Review on 🔩 Bosch CO2155 Cobalt Drill - A 5-in-1 Powerhouse by Jason Camarillo

Bought this bit to cut through a broken grade 8 bolt. In case you didn't know, a grade 8 bolt is incredibly hard steel and is easy to machine eat with HSS drill bits for breakfast, lunch and dinner. As the name Bosch does not suggest otherwise, the drill is manufactured and milled with very high precision. Very sharp out of the box and after drilling out the grade 8 screw it's still in great condition. If you have very hard metals to drill, this drill bit can do it in the right bit.
