1911 80% Receiver Tooling Bit Kit
Complete Drill bit and end mill cutter kit for completion of an 80% 1911 frame. 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 too big or too 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
