I will try a setscrew holder again with one of my carbide endmills, David. And maybe a longer-arm Allen wrench.

I was not happy about the endmill creeping out the last time I tried but will trust your report!

My 1/4" ball-end is a 3-flute and I really like it, 300sniper. I hadn't thought of trying 3-flutes for flat machining though. Next time I need to restock I'll try a couple.
