Re: Drilling into concrete ceiling

said by Juggernaut:

I was using Bosch bits into pre-stressed concrete and it chewed them like gum.

Visualize at the top of a 40' wooden extension ladder drilling into a pre-stressed concrete ceiling to mount Kindorf hangers for 6" galvanized conduit.

Milwaukee 1-1/2 in. SDS Max Rotary Hammer Kit

I was using a Bosch hammer drill, and the bits were pounded flat. I can relate. It wasn't 40' up though. That's ugly.
