Ryobi bits are the worst. Some will immediately break. The bits with open ends to fit other bits aren’t even to size and the bits you put in them aren’t snug and will fall out. First time any bit goes off the track it immediately strips. Some just break on light usage. The steel just breaks in half.

I presume instead of coal coke for carbon, they substituted shit, which while it does have some carbon produces an inferior product.
