Super Duty Metal Cutting Series Radial Arm Saws

NON-FERROUS
Cutting non- ferrous material such as aluminum, copper, soft brass, ect. Is done very effectively on Original Saw Metal Cutting Series machines. When choosing the proper blade take a look at the wall thickness on your material being cut (typically extruded aluminum). It your wall thickness is under 1/8” you may want to consider a high speed steel blade versus a carbide tipped blade. There is more to deciding than just wall thickness particularly stiffness and shape of the extrusion, if you have a thin wall and a flat area that may allow flex when cutting the wall may chatter during cutting and chip or break the carbide teeth.

Our machines coupled with the use of the proper blade will result in very good quality cuts. Carbide tipped Non-ferrous blades of this type would generally use a slightly softer grade of carbide tooth in a C-2 or C-3 carbide to take the impact of cutting this type of material and a triple chip grind as well as a negative 5o degree hook angle. Using this type of blade will reduce or remove the chance of the blade grabbing the material and provide a very smooth cut finish. On extrusions with a thin wall we recommend a high speed steel blade with approximately 250 to 300 teeth. In most non-ferrous cutting applications we recommend a mist coolant system (see accessories page) This coolant system will greatly extend blade life and cut quality. Not using the coolant will allow the blades gullets and teeth to “clog up” with material and require more frequent sharpening.
