Eagle Cutting Tool 1090D-056-I Self-feed Drill Bit 7/8 in

Product Description

The EAGLE CUTTING TOOL 1090D-056-I is a 7/8-inch self-feed drill bit designed for fast, aggressive boring through wood framing, engineered lumber, and similar structural materials. The self-feed tip pulls the bit into the material without excessive downward pressure, allowing the operator to maintain steady control during high-speed drilling. With a 1/2-inch shank, it seats securely in standard 1/2-inch chuck drills and right-angle drill drivers commonly used in rough-in work. The bit weighs 0.69 pounds, making it easy to handle during extended drilling runs in tight spaces.

This bit is a standard tool for rough-in installations where trades need to bore through studs, joists, plates, and headers. Electricians drilling wire-chase holes, plumbers running drain or supply lines through framing, and HVAC technicians routing flex duct or refrigerant line sets all rely on self-feed bits for this work. The 7/8-inch diameter suits common wire bundle passes and smaller pipe penetrations in residential and light commercial framing.

Key Features

• 7/8-inch cutting diameter for precise, repeatable hole sizing through wood framing
• Self-feed tip draws the bit into the material, reducing operator push force
• 1/2-inch shank is compatible with standard drill chucks and right-angle drivers
• Compact, lightweight design at 0.69 pounds supports use in confined framing cavities
• Suitable for repeated rough-in boring across electrical, plumbing, and HVAC applications

Compatibility

Designed for use in any 1/2-inch chuck corded or cordless drill or right-angle drill driver. No specific model compatibility data was provided for this part.

Installation Notes

Self-feed bits are installed and serviced by electricians, plumbers, and HVAC technicians during rough-in framing work. Confirm the drill chuck is fully tightened before use and that the bit is seated squarely to prevent walking at entry. When boring near structural members, follow applicable local building codes and maintain required edge distances from framing edges per IRC or IBC guidelines. Inspect the bit for wear or damaged feed screw threads before each use to ensure clean, controlled entry.
