Don't worry if you use this on metal work.

Attempting to cut 1/8" thick steel. This bit was deformed and became dull. Yes, I used lube to keep everything cool. I wouldn't use this on anything other than wood or plastic I'm glad it wasn't as expensive as regular bits, I guess I'll just bite the bullet and buy a regular one for $50-$100.

Pros
  • Light drilling
Cons
  • Small parts

Revainrating 4 out of 5

Replaces many drills.

This is my third set of these bits. They are useful for enlarging previously drilled holes. Bought the last set as my nephew borrowed them to drill a 1/4" panel. Handy for quick drilling instead of wasting time just finding the right size drill bit. No, these aren't expensive hardened drill bits but they do a small job I need to drill buy a set they need a tool from time to time

Pros
  • Included
Cons
  • Expensive

Not for use on metal

Terrible quality. I used these bits to make holes in the side of the channel to fit my scissors. I pre-drilled the holes so as not to damage the tip, but even with that they dulled enough to fit the canal after a day's use. The pipeline wasn't too heavy. Port Freight has a much better quality Staggered Nozzle and that is saying a lot because Port Freight usually has poor quality tools.

Pros
  • KIT INCLUDES
Cons
  • Not sure
