r johnson: I needed to drill through a steel weld and burned up a bunch of bits just trying get a pilot hole. I chucked up the 6.5mm bit from this set and squirted some 3 in 1 oil on it and she blasted right through it. I could care less about the case, THAT'S IMPRESSIVE!!!!

Eddie Robinson: I like the fact that were as described and of great quality

manuel a: They don't seem to be very sharp. I might actually return

Spake1: Cuts through stainless ok and I haven't snapped one yet.

Philip: Drill bits seem well made. The case…not so much. Mine came so cracked I barely holds the bits in.

ken: I want to use these to drill rivet holes for 1/8" pop rivets. The holes are too small. Comparing sizes using a digital caliper, the size in mm is 3.15. The 1/8" drill bit measures 3.14mm when directly comparing back and forth twixt the two numerous times. The rivets read ~3.18mm. I use comparative readings as I do not have a micrometer. I compared the bits against a half dozen imperial bits from different manufacturers and got similar results. Therefore I believe these bits are undersized.

JWJW: At the time I purchased these, I only intended to use them for light duty (drilling into polymer). However, as fate would have it, I had to use them to drill into hardened steel, and much to my surprise, they performed admirably. It was a pleasant surprise (I was expecting "Chinese junk") and I'm very happy with this purchase; especially considering that it's a METRIC set, which is difficult to find (in the USA). I wish the set had a 1mm bit, but oh well. It's just a preference, not anything against the quality of the bits in this set.

Update 1/16/18
=============
My rating has changed from 5 stars down to 3. I needed to drill into metal again--actually I wasn't even drilling new holes, but just "chasing" already existing holes to expand them--and neither the 4.5mm or 4.8mm bits would do anything. They just spun around getting hot, without cutting anything. I even tried the 5mm bit, even though that was too big for my purposes, and it also did nothing but spin. Thus, I've used four of the bits (4, 4.5, 4.8, and 5mm), and only one of them did anything. The one that actually worked did its job well; the others are a HUGE...
