I have many drill bits, from very expensive American made cobalt bits to these Wen bits. I bought these for work where I don't want to risk my best beats or when my neighbor needs to borrow something. They're not as good as the $100 set, but for the price, they're great. They cut fast and have a cleavage point and work great with mild steel, wood, plastic etc. They beat most of the 'usual suspects' like brand name shops or even Dewalt. Highly recommended for what they are.
