HSS Milling Cutter 4 Flutes End Mill Flat Router Bit High-Performance Finishing Bright Finish High-Speed Steel Square End Mills

High-performance high-speed steel end mills are designed to last longer and create a finer finish when used in their recommended, first-choice materials than general purpose end mills. They are used in production milling. Finishing end mills create a finer finish on the workpiece than roughing and roughing/finishing end mills. 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

Tips:
1. Different from ordinary high-speed steel tools, our high-performance high-speed steel tools have higher hardness, more advanced heat treatment process and higher precision;
2. Compared with common cemented carbide tools, high-performance high-speed steel tools have better toughness, lower requirements for equipment, lower requirements for workpieces and lower cost;
3. You can choose the cutting tool reasonably or consult customer service according to your own use situation requirements, workpiece requirements and cost budget.
