Product Overview

This product is a high-performance, solid carbide Deep hook flat End mill commonly known as a micro-diameter long-neck end mill). It is specifically engineered for high-aspect-ratio features such as deep cavities, narrow slots, and high vertical shoulders in precision mold-making and micro-machining. The combination of a miniature cutting diameter and an extended clearance neck allows it to perform high-precision milling where standard end mills cannot reach.

Key Features & Advantages

Micro-Diameter & Long-Neck Geometry: Featuring an extremely small cutting diameter paired with an extended, reduced-diameter neck. This layout allows the tool to safely submerge into deep pockets, narrow channels, or alongside high walls for peripheral and bottom finishing without the risk of shank collision.

Anti-Vibration & High-Rigidity Design: To counteract the deflection ("tool push") and chatter common to long-reach tools, it utilizes an optimized neck taper connection and core thickness. Coupled with a premium micrograin tungsten steel substrate, it delivers superior bending resistance.

Advanced Nano-Composite Coating: Finished with a premium bronze/copper-colored thermal-barrier coating (such as TiAlN, AlTiN, or advanced nano-structured coatings). It provides exceptional red-hardness and oxidation resistance, ensuring outstanding wear resistance during high-speed, dry-cutting operations.

Precision-Ground Multi-Flute Head (As shown in the close-up): The cutting edges and end flutes are meticulously ground to ensure extreme sharpness and zero burrs. The optimized helical flute geometry facilitates rapid evacuation of microscopic chips, guaranteeing an ultra-smooth surface finish and strict dimensional tolerances.
