DisstonE0104578 1-1/4-Inch RemGrit Carbide Grit Arbored Hole Saws 32mm

I bought this bit in order to bore holes through a rain barrel to use it as a compost tumbler. The material probably isn't what it was meant to bore through as I had to pull back several times to clear bits of plastic from the cutting edge. All things considered I got the holes bored through.

Worked perfectly

I saw somebody else said to keep the bit cool. I didn’t and it snapped after drilling the second hole. Thankfully, two holes was all I needed for my mother’s Moen grab bar. I’m buying a cheaper bit for the next project. Amazon has others for $7-9 instead of the $14 I paid for this one.

Bath tile can be a hard material to work with...it is brittle, easy to chip, and to cut it you simply must use specialized tools. I was installing a Moen grab bar in the master bath and the horizontal bar was half inside the rear shower wall and half outside. Outside was easy, I used a block of birch ply cut 4 1/4" x 4 1/4" on the outside drywall to even up the two mounting surfaces--holes through the birch ply and drywall were made with a standard hole saw at 1 1/4". For the tile I chose to drill it out using this Remgrit carbide hole saw on a "four corner" + in order to have (A) an easy starting spot in the grout and (B) keep the saw relatively even on the four tiles. It worked like a charm. Slowest speed on the drill, just enough to keep removing material and a slow advance did it. I cut off the four tips of the four tiles and had a perfectly smooth and round hole. I would suggest to anyone using this hole saw that they first put masking take over the areas where the cutting will be in order to avoid possible surface chipping--not an issue in my case because the cover plates for the safety bar extended well past the hole I cut. BEAR IN MIND this saw is not meant for other materials including drywall and wood so make sure you FYI before you DIY to make sure you have all the right tools.

I thought tile is tile. Well the shower tile was porcelin and it basically laughed at the drill bit. We had to use a diamond coated bit to drill the tile. The bit does OK on ceramic tile. Verify the tile is ceramic before you buy.

Purchased this hole saw to drill three holes in 1/4" thick ceramic tile to mount a grab bar unit in a clients shower. It worked quite well, and I would surmise it still has quite a bit of life left in it. Here is how we used this to cut holes in the tile.- Mark your center where you want the hole.- Place the tip of the centering drill on your mark and run the drill BACKWARDS for just a couple rotations to dimple the surface of the tile on your marl. If you try to just start drilling, it will likely move off your mark, so start in reverse just to set a dimple in the tile surface.- Have a spray bottle filled with water, and a second set of hands to spray it while you drill. You need to keep a constant flow of water onto the surface while drilling otherwise you will make little progress and you will ruin the hole saw possibly causing you to write a bad review for a product that was simply used incorrectly.- Keep the drill speed somewhat low as you simply cannot power through ceramic tile, and don't forget to keep cool water running on the hole saw while drilling.For the price point I would have been happy enough if it lasted just long enough to drill the three holes I needed to install the grab bar unit, however it still looks like new and I suspect has several holes left in its lifetime.Lastly, we used this hole saw on Ceramic tile, but I have little doubt that it would work equally well on porcelain tile using the same method detailed above.

It works well.

I purchased this to install grab bars into a tile shower. Best constructed shower I've ever seen ha ha Ha. Not only did it have good quality thick square tile, but also had cement backing board behind it. Bough 2 just in case but only needed one to do five Holes. Could've done 20. Great price, fast shipping.Just FYI , plan to use the mounting bracket for each hole. I planned for a four out of five and found I had to go hunt down a fist bracket.

I've seen video clips suggesting drilling a sponge first (and leaving the wet sponge inside the hole saw while drilling). Sounds like it might work, though in the end I didn't do as much water spraying as I expected. Was drilling a hole in an existing tile wall, and I think it would have been worth first drilling a pilot hole with a very pointy tile hole saw, then using this one and its built-in centre drill. As it was, the centre drill wasn't very sharp/pointy and tended to wander while trying to start the hole. In the end I did get the grab bar up which is what mattered.

Worked great through brick.
