Eagle Cutting Tool A700-016-I Hss Aircraft Drill Bit

Product Description

The EAGLE CUTTING TOOL A700-016-I is a high-speed steel (HSS) aircraft extension drill bit engineered for deep-reach drilling in demanding trade and industrial applications. At 0.25 inch in diameter and 6 inches overall length (OAL), this bit provides the extended reach needed to bore through structural materials in tight or obstructed access points. HSS construction delivers the hardness and heat resistance required for repetitive use in metal, wood, and composite materials. It is a standard tool for aviation maintenance, HVAC installation, plumbing rough-in, and general mechanical trade work.

This aircraft-length drill bit is suited for applications where a standard-length bit cannot reach the work surface. Common use cases include drilling through wall cavities, framing members, and structural panels during mechanical system installations. The 6-inch OAL makes it practical for electricians, plumbers, and HVAC technicians who regularly drill through framing and sheathing from a single-sided access point. The 0.25 inch diameter is a widely used size for pilot holes, wire and pipe pass-throughs, and anchor point preparation.

Key Features

• High-speed steel (HSS) construction for hardness and heat resistance during extended use
• 0.25 inch diameter — a standard size for pilot holes and mechanical trade pass-throughs
• 6 inch overall length provides deep-reach access in confined or obstructed work areas
• Aircraft-length design suited for single-sided drilling through structural assemblies
• Minimum order quantity of 1 — available as a single unit for spot replacement or fleet stocking

Compatibility

Designed as a standard 0.25 inch shank aircraft-length drill bit compatible with corded and cordless drills and drill presses accepting a 0.25 inch round shank.

Installation Notes

This bit is installed and operated by tradespeople including electricians, plumbers, HVAC technicians, and general mechanics. Secure the workpiece before drilling and use appropriate speed settings for the material being drilled — lower RPM for thicker metals and higher RPM for wood and composites. Wear eye protection and ensure the drill chuck is fully tightened before operation. Inspect the cutting edge before each use and replace the bit if the tip shows signs of wear, chipping, or heat discoloration.
