Review on 🔩 Economy Reduced Shank Drill by Drill America Qualtech by Chris Long

Totally blunt before first use. When I first tried using it, there was already a 1/2" pilot hole in mild steel, so I could thread up to 3/4-16. Just the metal polished, nothing cut. 40 turns in a 750 drill press and a back cut and it went through the material like clockwork. Went 2 inches deep in about 1 minute or so with plenty of zep drill bit coolant. I just wish it was already sharpened. Also, as I always do with bits with such a long reduced shank, I cut it short enough to fit in the drill chuck. I find the reduced shank very easy on large bits like these bends. This punch was no exception. It seemed that after trimming the beating was much less.
