In one package, we have all the drill bits and taps you will need to complete the “80% receiver” blank we sell. The drill bits are imported and are of sufficent quality to complete one or more 80% ALUMINUM receivers. However, if you are going to complete multiple receivers or a stainless “80 receiver”, it is recommended to use high quality bits and taps.
This Economy Tooling Package contains one each of the following:
11/16 Drill Bit (barrel hole)
#16 Drill Bit (12-24 tap drill)
1/4″ Stub Drill Bit (buffer hole)
1/8″ x 8″ Long Drill Bit (op rod detent)
3/16″ Drill Bit (trigger pack holes)
12-24 tap (thread V-Block holes and stock attachment hole)
CAUTION: The drill fixture to complete the “80% receiver” (available separately) is hardened to ensure its accuracy for multiple “drill through” uses. However, since it is hardened steel, you must ensure that each drill bit is exactly lined up with your fixture holes (especially for the barrel hole) if you intend to drill through the fixture to complete the receiver. If the drill bit catches on the drilling fixture due to any misalignment or runout in the drill press spindle, its possible that you will either chip or break the drill bit or will damage the fixture. Accurate, precise alignment is required. Damaged tooling (drill bits, taps etc) will not be replaced after they have been used. Please advise if you have a defective drill bit PRIOR to use.
