I have a D25213k – Dewalt 8am 2.5ft pound rotary hammer – and the spec rates it at a max drilling capacity of 3″ for a thin wall core bit.
I have some diamond core bits but I don’t know if they would qualify as thin walled – how thin is thin?. I want to drill at 2.5″ hole through a 8″ concrete wall.
If I entered from both sides using the pilot I’d be at 6″ of the 8″.
Do I need a more powerful drill or will my drill be able to handle the occasional drilling of this sort of hole? How do they determine the max drilling capacity? Where does the problem lie in going beyond the max, is it the strain on the motor?
