3/4x12 SDS-Plus Rotary Hammer Drill Bit, Carbide Tip 4-Cutter for Brick,Stone & Concrete, Packed of 2pcs.

I used the product to drill through solid brick for the purpose of installing a drain for my dehumidifier.I used one of the two drills, which provided a way to, relatively easily, drill through the solid brick.

As expected

Worked great!

Perfect for my project!

boring landscape blocks.

This hammer drill bit work really well for concrete slabs and if you want holes that remain secure and durable.

I needed these to drill holes in lava rock. They fit nicely into my hammer drill and are the correct size for my needs. No issues so far. They work well even in tough spots. They seem like they will last a long time as there has been little wear and tear even after drilling many holes.

Had to drill some holes on my concrete shed pad for the new shed I'm building to secure the walls to a non-movable surface. This was my ticket to getting the concrete anchors I needed in.I had no problem with my impact drill and these babies going to town. Be sure to use safety equipment, as the dust it throws up can be hazardous to breathe and get in your eyes if you aren't careful.Let the tool do most of the work. Forcing them can cause problems. The hardest part for me was holding the drill steady and straight... so, not very hard at all.I also have an issue with my driveway where it is sinking. I may use these to drill some holes and use foam to "lift" the driveway like I've seen can be done now. I just have to research the correct type of foam to use first.I'm pretty sure these will be used for many projects in the future. Nice and solid, no real wear showing from drilling those concrete holes. Great buy!

Have it a 4 rating just because it came a day late. Bit worked perfectly though. Went through an old brick wall like butter.
