Final answer:
In HVAC installations, a reamer is used to de-burr copper tubing to ensure a smooth inner surface, which prevents fluid or gas flow issues and avoids damaging the system components.
Step-by-step explanation:
In HVAC installations, when working with copper tubing, a reamer is the tool generally used to de-burr the inside of the tubing after a cut has been made. A reamer is essential in ensuring that there are no sharp edges or burrs remaining that can impede the flow of fluids or gases, cause leaks, or damage other components in the system. It's important to distinguish between the tools used in this setting, as a flaring tool is used to flare the end of the tubing for a connection, a tubing cutter is used to cut the tube precisely, and a compression tool is used to secure a compression fitting to the tubing.
