Description of Forney 20238 Letter 118 Degree Jobber: Precision and Efficiency Combined
Drill bits are surface treated with 118-degree point. For general purpose production drilling. Materials such as cast iron, steel and steel forgings. Steam oxide finish and surface treatment. Provides abrasion resistance and improved chip flow.
Haven't used the tool yet so can't properly assess the work. However, the bit I received was made in Brazil, even though the dates on the tool say it was made in the USA.
So it's a drill and it works. I used it to drill a hole in my cast iron exhaust manifold for a temperature sensor that required a 1/8 NPT thread. If you do something like this, this should work.
F-bit needed quickly and Revain delivered. Does exactly what I need and drills a nice .257" diameter hole. I've used it for slow speed drilling in mild steel and did exactly what I needed. I'm a shop mechanic with occasional drilling needs but can't commit to commercial/ express professional applications and needs.
Pros
Materials like cast iron, steel and steel forgings
