Corkscrew milling literally takes a new approach to cutting pockets? So much so that Baldor Electric of Gainesville, GA changed up their strategy of using large diameter twist drills in favor of ramping an endmill down in a corkscrew pattern. A one part experiment turned into a new production method now used on multiple parts across a variety of motor housings. Read the rest of the article here.

Interesting… but I’m not sure I have the balls to try it.
This kind of milling is revolutionary, it cuts down machining time significantly. Not hard to program I’m a college student and we do this
I’ve never done anyting but helical interpolation (corkscrew). Ingersol hi positve at 30% diameter z ramp in steel and let it rip at normal sfm, just make sure to get some good air in there to get the chips out and make sure the tool is sized to the hole so it doesn’t bottom out (between the cutters). Much more gratifying than drilling.
