Eagle Cutting Tool A712-029-I Hss Aircraft Drill 29/64

Product Description

The EAGLE CUTTING TOOL A712-029-I is a high-speed steel (HSS) aircraft extension drill designed for deep-reach drilling applications in metal, wood, and composite materials. With a 29/64 inch diameter and a 12 inch overall length (OAL), this bit provides the extended reach required when standard-length drills cannot access the worksite. HSS construction delivers reliable performance across a range of materials and maintains cutting integrity under typical shop and field conditions. Machinists, aircraft maintenance technicians, and general metalworking trades rely on extended-length drills like this when working in confined or deep-clearance situations.

This drill is suited for use in aerospace maintenance, automotive fabrication, HVAC sheet metal work, and general industrial applications where standard drill lengths fall short. The 29/64 inch diameter is commonly used for hole sizing prior to reaming or for clearance holes in structural assemblies. The 12 inch OAL makes it especially practical for drilling through thick stock, bulkheads, or layered materials in a single pass.

Key Features

• 29/64 inch diameter provides precise sizing for clearance and pre-ream applications
• 12 inch overall length enables deep-reach drilling not possible with jobber-length bits
• High-speed steel (HSS) construction handles metal, wood, and composite substrates
• Aircraft-style extended length design for confined-space and layered-material access
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as a standard shank HSS aircraft extension drill compatible with conventional drill chucks and drilling equipment that accept a 29/64 inch shank diameter.

Installation Notes

Install this bit into a compatible drill chuck and ensure the shank is fully seated and securely tightened before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Always wear eye protection and secure the workpiece before drilling. Follow applicable shop safety standards and equipment manufacturer guidelines for speeds and feeds appropriate to the material being drilled.
