What's the deal with masonry core bits?

[SixD9R]

I need to put a 2" hole through a concrete wall and I have an SDS plus rotary hammer. I realize SDS plus is the little dog of rotary hammers but it seems really weird that core bits up to 4-3/8 are available for SDS plus but in 2" the only thing I can find is SDS max. Anybody know of an 2" SDS plus core bit or what the deal is why 2" is only available in SDS max?

For background, I want to run an 1-1/2" PVC pipe which is 1.9" OD through the wall so a 2" hole sounds about right with a little caulking to seal it up.

I've also checked around on other retailer's and am seeing the same as this one.

I'm at the point where I will just rent an SDS max hammer and 2" core bit if I can't find something soon.

Something a lot of masonry guys do is buy dry bits and put them on angle grinders. It's risky and the can will probably walk all over the wall. https://www.amazon.com/Drill-Brick-Concrete-Block-Masonry/dp/B017JO7RUA/ref=sr_1_6?crid=1T0R66ZB009MM&dib=eyJ2IjoiMSJ9.xZmZVvhs_ANMPDndfhWA3Sl7OVKPEli3IMo7qQf5PApFO8riFJn8GJsoP6k-nt3soQRTJEV9fog_ArF4aOeaCT99K120Fxym5sMzGVYSJGhnrQAmyt8aMnNAjOmGATjTgewhg8xzzFzhAwugn-v_BkZk1uH1PY8ESxfhr76V_wtJBppHZcucUGnawfGO9mAxMKom7FWaOw8iglmXVAHIROWuy3zT1zcduErx5goudX7VDYxJH_1Oy_NgIN9LO2HoYvKnZrzKXi0rPAR57T5hE4TpHPjIGTxi9AwRROYBEfI.dJArL9-RXKogNfiHm1RK50Qy2w_cA74sAZI4OfIxstk&dib_tag=se&keywords=2+dry+core+drill+bit&qid=1710087638&sprefix=2+dry+,aps,144&sr=8-6&th=1

If you lived closer. I Have a core drill. I prefer the concord bits but these work good also.

 

[NicPaus]

Hahaha I screen shot one of those for a option.

Was it you that posted pics of drilling through walls and shit

Wasn't me. I don't do it much.

If there's rebar you might encounter, you're going to want to use a Diamond Wet Core.

@jonnyd might be able to give some advice as well

 

[SixD9R]

Thanks for the the replies! As was suggested, I’m in Pa. but appreciate the offers to help!!

I don’t think there is any rebar in the wall. The Amazon suggestion might do the job. Thanks again!

A huuuuuuge shout out and thank you to @Your ad here for the Amazon suggestion. Bought the core bit he suggested and did the job yesterday. I was a little skeptical since it’s Chineseium and I was drilling 8” of solid concrete but, it actually went very well. And, the carbide tips are still looking pretty good. The guide drill didn’t want to stay tight so I removed it once I got in a little way. Sorry I didn’t get a pic of the hole before putting the pipe through it but it looked good.
I’ll follow up with a new thread on the abortion of a project that I’m doing real soon.
Thanks again for the advice boys!
