#19 Jobber Drill Carbide Tipped 118° Standard Point, USA Made, Number 19 (.166"), 50372

My father is a retired machinist with a lot of experience. I bought this for him. He needed this to drill 3 hours. The tip broke on the 2nd hole.

Machinist neighbor said chrome was hard to drill. Bought this to use with a matched tap and used a smaller solid carbide bit to use as a pilot bit, all on a drill press stand. Succeeded on drilling and tapping the two holes I needed to reconfigure my globe.
