Eagle Cutting Tool A712-140-I Hss Aircraft Drill 12 in Oal

Product Description

The EAGLE CUTTING TOOL A712-140-I is a Number 40 high-speed steel (HSS) aircraft-extension drill bit with a 12-inch overall length (OAL). Designed for drilling in tight or deep-clearance applications, the extended shank gives technicians reach that standard-length bits cannot provide. HSS construction handles a wide range of materials including mild steel, aluminum, and plastics. At 0.31 pounds, the bit is lightweight enough for overhead and confined-space work without adding fatigue. This drill is suited for professional trades requiring precise, small-diameter holes in sheet metal, structural panels, and fabrication work.

The A712-140-I is used in applications where standard drill bit length is insufficient, such as airframe work, HVAC sheet metal fabrication, electrical panel drilling, and general mechanical assembly. The Number 40 wire gauge diameter makes it a go-to size for pilot holes, rivet preparation, and small fastener clearance holes. It is appropriate for use in both hand-held drills and drill press setups on production or job-site work.

Key Features

• Number 40 wire gauge diameter for small-clearance and pilot-hole work
• 12-inch overall length provides extended reach in deep or confined spaces
• High-speed steel (HSS) construction for durability across metal, aluminum, and plastic substrates
• Lightweight at 0.31 pounds for reduced fatigue during extended use
• Suitable for hand-held drill and drill press applications

Compatibility

Designed as an OEM-style extended-length replacement drill bit compatible with standard drill chucks accepting wire-gauge Number 40 HSS aircraft-extension bits.

Installation Notes

This bit is installed by qualified tradespeople including HVAC sheet metal technicians, electricians, and mechanical fabricators. Secure the bit fully in the chuck before operation and verify chuck key is removed prior to powering the drill. Use appropriate cutting fluid when drilling ferrous metals to extend bit life. Follow applicable shop safety standards and wear eye protection at all times when drilling.
