Trochoidal millingis an efficient way to cut a slot other than using the standard slotmilling method. Introchoidal milling, an endmillis used to machine the slot width using a circular movement. This is called thetrochoid method. It's an efficient way to produce slots using high-speed machining methods.Trochoidal milling

Drilling - HSS 70-125 SFMDrilling - Solid Carbide Drills - 300-450SFM (Carbide insert drills can run a lot faster. Anywhere from 500-1200SFM)Turning - HSS 70-125SFM (This one is questionable though. I don't cut with HSS at all)Turning - Carbide 600-1500SFM depending on gradeMilling - HSS End mills 70-125SFMMilling - Carbide End mills 300-1000 depending on coating.

The general rule here is carbide is superior to HSS in most cases. If you get into softer materials like aluminum and plastic, a HSS endmill could do better.
