Eagle Cutting Tool A712-131-I Hss Aircraft Drill Size 31

Product Description

The EAGLE CUTTING TOOL A712-131-I is a Size 31 high-speed steel (HSS) aircraft-length drill bit with a 12-inch overall length (OAL). Designed for deep-hole drilling applications common in aerospace, aviation maintenance, and structural fabrication work, the extended OAL allows access to workpieces and assemblies where standard-length bits cannot reach. HSS construction provides sufficient hardness and heat resistance for drilling through aluminum, mild steel, and other materials typically encountered in aircraft and sheet-metal work. Machinists, airframe mechanics, and metal fabricators are the primary users of this style of bit.

This drill bit is suited for use in hand-held electric drills, drill presses, and pneumatic drilling tools in both shop and field environments. The aircraft-length design is particularly useful when drilling through structural members, fuselage panels, and stacked material where bit reach is the limiting factor. Import construction keeps the cost per bit practical for high-consumption shop environments.

Key Features

• Size 31 wire gauge diameter for precision hole sizing in metal fabrication and aircraft work
• 12-inch overall length provides extended reach for deep or obstructed drilling applications
• High-speed steel (HSS) construction offers hardness and wear resistance across common metals
• Aircraft-length format compatible with standard drill chucks and pneumatic drilling equipment
• Minimum order quantity of 1, allowing single-unit purchase

Compatibility

Designed as an aircraft-length replacement drill bit suitable for use with standard three-jaw drill chucks accepting wire-gauge-size bits in electric, pneumatic, and drill-press applications.

Installation Notes

Installation of this drill bit is performed by machinists, airframe mechanics, and metal fabricators. Secure the bit firmly in the chuck and verify it is fully seated and centered before drilling. Always wear appropriate eye protection and secure the workpiece before operation. Follow applicable shop safety standards and, where relevant, manufacturer guidelines for drilling speed and feed rate based on material type.
