I own and have used a variety of countersinks, most are Keo and Melin. Single flute, multi flute, zero flute, cobalt, HSS, etc..in 82 and 90°, which is what I use most often. Size range from 1/8"-7/8".
Using slow speeds, I get the best results but sometimes I get some chatter which results in munged up countersink op.
What are you gentlemen using that gives the best results? in steel and non ferrous materials. I use mostly tool steel, mild steel (1018 1041), aluminum, bronze, copper and brass. what works best with what? I try to countersink right after I drill a hole to keep things lined up.
