2 inch Diamond Hole Saw Bit for Glass, Porcelain, Quartz, Granite, Ceramic Drill Bit Tile Hole Saw Diamond Drill Bit with 3/8 inch Standard Shank for Drills

So experience and my gut said to try this out due to the mostly positive reviews. For 17 bucks as opposed to $45+ from retail/hardware stores I figured it was worth the shot, especially since I only needed to make one hole. My mission was to drill a 2-1/2" hole in 3/8" porcelain tile for a shower diverter. No offense intended, but I've learned that some people base their reviews on their own inexperience, lack of skill or failure to follow directions. That does not result in an accurate product review - the product’s quality and performance is supposed to be reviewed and not be based on someone's inadequacies. Before purchasing an item, I run through many reviews to get a feel for the product. I've learned to disregard some reviews based on how they are written and by getting a feel of individual skill levels - whether it's for a tool or a blender. My method once again paid-off.Some denounced the hole saw because it didn't have a pilot bit, but a pilot bit would "walk" on tile and glass anyway and wouldn't serve much of a purpose. I created a guide out of a leftover piece of foam backer board and clamped it to the tile. It served as a drill guide and also helped keep a "dam" of water around the hole. I then had a hose nearby set on "mist" to supplement the water and clean-out the debris. I set this up over a 5 gallon bucket and began drilling. I used a variable-speed drill and squeezed the trigger just enough to give a pretty low RPM and applied fairly light pressure on the tile. Because I was using a guide, I didn't begin on an angle as you typically do with a diamond bit. After about 20 rotations, I felt a groove being made. At this point I knew it was working and continued drilling, cleaning out the hole with water spray every minute or two (the guide kept a pool of water in-between spray intervals). Within about 5 minutes the saw popped through. It probably would've been quicker but I stopped to examine the bit to see if other's claims of the diamond dust wearing smooth came true - but it didn't. I was surprised at how clean the hole was and that it only varied in size by 1/8" (in this type of work, that is considered acceptable - we're not assembling the space shuttle engine). So...I can almost guarantee failures were the result of not enough water, spinning the bit way too fast as if it was a high-speed bit, or leaning into it with too much pressure. I only needed it for a single hole but don't see why it wouldn't get through a few more. Now that being said, it seems as if it's designed and constructed for occasional use and is not meant to be a daily-use hole saw for a granite or tile contractor. The hole saw is ready to use as purchased - its arbor is welded to the bit and will fit in any standard 3-jaw drill chuck. It served my purpose well and I would recommend it for a few light-duty applications.NOTE: I purchased this item on Amazon for full price and have no affiliation to the seller. I try to write helpful, unbiased and insightful reviews because I also read reviews prior to making my own buying decisions. I notice many reviews lack helpful information, are not well written or give poor reviews based on not reading directions or failing to read the product details prior to purchasing. Writing valuable reviews helps pay it forward.

Got this to cut several holes through some tough large-format tile. The hole saws LOOK flimsy, but they do a great job! We were using a battery drill, low speed, with a mister-spray bottle (recycled glass cleaner bottle) to keep the tile wet.The saw is hard to get started, even starting at an angle. But we drilled a hole in some scrap tile, then used that tile as a positioning jig to keep the saw steady when starting out. Once we got a few millimeters into the tile, we could remove the jig. (And the water just runs down the side of the hole saw, so the jig doesn't cause any real problems.) For what it's worth, the hole-in-a-scrap jig is also a great way to cut holes near the edge of the tile, too!There was definitely punch-out, so make sure you start your holes from the finished surface of the tile.We had to install 4 valves using these holes, as well as a much larger mixing valve with an irregular opening. We used this same saw to make the corners of the irregular opening, so I would say we did 7 holes worth of cutting with this saw. It still works fine, and doesn't seem to have lost much if any of the grit. So I think it's pretty durable.(Edit to add:) It's worth pointing out that we tried some alternatives first. Specifically, we first tried a tile-cutting bit in a spiral cutter (rotary tool). That might work for thinner, weaker tiles, but for thick, large-format porcelain tiles it didn't do the job at all. We couldn't get a single hole cut before burning up the bit. So long, $6. The next thing we tried was the diamond tip glass and tile drill bits: if they would go through fast, we figured we could "perforate" the tile with a bunch of holes in a circle, then punch out between the dots. No such luck! Those bits wanted nothing to do with this tile. So MAN! were we glad this hold saw worked!

For a home owner who only need a few holes drilled, this is perfect. It cut through the stucco and plaster with ease. I can't speak of durability since I only drilled two holes with it, but it seem to hold up fine. The grit of diamond are not too coarse, so it should work fine for tiles and marble.

I needed this only for cutting a hole for shower pan waste pipe. It shot through the cementatious thinset and leveling compound and right into the wood and through a nail. I used a little water to lubricate the cut and reduce dust. There seems to be plenty of material left so I'll get a few more similar cuts.

I needed to make a hole in a tile to fit an umbrella for my patio set. I went to the store where I usually go to buy tools and found one, but the quality was not so good, and the price was expensive. I checked in Amazon and found the Drilax hole saw; it was half the price compared with what I saw in the store and the reviews were very good. I ordered it and got it the next day. I immediately made a hole in the replacement tile for my patio set. The saw worked perfectly; it made a perfect hole of the diameter I required. I was so happy with the results that I made two extra tiles for the umbrella in case it breaks again. Great price, quick delivery and very good results. I used a press drill and lots of water to keep the tile and tool wet. If you want to make a hole in a tile, this is the tool you need to order.

My daughter wanted to cut a drain hole in a ceramic bowl so that she could use the bowl as a bathroom sink. In our case, a 1_5/8" hole was required and so I purchased this hole cutter. Placing the bowl with concave side up, I added about 1/4" of water and set my drill press to the lowest speed. I was able to drill a perfect, smooth hole in about a minute by applying just a moderate pressure to the cutter. When finished, I could see absolutely no wear to the cutter. In my case, I was extremely satisfied.
