- 2). Secure the 3/4 inch bit into the drill.
- 3). Drill a hole in the center of the hole you drew on the metal.
- 4). Use the tightener tool that comes with the sawzall to loosen the screw that holds the blade in on the top of the sawzall head.
- 5). Slide the torch blade into the sawzall and tighten it into place.
- 6). Insert the blade into the drilled hole. Pull the sawzall trigger and cut down to the circle you drew, and then cut along the drawn circle line.
