E-Tech Aerospace: Drilling Crowfoot

Features & Benefits of the Most Versatile and Durable Crowfoot Drilling Attachments in the Industry 

Modular Design

Allows for commonality of components across product line. 

Versatile Angled Designs

90 and 100 degree versions – each can index in 30 degree increments through full 360 degrees.

Quick-Change Feature

Switch from pistol style to straight or angle head in seconds.

Superior Output Gear Bearing Design

Extends life up to 5x compared to tools from other manufacturers with more cutter support to reduce heat, improve performance, and 25% less blown holes.

Excellent Ergonomics

Smaller, lightweight design improves maneuverability without sacrificing durability.

Split Housing Design

Allows for strong “I Beam” type construction to minimize deflection under load.

Innovative Stepped Axle

Positive containment of gear axles eliminates axle movement.

Tough Bearing Construction

Superior bearing support for input and idler gears - provides more support for the cutter.
