Appreciation post: Switched from a 4-flute to a single-flute endmill for aluminum after seeing a 30% cycle time drop on a test run.
The shop foreman in Tacoma said 'less flutes, more chip clearance' and after running the same part, the single-flute just plowed through without loading up, so what other 'old school' tool choices actually work better now?

Yeah, that tracks. We had the same fight about using brazed carbide tools for roughing out big pockets in soft materials. Everyone moved to indexable, but sometimes the old solid tools just hog out material without the chatter. What about using a stub length drill instead of a jobber for deep holes in aluminum? Less flex means you can push it harder without walking.

My uncle ran a job shop and swore by using a hand-ground HSS form tool for a specific radius on brass fittings. Said the CNC guys would program a ball nose and wait forever. He'd chuck it in the old manual lathe and have a batch done before their tool change. Sometimes the fancy path isn't the fast one. Ever run into a job where manual tricks still beat the programmed cycle?

That logic falls apart with modern toolpaths and high speed spindles. A good CAM program with optimized cycles and the right tool will smoke any manual process for repeatable parts. The real time sink is always in the setup, not the cut itself.
