Soot or even small metal shavings may occur during the use of both conventional tools and SPIN tools, due:
- The way the copper tube is cut;
- The quality of the alloy used in the tubing manufacturing;
- The sharpness of the tube cutter;
- The use of a deburring tool after the cut, etc.
Therefore, what is important in this case are the other variables influencing the soot/shavings production, not the type of tool itself.
It’s important to pay attention to the cleaning routine according to the manufacturer’s manual as well as maintenance instructions.
