When drilling metal is it better to switch on rotary hammer or just normal spinning drill?
But the progress with normal spin is extremely slow, took me an hour to get like a 2mm indent, and 30 seconds with hammer to get the same thing! (I'm just scared of the loud hammer sounds)
I'm not sure what I'm drilling, but it's a metal door frame. I'm using a cobalt drill bit
Hammer is for concrete. What type of steel is it? Stainless takes longer to drill. Your bit may be dull. Also, try starting with a small bit, then gradually move to the size you need.
