Developed for production applications which require accurate high speed cutting of ferrous and non ferrous material such as steel, aluminum, copper and other material such as plastic, fiber glass, resins, ect. Smoothly cut surfaces are achieved at any combination of miter and bevel angles, Use of the optional mist coolant system, is recommended for maximum blade life (cutting non-ferrous material only) while maintaining smoothest, highest quality finish. 16" Models Catalog # 3579-16M, 3579-16L 20" Models Catalog # 3579-20M, 3579-20L 22” Models Catalog # 3579-22M, 3579-22L Standard Features Totally Enclosed fan cooled 7.5 hp motors all 3 phase units available in 208/230/380/400/460/575 voltages.

		Motors - All Super Duty, Heavy Duty, and Contractor Duty Series motors are manufactured in our Northern Iowa facility. Producing our own motors allows us to uphold a very high level of quality in our machines. These totally enclosed fan cooled (TEFC) motors are manufactured with cooling ducts that move air through the motor laminations to keep them cool while keeping the internal portion of the motor sealed from dust and contamination. These motors also offer the added benefit of an integrated electro-mechanical brake system, these brake systems continue to operate even when the power drops out. Electronic brake systems, cannot compete with the durability or reliability of our electromechanical brake systems.
		Cast Construction - Original Saw Company’s Radial Arm Saws are manufactured utilizing high quality heavy cast iron and cast aluminum construction. These high quality American castings provide a very rigid, vibration free cutting platform to perform many different sawing and dado operations. It is because of this construction, we can proudly say our machines are the best in the industry. Many of the machines we produce today will be around for generations.
		Carriage Control - The metal cutting series comes standard with a manual chain feed assembly. This feature gives the operator better control of the carriage versus pulling the carriage by hand.
		Guarding - Shown left is the Metal Cutter’s exclusive “door style” guard that allows easier and quicker blade changes, the guard needs only to be opened not taken off to change the blade out. This is a very important feature for the ferrous cutting application where frequent blade changes are necessary for optimum cutting performance and safety.
		Table - The Metal Cutting Series comes with the standard t-slot aluminum extruded top. This top allows for easy attaching of our aluminum fence (shown), clamping systems, or table surface options, as well as your own clamping jigs or cutting fixtures. These all come mounted to a extruded leveling frame for easy leveling of the entire table assembly through out the life of the machine.
