Introduction The FK350 and FK350-SX are circular saws designed to provide a reliable solution to the needs of machine shops and production environments that work with steel or iron. The FK350 is manually operated: after clamping the material in the vise, the operator presses the trigger handle starting the blade, and brings the operating lever downward to cut the material. The SX offers both semi-auto and manual mode. When in semi-auto mode, operator positions material, and then presses the

Features Miter Cutting Head The miter cutting head is the unit that cuts the material and consists of a cast iron base, blade support unit and guard, transmission unit, and motor. The depth of cut is set by adjusting the depth cut stop. The miter cutting head swivels and locks into -45º, 90º, and +45º by means of a locking mechanism. Depressing the mechanism overrides the lock, permitting the head to adjust Figure 1 to any position between -45º and +45 . Flood Coolant System Miter Po

Blade Structure For non--ferrous metals, it is common to use circular saws with brazed hard metal HM cutting edge, consisting of a disc made of alloy tool steel (71Cr1) on which the shape of the teeth and the seats for the cutting edges are made of Widia K10. These saws have shown excellent wear resistance but low resistance to impact, which is in any case a minor problem with non- ferrous materials.
