Re: What's a "Forstner" drill bit?
I use forstner bits all the time when I build stair systems. As others have stated, they are for drilling holes in wood and are 10x better than using a paddle pit when you are shooting for a certain depth. Plus, they are very accurate. I use 1 1/2” bits and put a 1 1/2” plug in and give it a light tap and it’s almost flush. Paddle bits suck for doing finish work.
They will work great on aluminum at a very slow speed and use oil to prevent galling.
