What's special about these hole cutters?

Greenlee's hole saws allow you to cut through steel, tin, aluminum, fiberglass, wood and plastic. The strong M42 alloy blades provide you with long lasting use and eliminate the need to constantly replace blades. The unique steam oxide finish won't gum up or slow cutting as there is no paint used in this process. Each saw has an extra-thick back plate to minimize vibration for smoother, easier cutting and runs cooler for the best performance during each use.
