This set contains the commonly used metric threads. Great for cleaning up metric threads. Must have for auto / maintenence mechanics' toolbox.

Perhaps these should be entitled "bottoming taps" as the initial cutting edges are very hard to get started in a drilled hole. Most taps have slightly tapered introductory cutting edges to allow the threading to get started. These taps start at full surface, making it very hard to get them started in the tap hole. I ended up with blisters on my hand from pushing so hard to get them to take. Perhaps they would work better on a drill press (to provide downward pressure) or in some device that applies pressure while turning.

I needed to add threads to the floor blank blind rivets in my lincoln navigator to install the middle jumper seat. This set had the two sizes I needed and they worked well with just turning by hand. 1/2 trun then back off and go forward again. I used BP blaster oil for lubrication.

Theses taps are very low quality and only have 3 flutes. Definitely not for professional use or for a job that matters.

The first thing I did was start in on my bicycle. I needed some threads touched up. I was able to do this 'touch-up' with very little trouble. I made certain the bits were well lubricated. They showed no wear (did two M8's and three M10's) when I was finished. I was aware when I ordered this set that it did not come with a bit-wrench. I was aware but still a little annoyed. Meanwhile, a small adjustable wrench rotated the bits satisfactorily.I suspect these bits are low-carbon steel which means two things:They will rust easily. If you keep them lightly oiled, this should not be a problem.Being a softer metal, the bits will degrade more quickly and require replacement.Me? I'm satisfied with the price. I think I got my money's worth.
