So though these tools are made in China they seem to be pretty well made. I did have to provide a pair of O-rings. But that said it allows you to use your SDS MAX hammer drill with diamond core drills. Dry or with the water swivel you should be able to get things done. All in it is far cheaper than a dedicated core drill motor with water, like 5 to 1 cheaper. So highly recommended.
