It broke on me but to be fair you take a risk each time you use a drill instead of a tap/die bar.It cut through thin gauge steel (my original reason for buying it) without tap fluid easy.It made it through 10 out of 12 deep aluminum holes with fluid before snapping.To be fair, and hence my 5 star, I knew the risk from using a drill for it and it was an afterthought. Some slide/rail parts I got only had half of the holes tapped for whatever reason, and I noticed they were 10-32 so I finished em with this guy.If I had an originally bigger purpose for purchasing, I would have paid $10 for a solid tap bit, but since I initially bought this for literally 4 tiny holes, and it was $3, I'll give it 5 stars
