Features of the Flaring tool drill bit set

The drill bit tip is designed to fit a drill, allowing the refrigeration tube to be flared for adaptation to the SAE brass fitting. It is made from hardened steel, thus providing great resistance. It molds the tubes through friction heat. This flaring drill bit set includes the following sizes: 1/4, 3/8, 1/2, 5/8, 3/4.

Additionally, it comes in a plastic case, equipped with a screw-on lid for better protection and preservation. We recommend its use with drills operating at 1800 RPM and having a power of 500 W. For cordless drills, a minimum of 18W is suggested. It provides flaring much faster compared to traditional tools.
