Drilling holes for MaxJax

[robertearl]

I am about to drill the holes for my MaxJax and wanted to know how to miss the rebar in the floor. With my luck, I will start drilling right where two pieces of rebar hit so that 4 of the five holes will be centered on a piece of rebar.

If you hit a piece, can you drill the rebar out with a regular drill and go on, or do you just move to a new location and start over.

Do you just use blind luck and hope you don't hit any.

Do you get a metal detector and mark where it is??

I just don't want a lot of holes in my new epoxy floor.

Maybe a stud finder might work.
I have used Hilti drills and bits and they will drill through rebar fairly easily.
A Dewalt or Bosch drill is a toy by comparison.

I used a metal detector, and still just nicked a rebar, and I couldn't drill through it, so had to re do all of the holes. Had I hit the rebar straight on, I probably could have drilled through it, but becasue I only caught the edge, the bit kept slipping off

I hit the side of a rebar in one hole. The Bosh bit would just bind and not go any further. A Lenox hole saw cut it like butter.

A divining rod ? There's a smart axx in every crowd ...........

they make a rebar cutter for SDS rotary hammers. When you hit rebar you swap your drill bit out for the rebar cutter, cut through the rebar, then swap back to the drill bit.

Here is one example http://www.driltec.com/2006catalog/driltec_06catalog_pg06.htm

Well after finding the bits that would drill through the rebar, I went for it. On the forth hole, smoke appeared on my 1/2 inch Rigid hammer impact and it died. After all that worry about hitting the rebar I never thought that the drill would burn up.
