Spyder Products has been around for less than 10 years and has already come up with several industry-changing tools. And its new hole saws are packed with a ton of features. The Rapid Core Eject system makes removing the core as easy as pushing a button and pulling down on the saw blade. The carbide-tipped blade shown here rips through wood as if it were cardboard and can even drill through concrete!
You can also enlarge existing holes. For example, if you need to enlarge a 2-in. hole into a 3-in. hole, just install a 2-in. hole saw inside a 3-in. hole saw. The 2-in. saw acts like a guide instead of the drill bit … that’s impressive!
