Good quality, I'm using these on automotive and they are sharp and work as expected

Good product great value

Bought as like new/ The case was broken, but they looked new so. They work better than titanium drills. Use drill oil.

Quality and tough long lasting drill bits

Great price. Works as expected

Great! durability is good, right size, not complaints!

Good quality

These cobalt bits are great for hard steel.

I build vintage race cars, I’ve got a dedicated 1/8” drill because it’s used so much. We’ve tried all sorts of drills, because we work with aluminium, steel, stainless, brass it’s hard to find a bit that will do it all. I cannot fault these at all and for the money you can’t go wrong. I’ve paid this price for 2 bits before from a major brand and they were hopeless for multi metal. Im deffo going to buy again and check out other sizes! I even run these in the lathe and pillar drill/mill now.

Bits performed poorly on ferrous steel and the top of one sheared off while drilling. Might be ok on softer metals but failed to meet even minimum expectations on a piece of u-channel sign post.

jamais recu

Excellent drill bits,have used three of them extensively over a two week period.Have not broke one of them yet.

These wouldn’t drill butter. First 4 were totally blunt as if had been used. The 5 worked ok but blunted not long after. Will stick with Bosch next time.
