A tubing cutter is a specialized tool designed to cut through various types of tubing, such as metal or plastic. It typically features a circular blade that rotates around the tube, allowing for a clean and precise cut. Tubing cutters are commonly used in plumbing, HVAC, and automotive applications, making them essential for professionals and DIY enthusiasts alike. Using a tubing cutter is straightforward. The user places the tool around the tube, tightens the knob to secure it, and then rotates the cutter around the tube until it slices through. This method minimizes the risk of damaging the tubing, ensuring a smooth edge for further connections or fittings.
