TITGGI 1/4" (10PCS) Masonry Drill Bit Set & Cement Drill Bits, Professional Concrete Drill Bit Set for Glass/Brick/Plastic/Cement/Wood/Tile/Etc, Industrial Strength Carbide Drill Bit Tip

The bits work best if you use water or oil to cool the bit while cutting. Note: the words "for... tile" is in the website description; tile is not included in the provided instructions. When the bit becomes over heated, it cuts nothing and the life of the bit drops significantly. I normally drill for 8 to 10 seconds (smoke/steam is visible) and cool (dunk) the bit in water for 2 to 3 seconds. I use a rubber grommet (like a faucet washer) to minimize the impact of the drill on the tile when breaking through/completing the hole (the amount of pressure applied as I drill is high enough that the drill chuck will hit the surface of the tile before I can react, i.e. pull the bit back). The rubber piece has a hole that fits over the shaft end (not the cutting end) of 1/4 inch bit.

I bought these to do a couple of projects on a brick house. Admittedly the brick on this house is a hard as any I have ever seen. The house is more than 50 years old. Using the smaller 1/8 to drill two pilot holes for a hose rack I went through the first bit in one hole of about two inches depth. It just wore out. I use the next size up for the second one. From the looks of it, it will not drill more than three. The larger bits work fine if you control speed and heat. Just don’t expect the to last long enough to go into the tool drawer.

This set worked great drilling through ceramic clay pot. It takes a while to do but it be patient.Strong, sharp and good vale for the price. Like the fact that they come in a small strong case.

Great set of bits, as with all tools tbere is care needed to keep them working at top performance. Lubricating with water while drilling is important. I was able to drill 6 holes carefully and precisely starting with tbe smallest bit and kept stepping up. No damage to the tile and drilled the holes in no time. Will buy again if these ever go dull from the abuse we can put on tools. Cheap enough to buy a d have in the tool box but sturdy and strong enough to rely on them for big jobs.

I recently purchased the masonry drill bit set with high hopes, given the positive reviews and reasonable price point. While my overall experience has been somewhat satisfactory, there are a few notable areas that fall short of expectations.Firstly, the packaging was robust and secure, ensuring that the drill bits arrived in pristine condition. The bits themselves appeared well-crafted, with a solid build that inspired confidence. The range of sizes included in the set is commendable, providing ample versatility for various drilling tasks.In practical use, however, the performance of these drill bits has been a mixed bag. On the positive side, the bits managed to penetrate standard brick and concrete surfaces with relative ease. For light-duty tasks, they performed adequately, maintaining a sharp edge over multiple uses.Unfortunately, when tackling more demanding materials such as reinforced concrete, the limitations of these bits became apparent. Despite following best practices for masonry drilling – including using a hammer drill and applying steady pressure – the bits showed signs of wear more quickly than anticipated. The cutting edges dulled after just a few intensive drilling sessions, leading to decreased efficiency and increased effort on my part.Another point of concern is the heat dissipation. During prolonged use, the bits tended to overheat, which likely contributed to their premature wear. Frequent pauses were necessary to allow the bits to cool down, disrupting the workflow and adding to the overall time required to complete projects.

Other drill bits from the hardware store did not get the job done. These drill bits worked just great!

Had to use two to drill through some stone above my fireplace. Definitely need water to lube it up.Not built for longevity but gets the job done.
