Concrete/Masonry Drill Bit Set 5-Pack (1/4" 5/16" 1/2") Industrial-Strength Masonry/Cement Drill Bits, Tri-Shank Heavy-Duty Carbide Tip for Concrete, Brick, Tile & Glass

These concrete drill bits are seriously heavy-duty. They cut through brick and concrete like butter, and I haven't had any issues with them dulling or breaking even after multiple uses. The carbide tips stay sharp and make drilling much faster and easier than with regular bits. The 5-pack gives you a good range of sizes for different projects, and they're all clearly marked so you can easily find the one you need. If you're planning on doing any drilling into masonry, these bits are a must-have.

At such a low price at time of review ($2.99), I wouldn't expect much out of these as far as longevity or durability. But most of us don't need masonry bits on a regular basis, so I figured trying these our would be worth it for one home DIY project.I got these to complete a camera doorbell project. But it turns out that I'll be mounting it to an aluminum covering, so I may not need them. I may need to drill under/past the aluminum to a harder surface, in which case I'll be able to give these a more thorough review.In the meantime, here are the tips from the back of the product. I have never drilled through brick, so I found them to be informative, and they contradict some of what other reviewers are saying. I didn't fully understand the second tip, as you wouldn't be able to get a screw to curve through a whole. Maybe it's referring to the very initial contact with the material.WARM REMINDER1.When drilling hard materials like ceramic tiles marble, glass, granite, add water to cool.2.When starting to drill, apply force from light to heavy, and the drilling angle should be from inclined to perpendicular.3.When drilling large diameter holes, start with a smaller drill bit and gradually increase size.4.NOT for toughened glass. Not applicable to electric hammer drill.

I've done a lot of drilling into hard material, and the package describes what these drill bits can handle. However, I have never had luck drilling into glass, and I don't even want to prove that the bits can drill into glass without shattering. Other than that, it's a great set of tough drill bits.

These masonry bits are a good choice for drilling into concrete or limestone.

Every time I need to drill a hole through brick or concrete, I have to scrounge around to find the right masonry bit. I grabbed so I'll have peace of mind the next time the need arises. They seem pretty solid for under a buck a piece. Will update this review once I have put one to the test.

I am a DIY guy and got these Professional Concrete Drill Bit 5-Pack Masonry Drill Bit Set knowing what to expect from a set at that price point. They are listed as professional grade but after using a bit to drill several holes in bricks, it lost the power and needed to used another one since it was taking long and long drill each hole. I am just an aficionado so not mind buying this type of product, but I would not recommend if you need these bits for a business.

I need a concrete bit for a project in the basement. I priced out bits via hardware stores. I found this set for the same price as the one bit I need for my project. No brainer got the set and very happy with the bits.

Needed drill bits to get through the brick wall above my front door, to install a security camera, and these got the job done. I don't know much about drill bits as far as quality or price goes, but I really can't argue with the price of this, and like I said, it did what I needed. Would buy again if needed.
