I'm tiling my bathroom and need a 5 1/2" hole for the shower valve. It hurts me that I had to spend $50 for a one-time use, but it's work That had to be done and it was the cheapest available. But it worked great. Nice clean hole. The beat feels very solid. A tip: wear headphones! Cut through the tiles on the floor with that sound! How loud? Spinal Tap was rehearsing next door and they asked us to turn it down.I speak loud.One nice thing that isn't in the photo is that the spindle has three sides that are beveled to hold it securely in the chuck.
