6PCS Rock Splitting Wedges and 1PCS Rotary Hammer Drill Bit, Wedge and Feather Shims, Stone Splitter Tools for Granites, Concretes, Boulders, Volcanic Rocks, Limestone Rocks

Just starting breaking up a concrete base for a basket ball hoop. It seems to be working great in breaking the base up in manageable chunks. Bit seems to holding up and the wedges work great. The hammer drill is a little jarring, but it sure beats using a 10lb sledge.

I read some reviews that these were not up to the task. They fully exceeded all my expectations. Here is how I was successful using these to break up concrete. First, be sure you drill your holes far deeper than these wedges. Use the proper diameter drill bit. For the concrete ranging from 4 inches to 6 inches thick, I did holes 4 to 5 inches apart. Assemble the three metal pieces with the heavy rubber washer. Barely engage the actual wedge. This lets you drop the assembly almost completely into the hole. I also tapped both outer sleeves down as far as they would go, just tapping them. Then, using a single-jack, start tapping in each of the wedges. You will hear it and you will feel it as they bottom out. Just keep working back-and-forth from one to the next. You will quickly see a crack forming from hole to hole. When you drive the wedges down, don’t keep bashing them. If you have reached the rubber washer, it is time to stop. It is critical that you have a gap on the away side of the piece you are breaking off. There must be some place for the waste to move into as you are driving in those wedges. I still had to pry the slabs away. In fact, I used my single-jack to break the slabs apart once they broke off. It made it easier to work them out of their nest. I did use a drop of three-in-one oil on each of the three parts. Just seems to help them not get bound. Like any tool, you must treat them as they are designed to be used, and you must not abuse them. If you try to take shortcuts and use the wrong sized hole, for example, you will definitely have problems. If you try to brute force your way into success, guaranteed you will have problems. If you bash the ever-loving snot out of these, guaranteed you will have problems. Treat them right, and you will have success.

Drill bit is terrible. It was dull and unable to drill into rock after the first few holes. Quality one I have are 30-40$ alone with out the feather and wedges. The wedges work great and are worth it alone for the price.

Does the job ! Splitting the rock was easier than expected with this tool. If you don't want to spend a lot of money, this is for you.

Worked perfectly for what I needed. Digging a hole for an elevator and have to do it by hand because in an old building. There was a rock too big to lift and we drilled several holes to try to break it without success. Put just three of these in when they got here and in one minute the rock was cracked in half. The drill bit works and for the cost it’s ok. I used the other bits we had so could go little deeper and faster but it does work. Very easy to use and just in the time it saved me they paid for themselves. In the photo you can see where we drilled before to try to get the rock to break. I put 3 in spaced out and you can see how much they had do themselves

The wedges work great. The drill bit that came with the set did not work for me. I bought a 9/16 in. bit that worked better. 9/16 in. is slightly larger than the tip of the wedges so the wedges slide in more easily.

Drill bit is worthless-I used a hammer drill and cooled with water. I drilled and drilled and only got down 1/2”, put in a used bit I had and drilled down 3” in seconds! Wedges worked fine

I just opened the box and clearly the bit is SO poorly made. It's blackened tip has two big divots of metal missing and it's significantly wider on one side. I don't see and visible problems with the wedges so if you've found rocks you don't need to drill...

Initially the package came without the drill. Once I got in touch with the company they sent the drill. It arrived today and I am satisfied.

When I bought these things, I wasn't sure if this could really work. I have destroyed very large concrete rings with them. It really works and it works amazingly easy. If you search for a possibility to destroy large concrete parts - Buy it!

100% satisfied

can be split because of rubber

Ist für den Hobby- oder Hausgebrauch sehr gut und genügend. Achtung auf die Gummis, würde dem Hersteller empfehlen für einen kleinen Aufpreis ein oder zwei Gummis in Reserve mit einzupacken.
