- 【Working Principle】 When connecting the copper pipes of the air conditioner, the soft copper pipes are expanded by the rotation of the drill bit, so that the two copper pipes can be connected in a leak-proof manner. Works more efficiently than round nose reaming tools when combination with drill and impact drill. (The drill speed should not be too fast)
- 【High Quality Material】The drill bit is made of ball bearing steel, with high strength, not easy to break, wear-resistant and durable. The curvature of the flare allows the drill to gently expand the copper tube to the specified inner diameter.
- 【Easy to Use】It is very suitable for HVAC installers to perform air conditioning copper pipe expansion operations without complicated learning. (Please wear anti-scalding gloves, goggles and other safety protective equipment during operation.)
- 【Easy to Carry& Store】 Compared with other copper pipe flaring tools, our drill bit set can be carried with you or placed in the tool box, it does not take up the volume, and it is easy to carry and store.
