Oshlun Sbf-072540 7-1/4-Inch 40 Tooth Tcg Saw Blade With 20Mm Arbor (5/8-Inch Product Description Our ferrous metal blades have been designed with a durable carbide grade and triple chip tooth grind which ensures an extended cutting life of all types of ferrous metals (mild steel) such as steel studs, angle iron, pipe, rebar, channel, flat stock and more. They can also be used for cutting non ferrous metals such as aluminum, copper and brass. The specially formulated C-6 micro grain carbide with titanium lasts longer and leaves a burr free cut with little to no sparks or dust, which are common when using abrasives. They can cut 5 to 10 times faster and last up to 30 times longer than abrasives, allowing fewer blade changes and increased production. The higher tooth count blades are better suited for thinner materials, while the lower tooth count blades are better for thicker materials. WARNING: Not recommended for cutting hardened materials. Never use on saws that run above the rated Maximum RPM. Proper clamping devices should be employed. All trademarks and tradenames are property of their respective owners.
