11-pc Masonry Drill Bits Carbide Concrete Drill Bit Set for Stone Tile Brick Ceramic Glass Metal Sheet Plastic and Wood, Quick Change 1/4" Hex Shank, Size 5/32” 3/16" 1/4" 5/16" 3/8" 1/2" with Case

I had to install a new floating vanity and was required to drill through glass mosaic tile and regular ceramic tile. These drill bits were perfect for the job and came at an even better price. Very nice value for the tool set. The sizes are also very accurate as the anchors fit snuggly but perfectly. I highly recommend keeping them cool as you drill. I could hear them getting loud and bogging up as the temperature rose. I used a little spray bottle and kept the cool and lubricated and it made the drilling way for efficient and most likely helped preserve them in the long run. I can't speak if these are high enough quality for professional everyday use but for a home improvement project they are perfect. I would recommend to anyone doing a small to medium size renovation. I have drilled over 30 holes with them for hanging up my vanity, mirror, shower shelves and storage shelves into different types of tile and they were great!

Made installing a new Mose shower seat possible for an 85 year old man. They went through my ceramic tile fairly easily. Tip. Keep a cup of water handy to cool drill and make sure drills are fully charged.

These bits are of modest quality, but at a low enough price that they are a reasonable purchase for those with only a few holes to drill. I generally got about 6 holes per drill when drilling into grout and 1 to maybe 1.5 holes attempting brick. A short job with about a dozen holes used three drills: two dulled and one broke at the tip. At the price, however, this was less expensive than buying one higher quality industrial bit. If I was doing a lot of drilling, I would definitely not buy these. But for a quick job they are OK. Just think of them disposable.

Excellent, sliced through stone easily!

worked perfectly on our ceramic tile. As most everyone is saying, KEEP WET AND COOL. As one of us drilled, the other sprayed water at drilling point plus every 30 seconds or so, we dipped drill bit into water for a about 5 seconds.

These worked great with a hammer drill, fast, only took 2 minutes to drill 4 holes in a hard cement deck. Drilled clean holes for anchor bolts and didn’t overheat, or break, and did not dull at all, very durable at least for my application. It says on the box whether or not to use water on the bit with a normal drill or dry with the hammer drill, which was a good reminder. Has a variety of sizes. I was sceptical of the pointed head design instead of the normal hammer drill bits that traditionally come with cement screws, but was pleased with the ease of use and fast drilling. Would recommend for cement drilling with a hammer drill. I saw some reviews with these chipped after one use, I have to wonder if they didn’t apply water to the bit when using with a normal drill? There are guide pictures on the box. Also worked to drill a clean hole in bathroom tile. I used the drill setting on the hammer drill and periodically dipped the bit in water to prevent overheating. Again, did not dull the tip at all.

I needed some drill bits to get through brick and Hardie Trim. Purchased two different sets of these to make sure I had plenty of bits for the project. I like these because you don't need to have a hammer drill. I also liked these because (per the description) "HEX SHANK FOR QUICK CHANGE: 1/4” Hex Shank fits into all power tools". The only problem is that none of the bits I needed fit into any of the drills that I tried that were equipped for 1/4" Hex Shank bits. That was 3 different Ryobi drills. I also tried a few adapters, and the bits didn't fit any of them. I had to switch to a drill with a regular chuck on it, and the bits got the job done.

Very good on tile and concrete, went in perfect, struggled with normal bits but this so easy

La finura con que perfora

Very good bits good quality

Good

Funcionan muy bien, facilitan el trabajo y su precio no es elevado. Me gustaron mucho.

No las he podido probar mucho, solo una pieza e inmediatamente se rompio la punta, pero aun así no me parecen tan malas...
