A bit that properly drills through glass backsplash mosaic. *by K***K on Reviewed in the United States on February 19, 2024* My wife and I have taken on a project to add a backsplash in our kitchen. Which included placing tile behind the range and range hood. I had a wet saw for the all the straight cuts (which I can't recommend enough if you're doing this sort of DIY project). But there was still a need for some alternative cutting methods. As I needed to locate a hand-full of holes and odd shapes.I tried all sorts of things with no success, to include the following...- Goldblatt Glass and Tile Nippers: These were terrible. Super inconsistent cuts. One cut would have a fairly clean edge. The next would be ragged. Tile. Glass. Didn't matter. It was all terribly inconsistent.- Glass Scoring Tool: This was even worse than the nippers. Barely made a scratch in the glass. This sort of thing might work for very thin glass. But if you're wanting to use it for backsplash mosaic, take a hard pass.- Bosch Glass and Tile Carbide Drill Bits: Normally Bosch makes pretty good stuff. But these aren't one of those things. They kind of cut into the glass backsplash material. But made very little progress. And eventually would just crack the glass. I tried these in conjunction with water, and glass cutting oil. Neither of those things helped. Maybe they'd work in tile. But something super hard like glass is just too much to ask of these bits.I was just about to give up, but I really needed a way to drill a handful of holes in the glass tile so that I could bolt the range hood and chimney to the wall. So I took one last shot and bought these diamond coated drill bits. The blade on my wet saw was diamond coated, so I was cautiously optimistic that these would do the job. And man did they deliver!Some of the reviews mentioned that these bits didn't last very long. Maybe a cut or two. Fortunately, all the holes I needed were the same size. So I bought the 5-pack of of 3/8" bits. Hoping that I could eke out the cuts before they all went dull.When I received the package, the bits appeared to be of decent quality. The coating looked and felt fairly thick. Although the amount of coating varied quite a bit between the 5 bits. Not knowing how well they'd work. I grabbed one of the more lightly coated bits, chucked it up in my drill press, and tried a test hole. I figured I should go through the learning curve with one of the lesser coated bits; saving the more "healthy" coated bits for the actual holes.To my surprise, the first bit cut through wonderfully! Thinking it might be a fluke, I did another test hole. Then another, and another, and another. This thing just kept on chewing through with no issue. Feeling confident in my setup, technique, and the bit, I moved on to the actual holes. In the end, that one bit knocked all of them out with a perfectly consistent cut. About 15 holes in total. It even managed to drill a hole right on the edge of one piece of glass tile. Which is a tough hole to make even in something like wood. Let alone glass.All that money (around $75) spent on the other tools that did a terrible job, to end up getting it done with just a single bit from a $7 set. In the one picture, you can see the variance in how well each of the bits from my set was coated. For reference, the one with the arrow on the left is the one I used for all 15 cuts/holes. As you can see, it basically looks as new as the other 4 unused bits. And while the coating wasn't as thick as some other bits in the set. It didn't appear to lose any of the coating throughout the process of drilling all the holes. How it looks is exactly how it looked when it was new in the package.Bottom line, this set is awesome! And is a crazy value at only $7. Now, there are still a number of reviews from people who had a wildly different experience. Complaining of poor cuts and non-existent durability. What I can say about this is that it's likely due to improper use and setup. So, I'll close with some advice on how to get the most out of these bits.The key to cutting glass comes down to speed, pressure, and cooling/lubrication. Running these bits fast, hard, and dry is a recipe for a bad experience. They might do the job, but will wear out very quickly. So if at all possible, find a way to use them in conjunction with water or glass cutting fluid.What I ended up doing was to place the tiles inside a shallow Tupperware lid. I then filled the lid with cold water, to the point where the tile being drilled was completely below the water line. I simply then clamped the tile inside the lid to my drill press table. Which was the perfect makeshift water cutting setup.The next key is "speeds and feeds". You'll hear this term a lot in the machining world. And the same attention is needed with glass. I set my drill press to 650 RPMs, and likely could have gone slower. When drilling, I used very light pressure. And fed the bit very slowly through the material. Taking breaks every so often by raising the bit out of the cut, and then back in (i.e. "pecking"). This keeps the glass and bit from getting too hot. And also works to eject the glass fragments from the hole.The point here is, go slow! Once you feel like you're going slow enough, slow down even more, lol. Especially at the end of the cut/hole. When you get to that last little bit of material, take your time. As this will mitigate pretty much any "tear out". Just apply enough force for the tool to do the work. I'm sure you could make the same cuts with a cordless drill. But a drill press is a far better tool for the job. As it really allows you to be precise with the angle of the bit, drill speed, and feed rate.The only other thing I'll call out is that even with perfect technique and setup, you'll likely get some tear out. However, these bits leave a very clean hole at the "top" of the workpiece. So I found it was best to start drilling through the face that'll be visible in your final project.If you're using it for a glass backsplash like me, odds are that you'll end up with some paper backing that is a little torn around the underside of the hole. Nothing major. But it is noticeable. My solution was to break into my wife's nail polish supply. I mixed a couple together to get the right shade of gray. Then simply applied the nail polish on the back of the tile, in any spot where the colored paper backing had been removed. Once it dried, it blended in perfectly. So well that my wife couldn't tell where the colored paper backing ended, and the nail polish pigment began.TL;DR - These diamond coated bits are outstanding! Just use them the proper way, and you'll get a lot of life out of them. Which is wet, slow, and with light pressure. I can't recommend these bits enough! Skip all the other style glass bits. These are the perfect tool for the job! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Excellent *by J***R on Reviewed in the United States on July 14, 2024* I have only used the biggest one so far, but the quality for the price is awesome. So far I only made a couple of holes and it worked really well, no effort on porcelain tile which has been always my least favorite.Only thing I would add is a way to center the piece so damaging the tile could be avoided for sure.Anyway 9,99999 out of 10. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Bits work well but Jig is not the greatest *by D***S on Reviewed in the United States on September 14, 2023* The bits seem to cut well and the size assortment is good. Jig works so-so. Bearings keep getting loose and coming off. But good overall value for the money. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/188820064-diamond-drill-bit-10-pcs-glass-diamond-hole-saw-set](https://www.desertcart.co.th/products/188820064-diamond-drill-bit-10-pcs-glass-diamond-hole-saw-set) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
