Masonry Hole Saws

JamesNLA

Anyone know a good site to buy these from? NONE of my supply houses I use have them, neither does the tool stores. I need basically all the sizes from 1/2" to 6" incremental by 1/4"....I know, it's going to cost a bloody fortune but I still need them. Thx

Hole saws or core bits?

For hole saws, I recommend RemGrit hole saws, from Remmington. Greenlee makes them now, and you should be able to get them at your electrical supply house.

For core bits, I happen to like Milwaukee's thinwall core bits an aweful lot.

Try Milwaukee and Hilti?

Just happend to think... you're not inquiring about them for use in granite counter tops, are you? That's a horse of another color. Diamond, to be exact.

Good God no, I gotta counter top guy for that crap. This is mainly for bringing different sized pipes through stucco walls....sometimes block wall / brick. The issue I have is the inserts I use to protect the pipe have different hole dimentions and even though it's the same size pipe different manufactures of the sleeves make the drilled hole size different. I like perfect holes when I am chewing up someones walls. Makes for a cleaner install!!

In that case, I'd definitely get you whatever sizes of thinwall core bits you need. They spawl out less than the regular thickwall bits.

The RemGrit hole saws wouldn't be much good on stucco, unless it's just EFIS. I don't do much stucco, but the thinwall core bits do chew through the wire lath pretty well.

Tried Hilti...nada

Haven't seen a good selection of Milwaukee in person.

Lenox, I thought I saw one on their website a while back...but have never seen one in a shop.

Hmmm, that's like 8-10 K for bits for all the sizes I want. That ain't hapanin. Those are all diamond bits. I was looking for the carbide hole saw bits because they are much less money and I am pretty hard on them. My experience with dry diamond core bits is they burn down much faster than wet cutting. These are just 1" stucco faced walls. I have seen the thin ones like you mentioned and they are butter to go through. Even with the older lath and chicken wire the carbide bits do well for that. It takes me about 10-20 seconds to blow a hole depending on which drill I am using that day.

Maybe I'll do the core bits on the most commonly used sizes....just a bit pricy. I'd have to go through 4 of the carbide saws to add up to one of the price of the core bit.

Hilti has both thin wall dry core bits and regular dry core bits.

NOOOOOO!!!!!!!!! Not diamond!! They just have carbide teeth.

There are a few options.
1.Use the pictured hole saws in a corded 1/2" drill.
2.Use a carbide tipped SDS Max core bit. These are percussion bits that usually will blow out the back of a block. Not cheap, but if it is all unreinforced block you should get a while out of them.
3.Dry diamond bit with a 5/8x11 adapter to put it in a corded 1/2 drill
4.Dry bit on a grinder with a 5/8x11 thread (hang on tight)
5.Wet or dry coring with the appropriate core drill and diamond bits.
