CNC End Mill Comparison Guide | MatterHackers

The tip profile isn't the only thing that differentiates end mills. The spiral channels on an end mill - called flutes - determine which materials you can cut. Generally, less flutes equals better chip clearing at the expense of surface finish. More flutes gives you a nicer surface finish, but worse chip clearing.

Climb Milling versus Conventional Milling [ Sneaky CNC Tricks ]

Advantages of climb milling (Down Milling): The width of the chip starts at maximum and decreases. The cutting edge meets the workpiece at the top of the cut. Chips are dropped behind the cutter-less recutting. Less wear, with tool life being up to 50% longer. Improved surface finish because of less recutting. Less power required.
