Excelente por el precio

If you own a hammer drill, you’re going to want to own this set. It contains just about every tool you’re going to need to get the most use out of your drill. The set comes in a nice fitted case, and there’s a good selection of chisels, both broad-faced and pointed. The finish of the tools is excellent, and the construction appears robust. One thing to note, however, is that the drill bits are marked in millimeters, not inches as shown in the listing, and one was missing its mark altogether. In fairness, it’s really not a big deal, as drilling into concrete is not a precision operation. I simply matched the bit to the hardware I was wanting to set. Overall, considering the tremendous value found in this set, I think it’s a point I can overlook.

While working on a 3-inch thick layer of concrete, the base of the tool broke with very little effort when using the rotary hammer.

These work great Good value. I had a big concrete job My the chisels and drills still look like new. Price was just a bit more than 1 chidlr from harbor freight.

Great production quality And great price 5 stars to the seller

These are good masonry bits. They drill precise holes, perfect for running pipe or conduit through walls. I would buy this product again.

The first bit(wide chisel) broke within minutes. It looks new but it's broken. The one drill I used seemed to be fine.
