SHDIATOOL 1-3/4 Inch Diamond Core Drill Bit for Porcelain, Ceramic Tile, Marble, Brick – Vacuum Brazed Hole Saw, 45mm, 5/8-11 Thread, Wet/Dry Drilling

Summary: Adding a few grab bars to dad's shower. I used a lot of products for this project, so including all related products in this review. Recommendation: 1) When mounting grab bars, it's always easier if you can find the stud to attach to. In this vertical install, I decided to use a stud and Wing-Its anchors; partially because I wasn't sure I could hit both, and didn't want to put two fasteners vertically (on either the right or left only), but that would also position the bar in the shower a little too far in (towards the shower control). 2) The WingIts requires a 3/4" hole through the mounting material. For tile, this can be especially challenging. I used the SHDIATOOL diamond 3/4" bit, with the DRILLAX adapter to get through the tile, and then used the 3/4" BOSCH bit to finish through the dry wall. Also used the BOSCH bits for the other small hole. Having the right tool for the job is the difference between project completion, and a messy, disaster.

These core drills worked great. I cut holes for studs in some granite slabs being attached to the front of my house to mount lights and an address to. It’s a bit of a hassle removing and plunging out the cores after each hole cut but I tried using a couple other methods which resulted in destroying the slabs. For my application, these were exactly what I needed. I ended up reaming out the wax material as it seemed to make the bit clog up more and make it difficult to get the cores out. I was able to use water instead for my project.

This bit is by far the longest lasting that I’ve ever used. I spray a ‘zep professional spray bottle’ onto the bit as I cut to extend the life of the bit and this bit is on hole #142. I probably did about 120 holes through ceramic and block and 22 holes through porcelain and block. SEE PHOTOS ATTACHED OF THE BIT AFTER 142 holes! It’s likely going to snap soon as the thickness of the bore is shaved down after so many passes that the 1/4 shank can’t hold anymore. But you can see the diamonds on the bit look nearly new!!! Even on the tip!

This worked quickly for my brickwork. I am installing a high efficiency furnace that requires 2" nominal PVC pipe. Outside pipe measurement is 2 3/8" diameter. The 2.5" hole saw worked perfectly and made clean cuts through the brick. I had to stop half way and hit the brick with a chisel to crack off the end allowing the bit to get deeper into the brick. However, it had no issues picking up where it left off and grinding out the brick. I used a 4amp angle grinder -- this bit attaches directly to a standard angle grinder bit. 4amps worked good for my purposes -- 2 holes. However, with pressure the 4amp slowed down at times. I think a higher amperage angle grinder would drill through a solid brick in 2-5 minutes easily. Great for jobs around the house.

I am happy with the product normally and it did its job. However, when you use it with water, dust from the drilled hole become solid and stuck inside of the item. Taking out that piece took longer than drilling. Side hole was not enough to take that solid dust part from inside. Unfortunately, I had to go to nearby store and purchase more expensive Milwaukee brand. It seems more weak but did better job.

This hole saw chews through tile like it’s butter. It made easy work of a hood vent install when the wall was tile and drywall.

Good tool,easy cut.

It would not thread completely into a standard hole saw mandrel (2nd pic) Made it about half way and it locked down like the thread pitch was off. Put it in a vice and locked it down w a wrench. Sacrificed a mandrel for it, no biggie. Start real slow and angled till u get a groove then straighten up. Worked good and was 1/3 the price of one at Lowe’s and HD. The granite core stayed stock in bit so I either have to figure out how to beat it out or it’s a one and done bit. If I have more than one hole to do keep that in mind. Would buy it again.

Es buena atravesó rápido el granito

Does what it says cut 2 holes through 1 1/4” thick firebrick. Cut was clean but did have to applied some pressure to get through. Cutting speed was about a minute to get through the material. Lots of diamond grit still on hole-saw after the 2 hole. I believe it will last a bit longer. Function like the description said and it was a fair price.

Muy mal el material de la broca, solo aguanto dos cortes y se rompió, y Amazon no tiene garantías

This works very well, it’s quick and clean. Will be buying more soon

Wow ça perce la porcelaine à merveille !
