Not suitable for use in aluminum

They may be suitable for wood and other soft materials, but in aluminum I only have 1 or 2 taps of sizes M3 and M4 respectively. M3 broke on tapping on the second hole, M4 broke on tapping on the third hole. It was aluminum 6061 with a thickness of 2mm. Either go for a better quality tap or do like me and switch back to separate drills and taps.

Pros
  • Widely used
Cons
  • I don't remember but there was something

As expected! Very good product!

This is a great product and does exactly what it is supposed to do once you know how to use taps. They have been used a few times so far and have worked great. Obviously you need to be more careful when tapping on wood as it is softer and if you don't take the time to unscrew the bit you will ruin your tap. Again, if you have the know-how to use attachments, that's GREAT :)

Pros
  • Quick Change
Cons
  • Slightly Torn

Defective hand tools and hand tools

I only ordered a set of 6 so I can't confirm what others have received but 3 of the 6 I received had serious sizing errors from the manufacturer on the drill bits.

The first photo shows the "unintentional" ground planes (both sides) on the leading edge (cutting edge) that DESTROY the bit's ability to drill holes. These flat points should NOT be there. In the second photo you can see that this side of the "back angle of the terrain" is not a…

Pros
  • High quality material
Cons
  • Cord is shorter than other picks
