Review on 🔪 Bi-Metal Fiberboard with Enhanced Positive Cutting Ability by Roberto Evans

I have used this type of crown for many years with mixed success. This one did a great job on a project I was working on. I had to cut 2 holes but the chest freezer is insulated so I had to cut 4 pieces of metal and this saw went through the metal on the outside, then through the insulation and on the other metal side with ease. Also, copper pipes were hidden in the insulation of both holes. This saw cut through everything and the teeth were as sharp as new when the job was done. (I'm making a fish smoker.
