Anthony EsparzaAnthony Esparza: I will not be using these on a regular basis. I needed to drill a hole in my counter top for a water thingy. Figured for the price, just get the set.
I attached the drill to my MilSuckee drill and easily drilled through. I took my time and dipped just the tip in water to keep the bit cool. Something tells me I could have just turned it up to 11 and drilled her right out, but I like to take my time.

The plastic suction cup holder in place thingy was not used. The width of it made it impossible to keep my hole in line with my existing faucet, and we can’t have that.

Nice, clean hole and the bit remained intact afterward. Definitely would recommend this set.

Christina Morgan: I've used this jig and blades quite a bit now, and once you learn that some duct tape opposite the suction cup to keep the jig in place its money well spent. The abrasive hole saw blades work just as well as high dollar, name brand blades do.

Ms.Terry RyderMs.Terry Ryder: I bought this to put in 4 anchor screws with sleeves for mounting a new Toto toilet's little mounting blocks onto porcelain slate tiles over lt.wt. concrete. The holes needed to be exact per the provided template.
The orange guide would not stick to the cleaned tile since the suction cup's center only lifts a tiny little bit and so has minimal suction. Wet, dry, cleaned with alcohol, etc. made no difference. There was no way to adjust it, so it is a defective design. A simple flick of a pinky finger would move the guide over. It was also hard to hold in place manually since the lever handle is right where one has to lean, and so it is painful on the hand and wrist bones. So it was worthless.
...Any sort of sturdy L-angle would have worked equally or better in getting the bit started instead of skipping along the top.
After the first hole, the drill bits took about a minute to go through the 1/4" thick porcelain tile with a 20V drill on the low setting. Two holes ended up off by 2mm due to the guide's shifting, and the bits do not have enough diamond grit on the sides to 'shave' the hole over to the correct location, and were too short to set the plastic sleeve, so I had...

Daniel Couture: Pour perforer tuile

Cliente de Amazon: Funcionó muy bien para realizar orificios en cuarzo (mármol sintético), para la colocación de llaves de agua en la cubierta de una cocina. El soporte para evitar que la broca se desplace también es excelente ayuda. Solo hay que tener cuidado en tener la broca bien refrigerada con el uso de agua constante al realizar las perforaciones y mantener las revoluciones del taladro a una velocidad media.
