I have had no problem drilling with Hilti's core bits.
I use the ones specifically for wet cutting thru rebar.
I have used others as well, Its important to use the right diamond cores for the job.
It's more important knowing what your doing. I have done over 500 holes thru reinforced concrete with various machines, take it easy and take it slow,
I hope your using the base for drilling .
by burning, or ruining the bit tells me your doing something wrong.

Oh, and welcome

I'd bet a coffee that a 7/8" rebar cutter will go through rebar faster than a core bit.



Just drill until you hit bar, then toss in the cutter.

:

2000 Holes? I repeat my advice with more emphasis: Call Your Local Coring and Cutting Contractor! Then the only thing you will need is a Sharpie to lay out the locations. ;)

Well, we are talking about concrete and rebar right? These materials are used because they are durable, which by definition means they are not easy to put holes in.
