Product Overview

Use the Milwaukee 4 in. Bi-Metal Hole Saw to cut holes in a variety of materials. The steel hole saw can drill almost 2 in. D. Milwaukee Ice Hardened products utilize a proprietary cryogenic hardening process that improves upon traditional heat treat processes. Unlike surface coatings that wear away, cryogenics harden to the core by minimizing soft metal (austenite) and creating more hard metal (Marten site). The result is a product that is more consistently hard throughout, resulting in life up to 50% longer than the competition.

Answer: 
The best way to cut ceramic tile is with a carbide tipped or diamond impregnated hole saw.

The best way to cut ceramic tile is with a carbide tipped or diamond impregnated hole saw.
The type of tile will be the deciding factor. There are two basic types of tile soft biscuit tile for walls and counters usually up to 8x8 tile then there are the hard biscuit or vitrified tile that will need to be cut with a diamond saw and coolant as they are hard to cut and easy to break due to the tile being brittle. This is before you mount the tile to a surface as you need to drill your hole from the back side of the tile. Once it is mounted you will have to drill from the front and anything that can go wrong probably will.
I hope this will help with your project.

Answer: 
The big problem when cutting tile is heat buildup. You have to cool the blade, commonly with water. So, part of the question is, Are you working on a perpendicular surface, like your shower? If so, this is going to be a difficult cut. If you could lay it down flat so you could cool the blade, you might have success.
P.S. I have cut a bunch of tile. Not for the squeamish. Much easier to cut wood.

Answer: 
No this hole saw will not. You need to get the carbide tip hole saws. A tile saw would be the easiest if possible.

I drilled through wood, foam insulation, plastic siding. I think it would cut through ceramic tile if it could bite on that slick of surface.

Answer: 
You'll need the bit and the center that goes with that outer bit in the size you need. The center simply screws together and then the back of the center slides forward into the two holes,you may have to turn the big part of the bit to line up with the two holes. Once it's locked in, install in 3/8" chucked drill or 1/2"
Chucked drill. The smaller drill will have a harder time turning bit if it's a 4"

Chucked drill. The smaller drill will have a harder time turning bit if it's a 4" like mine. A smaller bit won't take as much effort. You won't need any other items for this bit to your drill

You need the hole saw arbor. It's the same aisle, right next to the hole saws. It's around $15.

Answer: 
It's tough enough to cut through brick, however you will need either a deeper saw depth or go as deep as you can then chisel out center and drill again. It will not get you all the way through the brick in one run.

Answer: 
I believe it's tough enough to do it although it's use is not for masonry. Take it slow on speed and let the bit cool. I recommend putting a light amount of water on the bit as you go to help cool and clean out as you go. This though can be any electrical hazard if using a plug in drill. Be aware of that should you choose this direction.
