DT-DIATOOL Diamond Core Drill Bits Kit 25/35/51/65/102mm with Diamond Finger Bit 25mm for Tile Marble Granite Stone Vacuum Brazed Hole Saw Kit

I waited b4 submitting a review thinking I might use the same size again soon to see how it performs with multiple uses but haven't yet. I figured a review would be appreciated. I have used 3 different sizes and I must say they get the job done. After the initial 1st use after inspecting them they seem to not have deteriorated much at all. For the price I must say they are well built and perform just the same. I have purchased other sizes aside from what comes in the kit they perform just the same. I tried to attach a video to this review to no avail. I wanted to show the clean cut it makes.

Best I have used. I only gave 4-stars because this does not work well with a drill. It worked great with the grinder and a little pressure. I do recommend getting the sticky drill pads for the size fixture you use to keep the cutter from walking off. Over all pretty good.

Great set of hole cutters, for ceramic tile !! Every tile installer should have a set of these!! Well worth the money, does the job fast, and perfect !!

Ok

Nice tool for DIY , works well , good quality for the money. We drilled some holes thru heavy granite countertops , perfect ! Only thing to mention , "Take your time to drill , no rush and use water guard to cool it" ( dont forget to put a bucked underknee the granit , into the cabinet, to catch the water if you get thru )

Short life of the 3/4” hole saw.

Excellent

These things are so easy to use works great easier to use with a little water. I am a plumber and the one for 2 inch hole will handle a 1 1/2 inch pipe because of outside diameter. I’m going to buy the other ones for 2 inch pipe and 3 inch pipe they work so well
