First of all, I'm not a machinist. I'm trying to put a Sig Sauer folding arm brace (for the MPX) on my Uzi pistol using a StormWerkz Stock Adapter Type 2.
To do so, I have to drill a hole in the back of the pistol. I plan to drill and tap the hole to 1/4-20 for the bolt supplied with the stock adapter. I may have enough threads to put a thin nut on the inside of the receiver.
The problem I have encountered is drilling the receiver. What is this metal made of! My drill bit are getting destroyed. I'm using Dewalt cobalt drill bits and cutting fluid.
Any technique pointers or equipment recommendations would be appreciated.
