Drills are rust free! best in category drill bits

Indispensable for drilling stainless steel. All the bits I have, titanium bits don't fit! smoke and don't look for a bite! that's good for what i have to do so far. They may not be the most expensive, but they work! While they appear sturdy, I haven't used all sizes yet!

Pros
  • power tools and hand tools
Cons
  • obsolete

Do what you're supposed to do

Used these to drill out the heads of some stripped screws, these things held up so well they pulled the stripped screws out completely without breaking them (yes I have them accidentally turned into reverse. Shut up, it was still working). Great product, definitely recommend.

Pros
  • power tool parts and accessories
Cons
  • old

Works but requires a small push in metal

Works but requires a small push in metal. Bought to drill a U clip to attach the metal guard to the outside air extractor hood. I think it worked like a charm and made clean holes easily but the husband said he had to get used to drilling metal first and after that he made clean holes and managed to do it in 5 minutes. bam! . In other words, worked like a charm.

Pros
  • Spare parts and accessories for electric drills
Cons
  • Questionable purchase for the elderly
