Eagle Cutting Tool A712-127-I Hss Aircraft Drill 12in

Product Description

The EAGLE CUTTING TOOL A712-127-I is a Number 27 high-speed steel (HSS) aircraft-length drill bit with a 12-inch overall length (OAL). Designed for deep-reach drilling applications, the extended OAL allows access to recessed or stacked-material locations that standard-length bits cannot reach. HSS construction provides the hardness and heat resistance needed for continuous use in metal, composite, and structural materials common in aviation, automotive, and general fabrication work. This bit is handled by machinists, aircraft maintenance technicians, and fabricators working where reach and precision matter.

Aircraft-length drill bits like the A712-127-I are used in applications requiring extended reach through airframes, structural panels, sheet metal assemblies, and deep-set fixtures. The Number 27 diameter is a common size for clearance and tapping operations in light metalwork. This bit is suited for both bench drill press use and handheld drill motors in shop or field environments.

Key Features

• Number 27 drill size for precise diameter control in clearance and tapping applications
• 12-inch overall length provides extended reach for deep or obstructed drilling locations
• High-speed steel (HSS) construction resists heat buildup during continuous drilling
• Aircraft-length geometry designed for structural and sheet metal work
• Minimum order quantity of 1 for single-unit purchasing

Compatibility

Designed as a standard aircraft-length HSS drill bit compatible with any 3-jaw chuck or drill motor accepting a standard straight shank in the Number 27 size range.

Installation Notes

This bit is installed and operated by machinists, aircraft maintenance technicians, and metal fabricators. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid for metal drilling to extend bit life and reduce heat. Inspect the cutting edges for wear or chipping before each use and replace if the tip is damaged.
