If it's a small hole 3/4" or 1" I just use a hammer drill. You can do that with bigger holes too just drill more holes. Our if you have access to a core drill ( more expensive ) you can drill exactly what ever size you.

yeah, i use the hammer drill and a small bit now, but i'd like to see a more perfect cut....just curious if anyone has ever seen one of these....my friend had one for plumbing, they probably don't last that long either

You mean making holes on bricks?
I don't know if the "coring machine" used by drillers could be of use. I once rented one, but the hole was drilled down through the bricked flooring! It's a cylinder with diamond cutter/teeth at the drilling tip (looking like the door lock saw). I think the brand is HILTI.
Try googling "coring machine, HILTI".

I concur on the core drill. It's basically a masonry hole-saw. You will need one with a shank that matches your rotary hammer; an SDS-Max for my Bosch.

I mad a 6" hole in an old 3-courses-thick brick wall for a customer. The resultant hole is smooth and round. Rent one, and the drill for it if you don't already have one.

Some of these may be larger than you need, but . . .

Those are diamond bits. These are carbide - the kind I have:

For the bulldog SDS you will want a "Dry core" bit, they have teeth.

The ones in Larry's pictures are "Wet core" bits and require a different tool then a bulldog.

You can use dry core bits in a coring rig.
The bits have slots cut in the sides of the cylinder to cool them.
I have a Diamond Products M4 dry coring rig and the Weka DK13 handheld drill motor that also uses vacuum core bits.
The drill is designed to accept a vacuum where the water would go in.
It sucks the dust through the bit and drill so the drilling is mostly dustless.
Works good inside of buildings where dust can be a problem.
Not so good on concrete, it works best on brick and block.

You can also get a dry core bit to use in a right angle grinder.
You have to be brave to use this setup.

Actually the "somewhat" large size that "Jim" is sharpening would work great for many different jobs. After making your far-oversized hole you can always re-brick the area around whatever items you may need to shove through the hole making this an all inclusive project. It's fun at partys and everyone can enjoy this handy tool. Works great for installing small ponds in your back patio or making portal windows in "Tommy" and "Suzie's" playhouse. Order you super-duper giant oversized bit today.:D:D

really, all that i would want it to fit is 1/2, 3/4, or even 1 LB's and the like...you think lowes or hd would have this? or is this more of a specialty tool?

The ones in the second picture are the dry, percussion type.

I would not use a core bit for 1 1/2 or less.
A good solid hammer drill bit in the bigger sizes lasts me years.
With a big enough hammer drill it normally goes well.
I got some core bits. It was a cheaper set that was still more than $100.
Maybe I got 6 holes out of it.
The teath chip off.
The piolt breaks.
The pilot set screw loosens out.
The hole saw cracks.
The drive breaks.

You need to put the pilot in.
Start the hole.
Remove the pilot.
Hammer loose some of the cored material from the building or saw.

For larger holes with brick we drill with a larger solid bit and knock out 1/2 brick sizes. Not as nice as a core bit.

Any how get a good 1 1/2" spline drive hammer drill and a few good solid bits.

yeah, ive got the bosch bulldog sds...ill try the masonary hole saw

you can buy a whole set of cheap chinese (harbor freight cheesy)
dry bits up to 2 1/2" that'll work in a sds hammer drill.... about $125.
guy on ebay sells them. he's in canadia, 'eh.

hit a piece of rebar, and kiss it goodbye, however.... i drilled 13 holes
thru my pool for the replumbing process... hit rebar on the last hole :-(
they'll work, but they are cheap as dirt.
