Sawing is one of the most versatile and used tube cutting methods. It enables the work with high production volumes, provides a clean cut (but then typically polished by deburring) and is cheaper than the laser..
This system is especially suitable for cutting small diameter tube or thin-walled tubes, which require close tolerance range (a measure refers to the cutting accuracy), producing a minimal burr. Being a cold cutting process (cutting zone is cooled with soluble emulsions in oil or synthetic oil to prevent blade teeth softening), it produces no heat affected zone, which can be a benefit for products requiring subsequent finish.
Tube cutting with circular cold saw gives a much better finish than bandsaw cutting, and enables to work with higher volumes of production simultaneously . This is very useful in small tubing, allowing batch cut and making the process profitable.
Furthermore, tube cutting with circular cold saw make possible a greater variety of cuts (straight, grades, in short pieces, in large pieces, etc.)
Bandsaw, however, is suitable for large and thick-walled tubes that do not need a perfect finish, since these tubes are very complicated to deburr after its dimensions. In addition, it is cheaper.
