I have recently been doing some gunsmithing and building from 80% aluminum receivers.
They are either forged or billet 7075 or 6061 receivers and looking for some recommendations on drill bits that work the best in this type of material.
TiN coated bits were recommended buy a few folks but wanted to get some input on what others have used to drill clean holes in aluminum.
Any info would be greatly appreciated.
