Title: Not worth $60
Review: I had my set for couple weeks now and I have already broken a bit. The material is very brital. While drilling steel the bit broken in half. I also discover that the tip surface is not exactly even/symmetrical which results in your work piece wobbling on initial contact. Once the bit digs into the work piece the wobbling stops. I compare this wobbling affect with a USA made bit and there were zero wobble with the USA bit. These bits are sharp and will go through steel like butter. Overall I am not happy with the purchase. I would return it if I hadn't broken a bit. It was a waste of $60.
