OMGA T 521 ST Pneumatic Up-Stroke Cut-Off Saw
The T 521 ST is OMGA's pneumatic, adjustable-speed pop-up chop saw. The blade strokes up pneumatically, and the workpiece is clamped automatically in cycle with the blade stroke. OMGA says the clamp also acts as the blade guard, and it rates the saw best for length cutting and defect removal.
Its brochure adds that a 10° tilt keeps the piece correctly positioned against the fence. On request it can be fitted with infeed and outfeed roller tables with scale and manual or pneumatic flip-over stops.
Power and air
Three phase, 230V or 460V on our store. The blade stroke and clamp are pneumatic, so the saw needs a compressed air supply.
