Sharpent drill bit in town
Spent 21 years in the military and used the split point cobalt to drill many hard metal including inconel steel, & Titanium for F-4 engine bays!! Bought many to be prepared for the future.

Like split point cobalt for all hard metals.
Used them in my 50 years as a metal worker, great for drilling hard metals, makes it easy.
