Miniature square end mills have a smaller diameter than standard square end mills, which allows them to provide more precision and better control over material removal during milling tasks. They are suitable for detailed milling applications such as dental milling or small-electronics manufacturing. Square end mills have a square nose and are rotated against a piece of stock to create flat-bottomed grooves with 90° inside corners. They are used for counterboring, side and face milling, and milling square shoulders.
