Protected segment turbo blades are an installer’s best friend. They not only cut extremely well using the same technology as our best turbo blades, but they also have some extra benefits. Diamonds on the face of the blade can be used for light sanding and grinding. Use of these blades means less time changing out tools and fewer tools to carry. Flush mount holes are on the 4.5 inch, 5 inch and 6 inch sizes.
