These drill bits worked as advertised in drilling concrete. As long as you use a hammer drill you will have no issues in making holes into masonry. It comes in useful sizes and makes clean accurate holes. None of the bits broke on me when I used it.

I bought these to help hang items on our dealership service department shop walls. They are great for drilling pilot holes to insert anchor bolts.

This concrete drill bit set is designed for tackling tough materials like cement, brick, tile, and plastic. The industrial carbide tips hold up well under pressure, maintaining sharpness even after multiple uses. The hex shank design ensures a secure grip in the drill, preventing slipping during operation.With eight different sizes, this set covers a range of applications, from light-duty wall anchors to more intensive masonry work. If you frequently work with hard surfaces, this is a reliable and well-constructed drill bit set that performs as expected.

Like Buying Chinese Cheap Bits from TEMU, these Bits were very affordable but, the Big Difference is these Bits are of High Quality and Lasted through Multiple Usages. These Bits actually saved me on a recent project because of their Durability.

I really like these hacks attached and bases for these drill bits. The excellent quality of the carrying case is another positive as well. I like the fact that I can use these in my handheld screwdriver my drill or even in my impact wrench.The hex shape of the base allows it to be used in several flexible attachments so that it can get into the tight corners as well.It is a great value for the money. However, the drillbit lasted for less than expected sharpness and needed to be sharpened after about 25 uses.Which is expected for this level of drill attachment as it is not a tungsten or carbide tip, it is a standard steel tip made for drilling into soft material such as PVC or wood.

I ordered this GRENPRO 8 PCS Masonry Drill Bit Set for some DIY projects around the house, and it has been a solid addition to my tool collection. This set includes a variety of sizes (from 5/32" to 3/8") which is perfect for drilling into different materials like concrete, brick, and tile. The bits are made of YG8X alloy carbide, which seems to make them both durable and effective, and I’ve had no trouble using them on cement or brick walls.One of the features that I really appreciate about this set is the shockproof design. The drill bits stay stable and maintain their performance during use, which ensures consistent results. Even when using them with my standard drill (not a hammer drill), the bits still cut through concrete easily. The U-shaped slotted holes help with dust removal and heat reduction, which I think is a great design choice. It made the drilling process smoother and faster, with less mess to clean up afterward. The sharp side blades also seem to improve the drilling speed, making these bits work quicker than the older ones I had.The set is compatible with a wide range of tools, including electric drills, power drills, and hand drills, which makes it versatile for many tasks. I’ve used them for both small and larger holes, and so far, they’ve performed well. I do wish the storage case was a bit more user-friendly, as it's a thin plastic molding that requires cutting to open, but this hasn't been a huge issue for me. I simply modified it to make accessing the bits easier. The bits themselves are high-quality, and I can already tell they’ll hold up well over time, although only time will tell how long they last compared to other brands.Overall, I’m really happy with this set. If you’re looking for a reliable and affordable set of masonry drill bits, this one checks all the boxes. The performance has been great for the work I’ve done so far, and it’s a solid set that I’d recommend to anyone doing similar projects.
