Benefit: Less/no secondary work
The low cutting pressure allows the saw to cut completely through the piece for a clean, smooth cut. Thus, RSC virtually eliminates the cutoff nib and significantly reduces burr resulting in a better quality part. Furthermore, with RSC, tool and workpiece deflection are negligible; surface flatness and squareness are typically within .002" and often even within .001". This is still attainable while feed rates are 150% to 300% of single point cutoff rates, and without the assistance of workpiece supports. Length dimensions not only can be held to a very close tolerance, but can be repeated within tenths.
On the other hand, the high cutting pressure of a single point cutoff tool causes the part to break off leaving a large nib and excessive burr. Likewise, the same pressure limits the length of stockout over which multiple cutoffs can be taken effectively.
