Review on 💥 Enhance Drilling Efficiency with Drill America DEWCSCBR6 High Speed Counterbore by Tyler Owens

Didn't use it at first. The one I used survived the 220 holes I had to countersink in the mild steel rods I milled. So once I start using it I'll update my answer. The only disappointment is that the tool does not have a pilot diameter hole. This is useful from time to time when the pilot is just not filming.
