An extended end mill is a specialized cutting tool primarily used in machining and milling operations. It belongs to the category of rotary cutting tools and is designed to remove material from a workpiece by advancing it into a rotating cutter. The term "long" refers to the extended length of the tool, which enables it to reach deep recesses or pockets in a workpiece that shorter end mills cannot access.
Long-end mills are typically made from high-speed steel (HSS) or carbide materials and feature a cylindrical body with cutting edges on either end. The cutting edges can vary in geometry, including square, ball-nose, corner-radius, or tapered designs, each suited to specific machining tasks and materials.
Long-end mills are commonly used in milling operations such as slotting, profiling, contouring, and plunging. They offer advantages when deep or hard-to-reach features must be machined precisely and efficiently. The extended length of the tool provides better access and visibility, allowing operators to achieve intricate shapes and contours while maintaining dimensional accuracy.
In CNC machining environments, long-end mills are essential for requiring deep cavities, moulds, or intricate designs in materials like metal, wood, plastic, and composites. They are also utilized in manual milling machines for various industrial and manufacturing applications, including aerospace, automotive, mould-making, and tool and die production.
Overall, the long-end mill represents a versatile and indispensable tool in the arsenal of machinists and fabricators, enabling them to accomplish complex machining tasks with accuracy and efficiency.
