Works

Used the 1/4" and 3/8" on a small refrigeration project and sort of worked OK.Built up a lot of heat during the process.Tried the 3/4" & 7/8" on soft copper lines and didn't work at all.Reamed the tubing prior to trying and "no go" and also heated the tubing to a point I couldn't hold on to it.

Used them once in my Dewalt impact to find that the shaft is roo short & the metal is getting chewed up ...maybe they would work better in a drill which means I would have to tote another tool around.

Cheap material

Bit ended up snapping upon use, finger/finger nail was cut clean through.

The material on the bit is to thick and blocky that it doesn’t not properly make the fitting. Bad product do not recommend.

Two of them broke off in the chuck of the impact got the 1st stub out but the 2nd one will not come out of the chuck had to buy a new impact not worth the money to have to buy a new impact every time I should have them send me the $139 for the new impact lol all I can say these are junk
