In stock and ready to ship.
This kit includes (2) drill bits for drilling the side holes of your 1911 and custom made key cutter and ball end mill bits.
The key cutter bit and ball end mill bit are made so you can get a proper mil-spec depth and height when you cut your rails and barrel seat which is why they had to be custom made. Because all the commercial bits out there are either to big or to small.

(1) .118 Key Seat Cutter (Cuts rails to mil-spec depth and height)
(1) .348 Radius (ball) End Mill Bit
(1) 4mm Drill Bit
