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 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! 😀

Great tools . Fast and reliable

Great quality bits for the price.

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.

They work like a charm, wasted a lot of money, buying all the brands and types. You can’t beat these for the money.

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.

Not great. I only managed to get about 2-3 holes drilled with each size before the tips broke off. The bits dulled very quickly when drilling ceramic tile. I eventually got through but these turned out to be a one-time use to make 6 holes, and now need to be thrown away.

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.

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...
