Eagle Cutting Tool A712-028-I Hss Aircraft Drill 7/16 in

Product Description

The EAGLE CUTTING TOOL A712-028-I is a high-speed steel (HSS) aircraft-length drill bit designed for deep-hole drilling applications in metalworking and fabrication environments. With a 7/16-inch diameter and a 12-inch overall length (OAL), this bit provides the extended reach required when accessing recessed or deep structural members that standard-length drills cannot reach. HSS construction delivers the hardness and heat resistance needed for drilling steel, aluminum, and other common structural metals. It is a practical import-grade option for shops and field technicians who need reliable extended-reach capability without committing to premium tooling cost.

This aircraft drill bit is suited for use in metalworking, fabrication, and maintenance applications where extended reach is required. Typical use cases include drilling through aircraft frames, structural steel, tubing, and sheet metal stacks where standard jobber-length bits fall short. It is commonly used by maintenance technicians, aviation mechanics, metal fabricators, and industrial tradespeople working with drill presses, magnetic drills, or heavy-duty hand drills.

Key Features

• 7/16-inch diameter provides a substantial bore for structural fastener clearance holes
• 12-inch overall length delivers extended reach for deep or obstructed drilling locations
• High-speed steel (HSS) construction resists heat buildup during extended drilling cycles
• Import-grade value pricing suits high-consumption or disposable-tooling applications
• Minimum order quantity of 1, allowing single-unit purchase for immediate job needs

Compatibility

Designed as a standard aircraft-length drill bit compatible with any 3/8-inch or 1/2-inch chuck drill press, magnetic drill, or heavy-duty hand drill accepting round-shank bits up to 7/16-inch diameter.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist, fabricator, or maintenance technician familiar with metalworking drill speeds and feeds. Secure the bit firmly in the chuck and verify concentricity before beginning a cut to prevent bit deflection at extended length. Use cutting fluid or appropriate lubricant when drilling steel to extend bit life and maintain cut quality. Ensure the workpiece is clamped securely before drilling to prevent rotation and reduce risk of injury.
