Product Details

The bright finish on these end mills provides a smooth, polished surface. Finishing end mills create a finer finish on the workpiece than roughing and roughing/finishing end mills. Miniature end mills have a smaller diameter and provide more precision and better control over material removal during detailed milling tasks than standard end mills.

Miniature high-speed steel 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. General purpose end mills are intended for milling a wide variety of common materials but are not suitable for milling hard materials like titanium or gummy materials like aluminum. High-speed steel end mills offer good wear resistance for basic milling applications. They're more flexible and can absorb more shock and vibration than carbide, cobalt, or powdered-metal end mills. Sometimes called square-nose end mills, square end mills have a square nose and are rotated against a piece of stock to create a flat-bottomed groove with 90° inside corners in milling tasks. They are used for counterboring, side and face milling, and milling square shoulders.
