Review on 🔋 POWERTEC QDB2013 16 Inch Cobalt 135° Superior Drill Bit by Ryan Saxton

August 28, 2022

For longer drill life choose cobalt

I have been using cobalt drills for over 20 years and these 1/16 inch cobalt drills offer the best quality for the money. I have continued to break HSS and TiN bits when drilling wrought iron and 304 stainless steel on the drill press, but not a single bit has broken since switching to cobalt.

Pros

jobber drill

Cons

not as thick as other drills
