned construction clear chips efficiently and reduce cutting resistance. The straight cylindrical shank is compatible with standard drill chucks. At 6 inches overall length with a 4.0625-inch flute length, this bit provides the extended reach required for structural, fabrication, and maintenance drilling tasks.

This bit is suited for general-purpose right-hand drilling in metal, plastic, and similar materials where extended reach is required. Common applications include airframe and sheet metal work, HVAC ductwork penetrations, electrical rough-in drilling through deep cavities, and maintenance tasks on equipment where standard drill bits cannot reach the target bore location. It is sized at 7/16 inch (0.4375 inch decimal) and accepts the same chuck as a standard 7/16-inch bit.

Key Features

• 135-degree split point reduces bit walking and enables self-centering on curved or flat surfaces
• Web-thinned, tapered web construction lowers thrust force and improves chip ejection
• High-speed steel construction withstands heat generated during extended drilling cycles
• Oxide finish provides mild corrosion resistance and reduces friction at the cutting edge
• 6-inch overall length with 4.0625-inch flute length delivers extended reach in confined or deep installations
• Right-hand, two-flute spiral design compatible with standard variable-speed drills and drill presses

Compatibility

Designed as a general-purpose aircraft extension drill bit with a 7/16-inch straight cylindrical shank, compatible with any standard drill chuck that accepts 7/16-inch shanks.

Installation Notes

This bit is installed and operated by machinists, sheet metal workers, electricians, and HVAC technicians using standard corded or cordless drills and drill presses. Secure the workpiece before drilling and use cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if the point is chipped or the flutes are damaged. Follow all applicable shop safety practices including eye protection and secure workholding.
