12Pcs HVAC Repair Kit, Air Conditioner Tube Expander Swaging Tool, Manual Pipe Swage Tool With Expander Boring Drill Bits for Soft Copper Tubing 1/4'' to 7/8''

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

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.

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.

Don’t work as good on anything above 3/8” as it does on 3/8”

The small ones worked good but the larger ones didn’t swedge the copper very well

If I could do 0 stars I would,first time I used it in snaps in half do not buy this Chinese BS

Tal como se describe el producto vale realmente lo que pague hasta ahora están en uso

Muy bien
