The Juggernaut Drills and Cuts for You

The Juggernaut Jig is perfect for beginners and pros alike. The include top plate templates act as guides for your drill bits and end mill bits while you make your pilot holes and cut, so there are no advanced calculations to make. The Juggernaut Jig works with any mill or drill press. All you need is a basic depth gauge and the jig does the rest! Since drill presses aren’t designed for milling, the Juggernaut includes a pilot hole top plate. This top plate removes most aluminum inside the fire control cavity using vertically drilled holes. What little aluminum shavings remain can then be safely milled with your drill press in a few moments, without damaging the press or your bit chuck.
