Eagle Cutting Tool A700-128-I Hss Aircraft Drill No. 28

Product Description

The EAGLE CUTTING TOOL A700-128-I is a No. 28 high-speed steel (HSS) aircraft-extension drill with an overall length of 6 inches. Designed for deep-reach drilling applications where a standard-length bit cannot access the work area, this drill is a staple in aviation maintenance, HVAC sheet metal work, and general fabrication. HSS construction provides the hardness and heat resistance needed for drilling steel, aluminum, and other common trade materials. At 0.37 pounds, it is light enough for extended use with a pistol-grip drill or right-angle driver.

This aircraft drill is suited for residential and commercial applications where extended reach is required — including drilling through deep structural members, ductwork flanges, electrical enclosures, and tight mechanical assemblies. The No. 28 wire gauge diameter makes it well matched for tapping, riveting, and fastener pilot holes in light metal fabrication. HVAC technicians, electricians, sheet metal workers, and maintenance mechanics commonly keep this size in rotation for field work.

Key Features

• No. 28 wire gauge diameter for precise pilot and tap holes in metal
• High-speed steel (HSS) construction for hardness and heat resistance during metal drilling
• 6-inch overall length provides extended reach into confined spaces and deep assemblies
• Lightweight at 0.37 pounds for reduced fatigue during extended use
• Compatible with standard drill chucks used in pistol-grip and right-angle drills

Compatibility

Designed as an OEM-style replacement or direct-use aircraft-extension drill for applications requiring a No. 28 HSS bit with a 6-inch overall length, suitable for use with standard drill chucks across a wide range of corded and cordless drill platforms.

Installation Notes

This drill bit is installed by qualified tradespeople including HVAC technicians, electricians, and sheet metal fabricators using standard drill equipment. Ensure the drill chuck is fully tightened before operation and that workpieces are secured to prevent movement. Use appropriate cutting fluid when drilling harder metals to extend bit life and reduce heat buildup. Always wear eye protection when operating rotary cutting tools.
