Review on Bosch HB475-4-3 Bi-Metal Hole Saw by Michael Zambrano

I ordered this because it could be delivered to me in two days and I needed it quickly. It worked great on plywood, but I don't think it would be any harder on steel or anything harder. I usually buy Milwaukee hole saws and these are the best hole saws I've ever used. This hole saw from Bosch cannot be compared, but it will help you in every situation. The design of the tooth tells me it's only made for softer material. In addition, this hole saw likes to slip off the hole saw chuck. I don't have that problem with Milwaukee.
