Review on Bosch CO2135 2-3 Cobalt Drill Bit by Icehot Cleversley

Needed to drill some steel rivets and the other bits in my arsenal didn't fit. Ordered this and the 1/4" size and they worked like clockwork. I didn't use lube because I was cheap/lazy and worked really hard on these rivets - no breakage, little wobble, vengeance or anything of the sort. of these bits .They seem excellent and I will definitely buy from Bosch again if I need other sizes.
