Eagle Cutting Tool AC712-014-I Cobalt Aircraft Drill Bit

Product Description

The EAGLE CUTTING TOOL AC712-014-I is a cobalt aircraft-length drill bit designed for drilling through hard metals and thick materials where standard-length bits cannot reach. Measuring 7/32 inch in diameter and 12 inches in overall length, this bit provides the extended reach required for deep-hole drilling in structural and mechanical applications. The cobalt steel construction delivers heat resistance and edge retention when cutting through stainless steel, cast iron, and other abrasive alloys. Electricians, HVAC technicians, pipefitters, and general trade professionals rely on aircraft-length bits like this for routing through framing, equipment housings, and assemblies where a standard jobber-length bit falls short.

This drill bit is suited for use in residential and commercial trade applications where extended-reach drilling is required. Typical scenarios include drilling through metal studs, ductwork flanges, thick brackets, or equipment panels. The 7/32 inch diameter is a common size for pilot holes, conduit anchors, and fastener clearance holes across HVAC, electrical, and plumbing rough-in work. It is compatible with standard 3-jaw drill chucks and magnetic drill press adapters that accept round shanks.

Key Features

• Cobalt steel construction for improved heat resistance and durability when drilling hard metals
• Aircraft length at 12 inches for deep-hole and extended-reach drilling applications
• 7/32 inch diameter suitable for pilot holes and fastener clearance in trade work
• Fits standard 3-jaw drill chucks — no special tooling required
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed for use with standard corded and cordless drills and drill presses fitted with 3-jaw chucks that accept round-shank bits. Suitable for drilling steel, stainless steel, cast iron, and similar hard materials.

Installation Notes

Install this bit in a properly sized drill chuck and tighten securely before operation. Use cutting fluid or lubricant when drilling hard metals to extend bit life and reduce heat buildup. Wear appropriate eye protection and secure the workpiece before drilling. Cobalt bits are brittle relative to standard high-speed steel — avoid lateral force or prying during use to prevent breakage.
