    Good overall with a small exception
    Overall these are great bits and MUCH easier than a traditional set. I was skeptical due to the price, but the threading is great on the 10-32 and holds the screw well in the threads. I haven't used the other threads. I also can't speak to the durability due to only having these for a few days. The only complaint I have is that they leave a slightly raised ridge where they start the threading. This could be operator error and I'll try to apply more pressure when starting a thread, but it's pretty consistent on each hole I tapped. If this was not a finished rack, it wouldn't be as issue and could be lightly filed down. However, this is re-threading a finished product so it would be difficult to file and paint without being very obvious.

    5.0 out of 5 stars Have tapped thread into small aluminum heat sink
    Reviewed in the United States on July 19, 2020
    For my small project I have tapped threads into small (40 x 40mm) aluminum heat sinks and then mounted an LED chip to the heat sink. The smallest tap worked great for this project. I have tapped 3 heats sinks and mounted 3 LED chips. So far these tap bits are working very good.

    I recommend starting with a punch, then the smallest drill bit you have. I used drill bit oil on both the small drill bit and then on the 6-32 tap and things went very smooth.
