Actually, this is a good price that even beats Harbor Freight.

But, if you are by a Menards, their Tool Shop 4-1/2" Turbo Rim Diamond Blade [menards.com] that stays cooler with dry cuts is $3.99 and $3.55 after rebate.

If you want other than made in China, you will pay more.

Unless cutting lengthwise and then use a wet tile saw like the small Ridgid when it is on sale, just use a bottle cutter that uses a common Fletcher glass cutter and score all the way around for the fracture to follow. Heat is your issue with the saw, as you are fracturing the glass, so go kind of slow with a wet blade so as not to have the fracture run out ahead of you that will be random.

Glass is easy enough to cut, but finishing the edges might be your real issue. You could use a belt sander upside down with silica carbide belts, but running dry, you have to be careful with the heat. Start out with a 120, then 220 and then 400. They do make a cork belt for final finish, but a little stick wax on the 400 grit will do well.

Our old glass cutting machine that came from PPG has a brass blade that runs in water that I don't think can be bought today.... but basically a predecessor to the wet tile saw. Our old beveling machine is a heavy steel wheel that turns flat and with water, uses carborundum in different grits. It is quite the art that my Grandfather was good at... a necklace deal with notches that determined the angle of bevel. Our glass grinder is an older Sommer & Maca with a 106" wet belt. Sommer & Maca was bought out by C.R. Lawrence, their long time competitor, that sells most anything you would need.

Like on any 5/8 or 7/8 inch arbored power tool like a portable hand saw or multi tool.

I have a little Worx 4 1/2" circular. Depending on the job might use on that or one of the angle grinders. Definitely easier to make a straight cut with the circular and the associated guides. And I might even make it halfway thru the second cut before it gives up the ghost.

I used one of these on a project earlier this spring. Worked great out of the package but definitely slowed down after not long. Still works but definitely lost a lot of material, probably a one-two job wheel. Obviously price expectations, I was pretty happy.

You need to find a good glass tile blade more than a saw. Glass generally responds better to slower RPMS and doesn't need as much power to cut through (vs hard porcelain) but the speed of the cut is slow as well since glass blade will have very fine grit so it doesn't chip glass but cuts it instead. It also depends on the thickness of the glass tile since thinner pieces tend to chip and crack easier vs thick ones.

I bought one of these last summer, and I have cut SO much limestone with it. Limestone is quite soft, but some of it is quite tough. This sucker has ripped through everything thrown at it, and lasted a long time.

Most of them, or any other circular tool that will accept the 4 1/2" diameter with a 7/8: hole that almost always requires a bushing adapter from the typical 1/2" or 5/8" arbor shaft. Most of the tools come with this bushing adapter, but not all.
