Cobalt Drill bit
Would RecommendI tried to drill the head of a frozen bolt to use an easy out extractor and it dulled my titanium bits and other bits and even broke a bit. When I tried to drill into the bolt head with this cobalt bit it bit right in and drilled a hole into the hardened bolt head like it was wood. Very impressed with the strength and sharpness of this cobalt bit.

Rips right through metal
Would RecommendBought this bit and another to finish a project that needed metal modification. This was totally up to the task and ripped straight through the metal band.
