  • Machine taps are suggested to be used with tap collets with overload protection. Hand use or electric drills use is easy to cause breakage to the tap, so it is not recommended.

I used these threading a set screw hole and unfortunately one of them broke. I was using it in a drill which I know I should not have been but when I used the other with a tap handle it worked great

This two-pack of 1/4 X 20 taps was a really good deal here on Amazon. I got these to replace the tap that broke in my Hanson kit after a good amount of use. These taps are decently made from high-speed steel and are holding up well, so I think there were a good buy.

I very rarely write one star reviews but I would stay away from these taps. Mine snapped on its first hole in 1/8" thick aluminum. Its garbage at least in my sample of one. I will get another somewhere else before I use the second tap that came with this as this ruined the piece because the tap is stuck in it.
