A tool like this could use some instructions since it's not something people use every day. These didn't come with any. I have experience using taps, so it wasn't a big deal for me. No guidance given on what size drill bit to use for each tap. I used AI to figure it out and ended up buying a numbered drill bit set, since standard drill bit sizes are not made to match the tap sizes.Taps were sharp and threaded my material (galvanized steel) without a problem. Not compatible with standard drill bit sizes so make sure you have the correct drill bit sizes in your tool bag. I can't say how durable they are since I only threaded one hole but the quality seems good they seem to be a good value.

Worked great just be gentle these are very small items. I used it to install trigger stop screws in some of my air rifles

[Size: 1/4"-20 UNC Tap & #7 Drill]
Worked great on 1/4" 316 stainless steel plate. Had to go slow but very nice threads. The bonus was it coming with the drill bit.
