End Mills

An end mill is a versatile rotary cutting tool with blades (flutes) on its sides and bottom, used in milling machines (including CNC) to remove material, create complex shapes, and machine pockets, slots, and contours in metals, plastics, wood, and composites, unlike drill bits that only cut downward. They come in various materials (HSS, carbide) and designs (square, ball nose, tapered)
