Deep Hook Ball Nose End Mill: small-diameter, long-reach coated solid carbide ball nose end mill (commonly known as a micro-diameter long-neck ball end mill). It is specifically engineered for high-precision 3D profile milling, semi-finishing, and finishing of complex curved surfaces in miniature molds and dies. The combination of a miniature ball nose radius and an extended clearance neck allows it to navigate deep, narrow dimensional contours and pocket corners where standard tools would interfere.
Micro Ball Nose & Long-Neck Geometry: Features a miniature spherical cutting tip paired with an extended, reduced-diameter neck. This allows the tool to plunge safely into deep, narrow cavities or along steep walls for multi-axis 3D surface machining without shank rub or tool-workpiece collision.
High-Precision Ball Radius (As shown in the close-up): The spherical cutting edge is meticulously ground to maintain extremely tight contour tolerances (R-angle tolerance). The S-shaped center gash design ensures smooth continuous cutting and excellent chip formation, delivering a mirror-like surface finish.
Advanced Nano-Composite Coating: Finished with a premium bronze/copper-colored thermal-barrier coating (such as TiAlN, AlTiN, or advanced nano-structured coatings). It offers excellent red-hardness, a low friction coefficient, and high oxidation resistance, significantly reducing tip wear during high-speed, dry-milling operations.
Anti-Vibration & High-Rigidity Design: To address the common challenges of tool deflection and breakage inherent in micro long-neck tools, it features an optimized neck taper and core web design. Built on an ultra-fine grain solid carbide substrate, it ensures maximum core strength and stability.
Machining Operations: 3D profile finishing of complex mold cavities, corner-clearing and rest-milling in deep pockets, radius-bottom slotting, and micro-machining/deburing for medical and electronic hardware.
Applicable Materials: Thanks to its advanced substrate and coating combination, it is highly optimized for:
Mold Steels and Pre-Hardened Steels (Capable of machining up to HRC 55-65)
Carbon Steels, Alloy Steels, and Stainless Steel
Various high-precision components and difficult-to-machine heat-resistant alloys.
