The Freud Non-Ferrous Metal Blade produces a smooth, burr-free finish when cutting thin aluminum, brass and other non-ferrous metal extrusions. A high tooth count with a 5° hook angle allows the teeth to slice efficiently through the material without binding. The requirements on the cutting edge greatly differ with nonferrous metals than with cutting wood. With this in mind, Freud formulated a special carbide with high impact strength for this blade. Freud recommends use of a liquid lubricant when cutting non-ferrous materials. This can be accomplished with a spray of WD-40 or other similar type of lubricant every 4 or 5 cuts. Wax sticks are not recommended.
