- fewer flutes have more chip-carrying capacity and more flutes produce a finer finish.
- Cobalt steel resists abrasion and high cutting temperatures, and has higher feed rates than high-speed steel.
- Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials.
- Square nose end mills (also called square end) create sharp, unrounded cuts.
- Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling.
