Review: Always reliable and holds an edge - So much better than the less expensive bits I’ve always purchased.
Review: great bits for the price. go through 3/8" sheet steel like butter, and with cutting fluid they held up great so far. - used with some truetap cutting fluid and a Milwaukee d-handle drill from the 60s to drill multiple 5/16, 3/8" holes in 3/8" steel plate and slightly thinner angle for mounting a winch to an F250. These were great, I will never use anything but cobalt, and these Irwin were awesome for the money. I wished it would have come with a 1/2" bit but other than that, super solid buy.

*by M***V on November 30, 2016*

### ⭐⭐⭐⭐ Expensive but functional
*by C***R on January 5, 2017*

Sturdy case. Drills seem sharp and hard enough not to dull on soft metal drilling. I like the multiple pieces of the smaller -- more easily breakable -- drill bits. I dinged one star for the expense.
