Eagle Cutting Tool AC712-024-I Cobalt Aircraft Drill

Product Description

The EAGLE CUTTING TOOL AC712-024-I is a cobalt aircraft drill designed for extended-reach drilling applications in metal fabrication, aerospace maintenance, and structural work. Built from high-speed cobalt steel, this drill bit delivers superior heat resistance and edge retention when cutting through hard metals, stainless steel, and tough alloys. With a 3/8 inch diameter and a 12 inch overall length, it reaches into deep cavities, tight bores, and structural members where standard-length drills cannot. Licensed tradespeople and skilled fabricators rely on this style of bit for work that demands consistent performance under friction and heat.

Aircraft-extension drills like the AC712-024-I are commonly used in aviation maintenance, HVAC sheet metal work, structural steel fabrication, and general industrial applications where a standard drill bit lacks the reach needed to complete the bore. The 12 inch overall length provides clearance to drill through thick structural members, ductwork flanges, and framing components without repositioning the workpiece. This bit is suited for use in hand-held drills, drill presses, and right-angle drill attachments.

Key Features

• Cobalt construction provides high heat resistance and extended tool life in hard-metal drilling
• 3/8 inch diameter suits common structural and sheet metal hole sizes
• 12 inch overall length enables extended-reach access in confined or deep workspaces
• Aircraft-style geometry designed for straight, clean entry in metal substrates
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as an extended-reach cobalt drill bit compatible with standard 3/8 inch chuck drills, drill presses, and right-angle drill drivers used in metal fabrication and maintenance applications.

Installation Notes

This drill bit is installed and used by machinists, sheet metal workers, HVAC technicians, and maintenance tradespeople. Always secure the workpiece before drilling and use appropriate cutting fluid or lubricant when boring through hard metals to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed. Follow applicable shop safety standards and wear appropriate eye protection during operation.
