Worked perfectly
I bought this to drill holes on a soap dish to prevent water from puddling. Worked perfectly. I poured water in the dish and started at a 45 deg angle and then went up to 90 deg while rocking side to side. The hardest part was to get it to stay in one place at the start. I held the drill bit end in one hand and used the the other hand to power the driver which helped stabilize it. Also, I drilled at low speeds (like a 5 or something on my Dewalt). Also dipped the tip in water after each hole. Came out perfect for my purpose. Only dislike is the red coating comes off instantly so it should've been left un-painted at the tip.

    Awesome for Fireclay Sink
    I used this bit for a reverse osmosis faucet to add on to our fireclay sink. I cut the hole before the sink install. It worked like a charm. I sprayed some water a couple times and cleared out some of the debris as it cut. It cut through about 5/8" very smoothly. The hardest part was seating the cut at the very beginning, but if you start at a 45 degree angle like the video suggests then you should be good. I rotated it like the video showed as well. I would definitely purchase this and use it again if I ever had a need.

      Purchased the 3/16th and it was easy to use to cut through ceramic stoneware. Used some water while drilling and it worked like a charm.

        Does not last at all
        Bought it to drill porcelain tiles. Tested on ceramic, drilled one hole then used my regular drill bit to save it for the real job. Can't finish a porcelain tile, half way through. Water and circular motion don't help.

          drilled one hole and that's it
          i used it to drill one hole in a ceramic tile. It went through ok. Then not so good the second hole. I just used a masonry drill bit to finish. Then I used it to drill a hole in a porcelain tile, it won't go through at all. I have been using water and slow and patient, still no good. I don't know what's with it.

            Excellent Hole Saw for concrete!
            I Cut Through 3' concrete in two different locations. The hole saw seemed to do an excellent job and cut a nice clean hole. It does not have a pilot bit in the center, so I cut a 1" hole in a board to use as my Gide. I clamped the board in place, & the hole saw was slow, but steady and clean. I did add a little water to help with the cutting. I wold deffinatly recumbent this hole saw for concrete or tile, possibly granite.

                Awesome bit to use on tiles
                I actually made 42 tile holes with 1(one) bit. I installed 5 ( each bar needs 6 holes) ADA shower bars plus 2 tilt up handicapped toilet bars( each needs 6 holes). The secret was to cool the bit very OFTEN (I just dunked it in cold water from time to time and go easy on it so it won t overheat. Also, I cleaned the mud accumulation with a steel wire and later with just the right size nail. The red paint is off almost completely but the abrasive part is still in great shape. Because I have another project almost identical, I bought another bit from HD ( saw a price increase in a few months) but if the old one will still deliver performance I will go for it first. Great product with great result. Buy it, you won t regret

                  This is a “must-have” for drilling porcelain tiles! I installed a frameless glass shower door which required 1/4" holes for the hinges. I’ve got plenty of experience drilling holes, including in masonry, but this was the first time in porcelain. Regular carbide tipped drill bits won’t work, or at best will burn out quickly. The “Milwaukee 1/4 in. Diamond Plus Hole Saw W/ Arbor” is the answer. I was skeptical at first. It’s more expensive than masonry bits. And it’s not pointy like a drill bit. Instead it’s a small cylinder with diamonds fused to the round tip. How do you even get the hole started? It’s actually not difficult, but completely different than regular drilling. Here’s what I did: - Go slowly - Get a spray bottle full of water - Set the drill on the lowest speed setting - Hold the Hole Saw at a 45 degree angle and very gently touch it to the tile - If you push hard it will skitter across the surface - As it spins (again, slowly!) it begins to etch the surface of the tile until there’s a groove - Continuing to spin the drill slowly, slowly tilting it to 90 degrees - Now you’ll have a shallow, round cut which makes it a lot easier to keep the drill straight - Begin spraying the hole with water as you continue drilling - You can spin the drill a bit faster now, but not still slower than you would a regular bit - Oscillate the bit as you go (roll it around in the hole) - Be patient. Did I mention to go slowly? ;) - Keep it wet - this preserves the life of the bit - Stop frequently to clean the grit from the hole and the bit - It gets easier with practice It took me about 10 minutes per hole in 3/8" thick porcelain tile, but after 6 holes it’s still cutting at the same speed. I don’t know how many it’s capable of, but it can definitely do more. To preserve its life I switched to a regular masonry bit once I was through the porcelain and into the mortar and backer board. Highly recommended. Model # 49-56-0505

                    Best drill bit for drilling tile. I had thin geometric tile I really was concerned about cracking or breaking. most mortar drill bits chatter and can break tile....this has a diamond round head that gently cuts through. The only caveat I make is that I made a jig of scrap wood with two pieces of sticky carpet pads cut from the carpet squares to press against wall. drilled a hole through the scrap wood to hold the bit steady...it tends to walk if held without something to steady the thrust. I marked the tile, lined up the marks through the hole in the jig, pressed the jig tight and inserted the diamond hole saw. It cut perfect aligned drill holes through delicate tile without issue. better than mortar bits I have used, just need to keep initial cut steady. I had to install this vent assembly on new tile. best drill bit I have used for drilling tile, well worth the money.

                    This bit did a great job cutting through the porcelain tile I just installed. I needed to re-install the brackets for a set of folding doors. With a steady hand and low rpms on the drill it is easy to get the hole started. Once you get a bit of the hole bored out you can increase the speed. This drill bit easily drilled through the tile. The only reason I gave this bit a good rating instead of excellent is the porcelain would clog the hollow center of the bit. I had to remove the bit and use a finishing nail that I slightly bent to force out the clogged porcelain core.

                      This mini hole saw was amazing. I needed drain holes in some adorable self watering ceramic pots. An unglazed pot set in a glazed pot for self watering. I ground (not drilled) a hole in inner pot for a wick watering system. My African Violets are very happy now. I had tried a few other methods that were not fun at all. Just the wrong method for grinding through unglazed ceramic.

                      I abused this bit to core out a broken 5/16" Stainless Steel bolt that was galled in a 1/4" SS plate. It took hours and a constant flow of water and three bits but it worked. I used both the Milwaukee and Lenox diamond core bits and they both cut at the same very slow speed. Of course, these bits are intended to be used to drill tile and not SS. The photos show a 5/16" SS bolt being cored out of a SS plate inside of a 3.25" thick door. Drilling through 1/4" of SS with this bit is not a fast process. I estimate that I drilled for 4 hours to remove the bolt.

                        Works GREAT. I burned up three different bits for concrete, tile and assorted other claims, then I bit the bullet (yeah, 13 bucks) and bought the real thing. YES, Granite IS HARD- that's why they use it in grave stones (it LASTS and resists damage) I used a squirt bottle with plenty of water, and with some effort, plunged through 2 inches of solid, HARD surface. Just make sure you have the right measurements first, then check again before you drill. (EXACTLY the right spot- no room for fudging.) Thanks HD, and thanks to Milwaukee Tool once again. The screw and plug are under this shower bracket.

                          Excellent Quality Diamond Bits
                          We used the 3/16” and the 1/4” diamond bits to install a pin mounted logo with standoffs on a porcelian tile wall. The logo required us to drill 107) 3/16” holes and 42) 1/4” holes. It took us several hours to drill the holes with a 18v cordless but these drill bits worked perfect and each hole came out really “clean”. The trick to making these diamond bits last is having a helper spray soapy water while you drill. We only went through 3) 3/16” bits and 1) 1/4” drill bit. The price is good for an excellent product and I would absolutely recommend these bits to anyone, especially those who are tired of using and burning blue pointed tile bits.. :)
