Gunpla 10Pcs Multi-Material Drill Bits Set, Cemented Carbide Masonry Drill Bits for Glass, Plastic, Tile, Concrete, Brick, Wall, Wood and Brick Wall 6mm

The price definitely reflects the quality. I used them to drill holes in porcelain tile and it took 3 bits to drill 5 holes. They worked, but the bits were destroyed after each hole drilled. It’s definitely not chance that they sell these in packs of 10. If you have a small job to do, and don’t want to spend a lot, these will get the job done. If your looking for a bit that will last a little while, you’ll need to look elsewhere.Update:I tried taking a spray bottle and staying water on the location of the hole as I was running the bit, and it seemed to help dramatically. I used 1 bit for about a half a dozen holes in glass tile and the bit could have done more.

I use these bits to drill stained glass. It took a little getting used to at first, as is the usual. But I love these bits. If I purchase the assorted sizes from the store - they only have assorted sizes- I don't use all the sizes and also they cost 10.00 for 4 bits. These are really fantastic. Great price, great product.I ordered 4 pkgs of 10 a year and a half ago. I drill glass every single day. Hundreds upon hundreds of holes and I am just now down to my last couple of bits.

These are phenomenal! I was spending thousands a year on drill bits because we were going through so many. They aren’t exact 1/4” but they tolerate anchors just fine. I drill through any type of tile no problem, but lately the new trend is nano glass and hard porcelain. Both of which require 1-2 drill bits for every 3 holes drilled. Some installs required 30-40 holes. When I got ahold of these I was very happy with what I saw. One bit lasts 6-7 holes. Just make sure you’re keeping it cool by squirting it with a spray bottle. I see a lot of “contractors” here complaining they got chewed up. Go figure. There’s no such thing as an invincible drill bit! Overall very pleased and the holes are clean, haven’t cracked a tile yet with these. They also punch through metal studs with ease. Check out some of the recent work installed using these bits

These 1/4 inch glass bits measure up to Bosch for drilling ceramic/porcelain tile, for (much) less than half the price. Gently rotate your drill as you work, and it will speed up the cutting immensely as well as help avoiding snapping off the cutting "wings". Quench it every 20 seconds of drilling.

Crap product. The first one broke as I set it on the counter. The rest all shatter in seconds of using. Horrible

I purchased these after reading the reviews and was a little skeptical, due to the price. However I was amazed at how well they worked. I had some porcelain tile I needed to drill holes through to anchor a fire pit. Based on one of the reviews, I took a water bottle filled it and drilled a small hole in the top. As I was drilling the tile, I squirted the drill pit with water and much to my surprise the drill bit cut right through the tile. I drilled 4 holes with a battery drill in less than ten minutes. These bits are great. I tried several other bits and they would hardly scratch the surface of the tile before the tips were gone. Great buy at a great price.

These were amazing! Drilled straight ceramic, porcelain and stone tile with no problems at all. Made the job in hand so much easier and hands down beats the more expensive bits that burn up after 1 use! The price is great and the quality is superior. Will definitely be ordering more when these need replacing!

These looked like they would work, and they did on soft concrete with no aggregate in it.However, if the concrete does have aggregate tip breaks off immediately when it comes in contact. I needed to drill hole in concrete slab to mount thresholds and these didn't serve the purpose.

Using my old masonry bits, I was having difficulty drilling into my ceramic tiles to hang a shower curtain rod. These new bits did the trick. Worked really well, but only got 3 holes out of 1 bit before it became too dull to use. I guess that's why they come in a pack of 12! Would rate 5 stars otherwise. Worth the 13 bucks for sure.

Very bad quality two bits Brooke before I can finish half of the first hole.I had been waiting since yesterday to receive them, the other bad part was to take out the broken pieces from the tile without damaging the tile

first use one bit broke on ceramic tile , I install tiles all the time and and ceramic is soft. I am afraid to use on porcelain tile.

This product was surprisingly very good... if you know how to use it and it’s used properly... I highly recommend.... I do custom shower glass and I have not burnt through the bits... yes... but them... you won’t be disappointed

Very good but expected different sizes.
