Eagle Cutting Tool A712-020-I Hss Aircraft Drill 5/16 in

Product Description

The EAGLE CUTTING TOOL A712-020-I is a high-speed steel (HSS) aircraft extension drill bit designed for deep-reach drilling applications in metalworking, aerospace maintenance, and industrial fabrication. With a 5/16 inch diameter and a 12 inch overall length (OAL), this bit gives technicians and tradespeople the reach needed to access fastener locations that standard-length drills cannot reach. HSS construction provides solid wear resistance and heat tolerance for drilling through aluminum, mild steel, and similar materials encountered in aircraft and structural work.

This drill bit is suited for aviation maintenance, body shop work, HVAC installation, electrical rough-in, and any trade application requiring an extended-reach bit to drill through deep assemblies, structural members, or stacked materials. The 5/16 inch diameter is a common size for fastener clearance holes and pilot holes across a wide range of professional trades. It is typically used with a standard corded or cordless drill motor capable of accepting a 5/16 inch shank.

Key Features

• High-speed steel (HSS) construction for durability and heat resistance during metal drilling
• 5/16 inch diameter suits common fastener clearance and pilot hole applications
• 12 inch overall length provides extended reach into deep or obstructed work areas
• Aircraft-style geometry designed for use in aviation maintenance and deep-access drilling tasks
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as a standard extended-length HSS drill bit compatible with any drill motor or drill press accepting a 5/16 inch shank. Suitable for use in aviation maintenance, general metalworking, and trade applications requiring extended OAL drill bits.

Installation Notes

This bit is installed and used by machinists, aviation maintenance technicians, HVAC installers, electricians, and general tradespeople. Secure the shank firmly in a keyed or keyless chuck before operation and verify the bit is centered and seated before applying feed pressure. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Wear proper eye protection and follow all applicable shop safety practices when operating drilling equipment.
