Time saver
Great product. Holds edge very well. Drill through stainless steel plates with no problem.

Hard, sharp flexable
Hard, sharp yet flexible enough to resist breaking when pressed. These bits drilled my watch lugs through for shoulder less fat pins.

The best
So glad I finally found these as I've tried nearly all the other micro metal drill bits Amazon offers and these are the best. Totally worth the cost and so much less frustrating. The others dull quick and break even quicker. These will still break with pressure so be dainty but far better than others I used. The Best there is....so far.

Tough Bits for a Tough Job
I am drilling multiple holes in 1" 304 Stainless and these bits have held up quite well. I like having 10 so I can rotate through them as I go. Significantly better that anything hanging on the wall at Home Depot or Lowes and much cheaper. Getting ready to order another 10.

Does what a drill is supposed to.
Pack of 10 drill bits is appreciated, as 1/16" bits tend to break a lot.
