After tubing is cut, how should burrs on the cut end be removed?

Reaming is the correct method for removing burrs on the cut end of tubing. This technique involves using a reamer, which is a specialized tool designed to smooth out and enlarge the internal or external diameter of a tube. When tubing is cut, particularly in metal or plastic, sharp edges or burrs can form, which may affect the fit and function of the tubing in its application. Using a reamer effectively smooths these edges, creating a clean finish that helps prevent damage to components that will be fitted into or onto the tubing.

Filing, while it can remove burrs, is typically more suited for flat surfaces or less precise applications. Sanding could also be used but tends to be less effective for achieving the precise finish required in many tubing applications. Cutting again is often not ideal because it could create additional burrs rather than removing existing ones and would require further finishing work afterward. Therefore, reaming is the most effective and recommended method for this task, ensuring a high-quality finish for the tubing.
