Not for the pro.
These are inexpensive bits that are great for punching a hole or two, but certainly not for repeated use. I cut a hole through a piece of moderately thick ceramic tile, flooding the cut with water and running at a slow drill speed without any problem. That bit may have one more hole left in it if I'm lucky. It's pretty much worn out after the one cut, but it got the job done. Bear in mind you get five bits for a very reasonable cost so I give them four stars based on value. They're good for keeping around in case you need to drill the odd hole. If you plan on drilling a lot of holes though, these aren't what you want.

Really cheap. Decent in a pinch?
Got the metric set, not the us standard. Not the end of the world since I was just looking to poke holes, sizes were approximate anyway. I used the 35 mil saw on a thick piece and it melted before I got through. Literally melted and curled back. Honestly, a bit was probably user error. Smaller sizes worked as expected.

5 holes and still in good condition. These hole saws will require a guide ...
Worked as expected on ceramic tile. I used the 1-1/4", 5 holes and still in good condition. These hole saws will require a guide to keep them from wandering. I drilled out the correct size hole on a piece of aluminum then clamped "gently" to the tile. Keep wet for cooling, should last for 10 or more holes.

Good enough for a few cuts. But, if that is all you need, these work just fine.

Good price. Don't expect it to stay sharp for to long though.

Good value for the price if you only need to make a few cuts through stone
Used for cutting limestone. They worked well for this, but near the end it was clear the bit i was using was wearing out quickly. This was only after cutting through approx 6in of limestone.

how do you like an lack
A hole is an absence...how do you like an lack? These removed circular portions of tile pretty much exactly where I wanted them to.

A little more information needed.
Perfectly functional, but sizes are not marked on the actual tool. I had to use my micrometer to find the correct size.
