Deburring Copper Pipe Internally

What happens here

After cutting a copper pipe, the internal edge often has sharp, uneven metal protrusions called burrs. These burrs can impede water flow, create turbulence, and potentially damage O-rings or other internal components of a fitting, leading to leaks or reduced system efficiency. To remove these, grasp the deburring tool (referred to as a 'pencil reamer' in the video, specifically a REED brand tool) and insert its curved blade into the pipe opening. Rotate the tool firmly around the inner circumference of the pipe, applying slight pressure. As the tool rotates, it will shave off the burrs, creating small pieces of copper filings. Continue until the internal edge is smooth to the touch, and no obstructions are visible. The video first shows the smooth, deburred pipe, then the burred pipe, and finally the action of deburring.

Goal: Remove internal burrs from a freshly cut copper pipe to ensure smooth water flow and proper, leak-free fitting with plumbing connections.
