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

Bits work very well. I had to drill a 1/2 inch hole in a plastic planter this bit worked great.

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.

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.

Tried to drill into dense brick with different types of bits, I bought these and it was effortless! 100% buy! People do talk about bits breaking related to their heat tolerance, but I did four holes each about 2 inches with a brief pause between two and it was flawless.Great quality. No problem with brick.

Talk about impressed.. i dont do much hard drilling through super thick stuff but the convenience of just being able to pick up 1 bit and get to work is enough for me. From wood, steel or concrete. So far these things are a beast to have .

Very usefull

Bits dulled rapidly. Can’t be sharpened. Drilled only 6 total drain holes in 2 clay pots and 3 bits in the trash after.

Works very well for concrete 3/8 sleeve bolt for anchoring gazebo. Very precise and clean drill, less effort. Without the need for impact/hammer drills which this doesn’t support, which was fine. Wished I had used this before drilling the 8 holes, only used for the last 2.5 holes.
