Default Drilling through sheetmetal and/or firewall

I need to drill a 2 inch hole through either the sheetmetal in my trunk or the firewall in the front of the vehicle.

What type of drill do you recommend for this task. I once saw a video of Steve Meade using a 1-2 inch bit and made the tast look so easy.

on sheet metal, its highly advisable to use a step bit or a ratchet/hydraulic punch driver as to not shear the metal like you could possibly do using a regular hole saw.

i dont think there a step bit made as big as 2 inches, but you never know.

you could prob rent a punch driver from a hardware store, but youd need to drill a pilot hole for the draw stud.

Any reason you dont want to use a bi-metal 2 in hole saw?

The step bit nudels mentioned only goes to 3/4

My guess is OP is using thicker power/ground wire for such a big hole....?

I also have a set of those uni-bits. Can be had for like 20-30 bucks at most hardware stores. Lowes, Home Depot, etc.

Yes you need some sort of power drill to attach the bit.
