This Hole Saw is great for plaster work. It also works well with drywall. The special cutting surface of this hole saw prevents it from wearing out more quickly when working with plaster than a commercially available lightweight built-in hole saw. I've gone through 3-4 regular tooth holes over the years as they don't last very long every time they're used on drywall. This hole saw will last a lot longer if used on plaster and should last a very long time if used primarily on drywall.
