DescriptionThe air conditioner pipe expander tool is made of bearing steel with high hardness and strong toughness to ensure that it is not easy to break and deform under strong torque. The surface is blackened, heat-resistant, wear-resistant, corrosion-resistant and rust-resistant, with a long service life and safe and convenient use.
Our 5-in-1 drill bit set can be carried with you or kept in your tool box, taking up no bulk and making it easy to carry and store. The hexagonal handle is used with an electric drill to easily expand the copper pipe, efficiently and quickly, saving more time.
The electric drill tube shrinking tool can not only expand the copper tube, but also expand the tube mouth function, 5 sizes of drill bits, suitable for most copper tubes, helpful for air conditioner repair, refrigerator repair, copper tube repair and so on.
Since the copper tube and the copper tube expander will generate heat when rotating and expanding, please do not touch them directly with your hands. Wait until the copper tube cools down before operating to avoid hurting your hands.
