Eagle Cutting Tool A700-020-I Hss Aircraft Drill 5/16

Product Description

The EAGLE CUTTING TOOL A700-020-I is a high-speed steel (HSS) aircraft-length drill bit designed for extended-reach drilling in metalworking and aerospace-adjacent fabrication tasks. With a 5/16-inch diameter and a 6-inch overall length (OAL), this bit provides the reach needed to drill through deep sections, structural assemblies, and stacked materials where standard-length bits fall short. HSS construction provides adequate hardness and heat resistance for drilling mild steel, aluminum, and similar materials at typical shop speeds. Machinists, aircraft maintenance technicians, and sheet-metal workers are the primary installers and users of this type of tooling.

Aircraft-length drill bits are specified when access depth or clearance requirements exceed what a jobber-length bit can reach. This bit is suited for structural repair work, automotive fabrication, general metalworking, and any application requiring a longer flute and shank than a standard twist drill. The 6-inch OAL makes it compatible with standard drill chucks on hand drills, drill presses, and magnetic-base drills. It is an import-grade bit appropriate for production use where cost-per-hole efficiency is a priority.

Key Features

• 5/16-inch diameter for common fastener clearance and pilot-hole applications
• 6-inch overall length provides extended reach beyond standard jobber-length bits
• High-speed steel construction offers heat resistance and durability on ferrous and non-ferrous metals
• Aircraft-length geometry suited for deep-section and stacked-material drilling
• Compatible with standard drill chucks — no special tooling required

Compatibility

Designed as an aircraft-length replacement or supplemental drill bit for use in standard 3-jaw drill chucks accepting 5/16-inch shank tooling on hand drills, drill presses, and magnetic-base drills.

Installation Notes

Secure the bit fully in the chuck before operation and verify there is no runout before drilling. Use cutting fluid or lubricant when drilling steel to extend bit life and reduce heat buildup. Clamp workpieces securely to prevent walking or grab, especially when breaking through. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
