Cuts the holes OK, and is well made. But the gasket ring is too shallow and not very flexible. So it does not make a good seal to keep the dust in, especially on textured ceilings. The spring is also a bit weak. When you push hard enough to try and get a good seal, the blades hit the surface before the seal is formed, and the drill bogs down. I ended up wrapping foam pipe insulation around the circumference of the disc to help make the seal and keep the blades away from the surface until they spin up to speed.

I was actually surprised. This hole saw cut real well, even into wood paneling that was being used as the ceiling cover

This is a great product! Perfect for recessed light holes with no mess to clean up. Have installed 10, 6 inch lights so far and works perfect!
