Well made. Virtually no instructions with the tool, so if you need a manual, refer to the Amazon writeup. Using this core drill with an angle grinder requires some skill, practice, a steady hand and some strength to get the hole exactly where you want it. For professionals who will use it every day, shouldn't be a problem, and this is a solid tool. For homeowners or DIYers, the included drill adapter makes it usable with a ¼" drill; however, you will still need the aforementioned skills, strength and steadiness to use it successfully. So if this will be your first time drill a hole in stone, tile, granite, etc. I suggest you might be more successful with a hole saw that has a pilot tip, which makes precisely centering the hold easier and is then self guiding for cutting the final hole. Also, it comes in a nice, sturdy plastic case that will protect the hole saw between uses.
