An endmill is a type of milling cutter that is used in milling machines to create shapes, slots, and holes in metal, wood, plastic, and other materials. An endmill has a cylindrical body and multiple cutting edges along its circumference, including a cutting end that is flat or ball-shaped and has two or more flutes. The flutes help to remove chips from the material as the endmill rotates.
Endmills are available in various sizes, shapes, and materials to suit specific milling applications and precision requirements. They are used to cut materials in a radial direction along the cutting edge, typically to a specified depth. Endmills are commonly used in manufacturing and production operations such as aerospace, automotive, and engineering.
