Masonry Concrete Drill Bit Set for Tile, Brick, Glass, Plastic and Wood, Tungsten Carbide Tip Work with Ceramic Tile, Wall Mirror, Paver on Concrete or Brick Wall, 10 Pcs

I used this set to drill holes in ceramic tile to install tub handrails. It did an awesome job with just a few drops of water for lubrication and cooling. I was able to drill 16 holes with the same drill bit. It stayed sharp and was durable.

I purchased these to mount several bath and shower grab bars for my elderly mother-in-law. I’m actually very impressed with the performance of the bits! They work exceptionally well! There is no bit wandering on ceramic tile and they produce clean, smooth, chip-free holes. These are very fast drilling and due to their design, produce very little friction generated heat and virtually zero vibration while drilling. I highly recommend these bits, especially considering their price point! 😀

I was doing several projects that required drilling concrete for anchors, so I bought these. the price was reasonable, and they come in a nice case. I use them in a small hand drill with a hammer function. I try to keep them wet to cool the bit. Still a tough life. I had one break off in the hole, and I had to drill an alternate hole for the anchor. I get about 4-6 holes per bit. Someday I'll get an SDS drill, but I find it hard to justify that expense for the small amount of concrete drilling that I do.

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.

Excellent product

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.

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.

Drilled through brick without hesitation! Excellent material for drilling.

La finura con que perfora

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...
