I was in no hurry to buy this drill as it is made in China, but I was pleasantly surprised by its quality and performance. I didn't have an SDS bit, so I just cut off that portion of the shank with a cutting wheel and installed it in a 1/2" cordless drill chuck. Drilled a 3.5" diameter hole through a brick wall. The hole saw isn't deep enough to cut straight through without hitting bottom first, but if you go as deep as you can it was very easy to chip off/break out the plug and then cut out the rest of the hole.At the carbide tip of the center drill and the carbide teeth of the hole saw no wear was evident.The cut was smooth and not jittery,I did it dry (no water) and it worked fine.I would buy again.
