Eagle Cutting Tool A700-028-I Hss Aircraft Drill 7/16 in

Product Description

The EAGLE CUTTING TOOL A700-028-I is a high-speed steel (HSS) aircraft extension drill bit designed for reaching into deep or obstructed bore locations that standard-length drills cannot access. With a 7/16 inch cutting diameter and a 6 inch overall length (OAL), this bit provides the extended reach required for aircraft-style drilling applications in metal fabrication, mechanical assembly, and structural work. HSS construction delivers the hardness and heat resistance needed for drilling ferrous and non-ferrous metals. This type of bit is commonly used by machinists, maintenance technicians, and metalworking professionals who need reliable penetration at extended depths.

Aircraft extension drills are a standard tool in metal fabrication shops, HVAC installation, mechanical contracting, and industrial maintenance. The 7/16 inch diameter suits common fastener clearance holes and structural pilot holes. The 6 inch OAL allows technicians to drill through assemblies, panels, or framing where a jobber-length bit would bottom out before completing the hole. This is an import-grade bit suited for general-purpose production and service work where frequent replacement is expected.

Key Features

• 7/16 inch cutting diameter for standard fastener and clearance hole applications
• 6 inch overall length provides extended reach into deep or confined work areas
• High-speed steel (HSS) construction resists heat buildup during metal drilling
• Aircraft-style extension geometry for straight, true holes at depth
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as a general-purpose HSS aircraft extension drill bit compatible with standard three-jaw drill chucks and keyed chucks accepting a 7/16 inch shank diameter on corded drills, drill presses, and magnetic base drills.

Installation Notes

Secure the bit fully in the chuck before operation and verify concentricity to minimize runout at the extended length. Use appropriate cutting fluid or lubricant when drilling steel to extend bit life and reduce heat. Operators should wear eye protection and secure the workpiece firmly. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
