Subsequent to my post, I too have been experimenting. My grabby problems are definitely exaggerated on larger diameter drills to where they can become planted or wreak havoc with the tailstock chuck/MT arbor. I also realized under magnification that my 'new' HSS drills are razor sharp & have an ever so slight curve on the lip. some kind of funky grind (still a 118-deg point). They are well made, cut steel like a damn, but just asking for trouble in the 'B' materials.
I took a 0.375" drill & did a test hole in my C932/SAE 660 bronze, 544 bronze and C360 free machining brass. That was also the order of 'grabbiness'. I then dubbed the same drill like what is shown in Clickspring video. Nothing else changed. Same spot drill, same speed & feed. And the difference was like night & day. It just walked into the material like it was a completely different alloy. I felt like a small miracle had occurred. So I dedicated some larger progressive drills to this dubbing treatment & I am going to get a set of reasonably priced HSS, dub them all & leave them reserved for this type of material.
