Features
- [6 Pipe Sizes] 6 different sizes of drill bits, including 1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1/4" hexagon handle. Our pipe expansion tool are an essential accessory for servicing air conditioners. 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. Tip:If you have any questions, please contact us, we will give you the most professional service!

Bought this for my husband as I always buy on Amazon 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

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

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.

The plastic case came broken out of the box. More importantly, the 7/8" bit bent on first use. I know this set is proved a lot lower than the sets from the big hardware stores or HVAC distributors, however, I was hoping to get more than one use out of the bits

My husband bought this to use on a job as a plumber- expanding a copper pipe. He said the boring bit fit perfectly into his drill and worked exactly how it was supposed to. The bits are easy to use. He only needed the 3/4” piece for work but the set was such a good deal and came in its own case for easy storage in his van. The set is made of thick metal and looks sturdy and strong. I was surprised how heavy this set was. He got the 6 piece set. One thing he said was how expensive these individual boring bits/sets are in store and how good of a deal this set is. He didn’t want to buy an expensive set bc he’s never needed this tool before and it’s unlikely he’ll need it again. Husband said he recommends this set but emphasized he’s not using it constantly or in ways that really push the boring bits to the limit.
