Replacement 1/4 End Mill for Easy Jig® Gen 1

The Replacement 1/4 End Mill is a precision solid carbide milling bit custom engineered for the original Easy Jig® Gen 1 milling system. This end mill features a 1/4” diameter and a compact 0.75” flute length, designed specifically to optimize milling performance on 80% lower receivers. Its short flute geometry reduces stress on the jig and receiver, promoting smoother cuts and extended tool life.

Key Features and Specifications

• Diameter: 1/4 inch for compatibility with the Gen 1 Easy Jig® system.

• Flute Length: Short 0.75-inch flute length reduces chatter and increases control during milling.

• Material: Solid carbide construction for superior durability and wear resistance.

• Geometry: Specially designed flute geometry optimized for aluminum and polymer milling, reducing heat and vibration.

• Length: 4 inches overall length allowing deep milling while maintaining stiffness.

• Compatibility: Made exclusively for use with Easy Jig® Gen 1; using other bits risks jig damage and voids warranty.

Usage

The end mill threads directly into compatible handheld routers that work with the Easy Jig® system. It is used to mill milling trigger pockets, fire control cavities, and other precise cuts on 80% AR lowers. Proper cutting fluid and controlled feed rates will extend the end mill’s life and produce high-quality finishes.
