Don't know where to post this but I'll try here.
I always have trouble drilling into this type of situation:
I have a metal door frame which was filled with concrete. I need to drill a hole for a #6 screw to fasten a aluminum framed weatherstrip. I figure using a 3/16" carbide bit in a hammer drill. I have used a 3/16 carbide bit in the past but when I hit rebar, it mushroomed. Would the 3/16" bit take the abuse of drilling through the metal frame and then into the concrete. After the hole is drilled, I figure in dropping in a plastic anchor. Does anyone have a different idea?
I have used a 1/4" carbide bit into metal first then concrete in the past with no problems.
I have no problems drilling into a metal deck with concrete (office building) but the little holes always give me trouble.
To get the terminology out of the way
Self drilling/TEK screw
Self-tapping/sheetmetal screw
Thanks
