💡 What is an end mill used for in CNC milling and how do I pick the right size?

- End mills shape and remove material to create pockets, slots, and contours.
- For aluminum, wood, and plastics, straight-shank HSS with 4 flutes yields a clean finish and good chip clearance.
- A 6mm diameter fits common 6mm collets and workpieces with 6mm pockets.
- A 57mm total length supports compact setups and shorter-depth milling.
