Nice, inexpensive set of bits
Nice, inexpensive set of drill bits. They're not very long, so make sure you know what you're getting. They're nice to have as replacements for others that I have broken so they fit my need perfectly. I'm not expecting to drill through diamonds with them...

Good bits, poor quality box.
Bit’s are sharp and appear to hold an edge; I have only used two Bits out of the index and both worked well. Index box is thin and deforms easily, latch is not trustworthy. Good bits, poor quality box.

Pretty solid an durable
Well i broke one bit, but for the money they're pretty solid considering im going through cold rolled steel thats a 1/4" thick. Also, if youre going through any solid metal such as steel, dip the bits in oil at the tip to help with the heat

Durable and worth of money. These bits are seem very durable as far as the strength of the metal and they cut very well

Weak Bits
First time I tried to drill a 3/8" hole into a pipe with a cordless drill, the bit snapped in half on me. Not sure if the integrity of these bits can actually handle drilling through metal.
