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: Product well worth it no shabby metal, another happy hubby - Bought this for my husband as I always buy on desertcart and he was so happy, it fit perfectly on his drill and having all different sizes all at once was like candy in a candy store, the price was amazing and they were super easy to use, the metal is strong on product no shabby cheap stuff

## Features

Our set includes 2 pieces of each model, 12 pieces in total When one is damaged, you can easily replace it to avoid not having the same size model and delay the maintenance work.
- [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.
- [Carry and Store Easier] 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.

### ⭐⭐⭐⭐ Needs a 5/16 in the kit but works very good and saves time.
*by J***E on June 17, 2025*

Work very well, wish it had a 5/16 in the package. Make sure if you holding the tubing with your hand you use a wet rag cause it does get the brass hot.
