Tile Hole Saw, EVERMARKET 15 Pcs Diamond Holesaw Drill Bit Extractor Remover Tools for Glass, Porcelain, Ceramic, Granite Stone Drill Bits 6-50mm

Worked great for drilling a hole through a quartz countertop (1.20"). The maximum cutting depth is 1.17" for the 40mm bit, so a light tap popped out the quartz plug (see pic). FYI, I taped a cutout from a plastic milk container to the counter to control water during the work (see pic). I used the tip-the-drill method to start the hole, which worked well.

They are good but not sure how long they will last/holdup? I used the small bit And most of the “diamond” is gone

Bought these to install some tiles in a shower, where the handles are. Worked very well. Just be sure to keep them wet while grinding away. One of the larger ones bent as I was angling the cut, but I was able to bend it back enough to get the job done.

Did the job. Hard to get started since there is no center point to hold in place, walks across the tile. I took a scrap piece of tile and drilled a hole into it then had my boyfriend hold that piece on top of the tile I needed to cut to prevent it from walking and not cutting where I needed it to. Since I only had two holes to cut for the tub fixtures, these bits worked out fine.

I just got done cutting the two holes I needed done. I cut through porcelain with no issues. Made a wooden template with a wood hole saw, just oversize. Screwed the template over the tile into a work surface. Flooded the hole with sprayed water. Did the angle cut to start, then squared it up and drilled with little pressure and a slight rocking motion. I was apprehensive at first, but the two holes of two different sizes cut like butter. Patience equals great results!

used to drill holes in stained glass projects and wine bottles for wind chimes

Overall product looks Good when you take it out of the package, however that's the end of the positive I can give for thisYes it is 1/10 the price of a real set of tile hole saws but it's definitely not worth the frustration you will encounter while using these, especially on higher grade tile like porcelainThe first initial hole that was made actually went well. No issues. However, I noticed that upon making one hole that a large portion of the jagged edges on the bit were no longer thereFollowed instructions is exactly as it should have been kept the tile but after the first hole the tile but was so smooth it literally was as smooth as the tile and wouldn't cut anythingOne time use. These are probably fine but nothing moreOverall very disappointed with these bits even at $15 for all of them they are worthless if they don't work

Had to drill a couple holes through a marble counter top. Worked fine using a few spritzes of water. Probably wouldn't hold up for dozens of holes but for one-offs they are fine. Would buy again if I had to.

It can be risky drilling drain holes in ceramic plant pots as they are so brittle. A better method is to use hole saws such as these. I started off by fitting a mid sized hole saw in my cordless electric drill and making a dent in the porcelain by holding the drill at an angle then slowly bringing the drill to the vertiical. There is a helpful video on YouTube which gave me the method. The saw worked fine on two pots.

Wont last for ever, but will do for DIY projects - where you probably won't use them again!Bit fiddly to get started without any 'centre' drill, but found bracing against knee/leg and letting it cut upwards was easier than trying to get the downward side to cut (as that slipped all over the place).

Very good quality, robust easy to use clearly marked with sizes. Good value delivered timely PERFECT

Rust on the goods

For the price you cannot go wrong! These work well and you get a set of sizes so I pressumed they would be one use and chuck but they seem to keep working!! Takes a bit of skill to start with but great value.
