Worthless for precise projects

This industrial and scientific drill bit is an absolute waste of money. With it being uncalibrated, it's impossible to get accurate measurements, making it worthless for precise projects. One positive aspect is that it's made of quality material. However, this doesn't offset the uselessness of the product. Don't bother purchasing this item if you're looking for precision.

Pros
  • Produces precise and accurate threads in various materials.
Cons
  • Requires skill and experience to use correctly, which can lead to mistakes and damaged threads if used improperly.

Broke on first use, suitable for power tools and hand tools

Used a tap, and when I used it for the first time, three drills broke. I ended up going to HB and buying a few to actually complete the job.

Pros
  • Updated plastic packaging. （6.35mmοΌ‰,5/16"（7.94mmοΌ‰,3/8"（9.53mmοΌ‰

Useful tool for sheet metal work

Drill bits work well on thin soft metal. Haven't tried anything else. Use an electric drill to cut a hole, and then use the drill to carve the threads into the metal. Suitable for cleaning nuts from dirt or rust.

Pros
  • Suitable for materials with low hardness such as wood, aluminum plates, plastics or iron sheets (thickness less than 3mm).
Cons
  • Not sure
