3/8 inch Diamond Hole Saw, Wet use, 3/8" Diamond Drill Bit for Porcelain Tile Glass Granite Ceramic Marble Stone, 10mm Tile Bits x 2 Pack (1/4" Hex Shank)

Wasn’t sure how this would work, being such a cheap price. To my surprise this cut a perfect clean hole through the tile was very impressed.

Great price for a quality tool. Effectively cut hole without breakout of stone. Nice product!

happy to report that this tool worked great to enlarge hole through 8" foundation wall successfully. removed center bit since already had 1" hole, shank of 3'8" requires 3/8" minimum drill, slow speed worked best stopping to water mist cool bit after 45 seconds or so, took approx. 10 minutes of going slow and easy from each side of my wall to get joyous relief to be able to pull through my new larger diameter water line.

Bought this to cut holes through tile and decking for a 4 hole faucet set.Great price and good enough to get the job done. Pretty much used up by the last cut.Smooth cut through porcelain tile with no chipping. Underlying support material was probably the cause of early failure.

Was wondering how well these would do for cutting through ceramic tile. Answer: GREAT!TIP: go slow & have a container of water to constantly dip the hole saw in to keep it wet while cutting (acts as lubricant and washes residue from cutting off the hole saw while cutting)

Let's face it - this is a huge hole! I was a bit skeptical at first but for the price, I didn't have much to lose. My project was on an existing tile wall and the cut spanned two tiles. I also had to cut through the backer board. Since it was on an existing wall, my lovely assistant kept up a steady stream of water from a spray bottle and the cut went surprising quick. Hansgrohe recommends a 127mm hole but the 3 extra millimeters made installation easier I think - especially for remodeling work. I rated durability as 5 stars, but honestly, I only intended to use this once and didn't really care. Though after rinsing it off, as you can see in the first picture, it looks brand new. I think there's definitely more life in it. Just take it easy, go slow and keep up a good flow of water.

I used these bits to get through wall and floor tile to install a shower door, I was able to just use one of the two pack. Well made and left a very clean hole.

Great value hole saw for drilling through tile and cement board. Used this hole saw to drill holes for Moen Secure Mount Anchors.

We used this diamond drill bit to cut porcelain tile and it worked like charm

It work very nice. With a bit in the center it work really easy. Usually I have a couple of hole saw without a bit in the center but that one work perfectly. Same as the other, you have to use water with it.

At first I wasn't very convinced how good it could be, but after using it, the cut was very fast and smooth. When I finished I checked the diamond on the blade and it was intact, I don't know how much more I will be able to use it, but so far it served its purpose. Thanks

I used this drill of 25mm to make a hole of 25 mm in a wall with tiles.The drill was working perfect, in no time I get a nive hole of precisly 25 mm.

Great buy. Served its service.
