The D1.3×4×SD6×50-4F external cooling end mill from AMG is specifically designed for high-precision milling of stainless steel and other hard -to-machine materials. Featuring a right-hand cut and right-hand helix with a four-flute design, this micro-diameter solid carbide tool delivers excellent surface finish, dimensional accuracy, and cutting stability. It is ideal for customers seeking precision machining solutions in sectors such as medical devices, precision molds, aerospace, and electronics.

Applications

This tool is widely used for micro-feature contour milling, fine groove cutting, cavity finishing, and precision trimming on stainless steel, and hardened steels. It is compatible with multi-axis CNC machines and high-speed machining centers for automatic, high-efficiency operations.

Technical Specifications

Working Principle

The tool rotates clockwise, performing right-hand cutting with four flutes for stable chip removal. External coolant is directed precisely to the cutting edge to dissipate heat and reduce friction, preventing material work-hardening and minimizing tool wear. This ensures optimal performance in continuous or semi-continuous machining tasks requiring high surface.

Advantages

Perfect for contour milling: Micro-diameter and short flute length provide superior control in delicate profile cutting.

High wear resistance: Premium ultra-fine grain carbide offers excellent durability and thermal stability.

Excellent surface finish: Four-flute configuration ensures finer cutting passes and smoother surfaces.

Efficient cooling: External cooling design enhances heat control during stainless steel processing.

Versatile compatibility: Standard 6mm shank fits a wide range of clamping systems.

Customer Buying Guide

When selecting a tool for precision contour milling, key factors include flute count, cutting diameter, flute length, and cooling strategy. The D1.3×4×SD6×50-4F is optimized for micro-scale operations and tight-tolerance applications. It is recommended to use this end mill with high-speed spindles and high-pressure coolant delivery for best results. AMG also offers customized solutions to meet specific machining requirements.
