Cutting D-shaped and double flat holes


I didn't see any sub-forums on fabrication so I will ask here.

How do you go about cutting the D-shaped and double flat holes in your home shops? The dremel tool method is getting old fast (faster than I can cut them LOL).

If you go with the greenly dies, invest in an cordless impact driver (I have the Milwaukee 18v brushless) Pops a perfect d-shaped hole.

gophert never thought about that. I do own a manual impact tool somewhere that you hit with a hammer. I do have a 20 ft-lb Bosch demolition hammer, but not a hammer drill - yet.
