Does the tool produce any kind of soot, impurities or metal shavings inside the tube?

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.
