Hertel C.E03.0278 Aircraft Drill Bit 7/64 in Hss

Product Description

The HERTEL C.E03.0278 is an aircraft extension drill bit designed for drilling in tight or hard-to-reach spaces where a standard-length bit cannot reach. Built from high-speed steel with an oxide finish, this bit measures 7/64 inch (0.1094 inch decimal) in diameter and runs 6 inches in overall length. The 135-degree split point is self-centering, reducing the need for a center punch and minimizing walking on hard surfaces. Two spiral flutes with a 1.5-inch flute length clear chips efficiently. The web-thinned, tapered web construction reduces feed pressure during drilling. This bit is suited for use by HVAC technicians, electricians, plumbers, and sheet metal workers who need extended reach in confined installations.

This aircraft extension drill bit is a general-purpose tool appropriate for metal, light structural steel, and similar materials encountered in trade work. The extended 6-inch overall length makes it well suited for drilling through wall plates, ductwork flanges, equipment cabinets, and structural members where standard bits fall short. The straight cylindrical shank fits standard drill chucks without adapters. Right-hand cutting direction is compatible with all standard corded and cordless drills.

Installation Notes

This bit is installed and used by trade professionals including HVAC technicians, electricians, and plumbers. Secure the workpiece before drilling and confirm the drill chuck is properly tightened before operation. Use appropriate cutting speed for the material being drilled to avoid overheating the bit. Wear appropriate eye protection whenever drilling operations are performed.
