## Description

Product description

Review: Works great and cheap - I got these for one job and they worked great. I wish there was no finish on the working end as that burns off on my copper line. So for that use it on a test or scrap piece to remove the finish first. Other than that works as intended
Review: Slick tool saves time, saves money, less to braze when installing or reparing equipment. - Amazing tool. It seems to work well. I'm glad bought.

- [High Quality Material] Swaging Tool Drill Bit made of ball bearing steel, it is practical and durable. It has high and uniform hardness and wear resistance, and high elastic limit, your good helper for work and life.
- [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)
- [Use Easier] 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.) The curvature of the flare allows the drill to gently expand the copper tube to the specified inner diameter.
