Review: Works great! - Without having the pilot bit in the middle it can be a little hard to get started. I had to use a smaller Harbor freight hole saw just to start once the borehole got 1/8 of an inch deep I switched over to this and I was shocked at how well it worked! It went through brick/mortar and cinderblock like it was nothing. For the price if your just a diy or home owner and your ganna do this only a handful of times you can’t beat it.
Review: Does the job, but won't make a dent on rebar. - Good price for product. I was going thru a 8 inch solid concrete wall. it was doing fine- not water cooled so you have to give it a break every 30 seconds to a minute. but then I hit rebar in the concrete. the rebar stopped the drill cold, it wouldn't make a dent. I ended up having to drill thru the wall with a long concrete drill bit and making it work (was using to install a mini split thru the wall). it did the job, but won't make a dent on rebar. (and I didn't know I had rebar, or where it was in the wall, I could have just gotten unlucky).
