The patent-pending ReadyMILL is the first and only Router-Ready End Mill which threads directly to your router, eliminating the need for the collet and further stabilizes your end mill bit even more. Please Note: If you will be drilling your trigger pilot hole on a 7075 lower receiver, we highly recommend the use of a drill press. Trying to drill this hole using a hand drill is very difficult given the hardness of 7075 aluminum. If you are using a 6061 lower receiver, you may be able to drill the trigger pilot hole using your hand drill and avoid the need for a drill press, but we still highly recommend the use of a drill press to ensure that your holes are perfectly straight. Please note this Tool Kit is for the Router Jig PRO only. The tooling for the Original 5D Tactical Router Jig can be found here. How easy is it?
