The quick take
The short version of why each pick lands where it does, built straight from the measured results.
“A very affordable Cobra drill bit set came in on top with the best average finish of 1.6. The Cobra drill would definitely be my choice, and it's a terrific deal for M42 cobalt bits at less than $40.”

How it was tested
- time to drill through 0.5 in mild steel plate with a drill press, initial pass
- time to drill through leaf spring steel (about 0.375 in), initial pass
- repeat 0.5 in mild steel pass to measure speed loss after the spring steel test
- repeat spring steel pass to measure further durability and speed loss
- time to drill through AR500 armor plating
- overall average finish ranking across all speed and durability categories
