Review on Oshlun SBF 054030 8 Inch Bushings Ferrous by William Bell

Thought I'd try this on my soffit replacement project. Bought all new material 12 feet long and 16 inches wide with center venting. Industry standard material available at any large cardboard or siding store. I decided to find an alum blade for my battery powered circular saw and give it a try. everything is fine on the solid part of the panel, but the ventilated part of the panel tears and tears, which is not good for either the optics or the installation time. Then I took out the old plywood blade by turning it (as before ) and it works fine Tears the material not and half the price of this blade.
