80% Arms Replacement Custom 5/16" End Mill for Easy Jig Gen 2

The custom made 5/16 inch end mill is optimized for high speed precision milling of 80% lower receivers with a handheld router. The upper portion of the end mill is reduced to 1/4 inch to fit standard routers, while the shank and cutting surface are 5/16 diameter to allow for easier milling with minimal deflection.

Notes:

This is the only end mill that will work properly with Easy Jig Gen 2. Using another type or size may cause damage to your jig, voiding the warranty.
