HRC 60° Hardness Colorful Nano-Coated U-Shaped Flute Carbide End Mill for High-Speed Aluminum Milling

Product Overview

The HRC 60° Colorful U-Chip End Mill is a premium cutting tool engineered specifically for high-efficiency machining of non-ferrous metals, particularly aluminum and copper alloys. Featuring a stunning, high-performance colorful nano-coating, this tool combines striking aesthetics with exceptional wear resistance and anti-sticking properties. Its signature wide U-shaped flute geometry ensures seamless chip evacuation, successfully tackling the challenges of chip packing and built-up edge (BUE) in high-speed operations.

Key Features & Technical Advantages

High Hardness Substrate (HRC 60°): Crafted from premium micro-grain tungsten carbide, achieving a core hardness of HRC 60°. This balance of high hardness and excellent toughness prevents chipping during high-speed and heavy-load machining.

Colorful Nano-Coating: The innovative rainbow/colorful composite coating provides an ultra-low friction coefficient (approx. 0.2–0.3) and superior thermal stability. It drastically reduces cutting heat and resistance, eliminating the tendency of soft metals like aluminum and copper to weld to the cutting edge.

Optimized U-Chip Flute Geometry: Specifically designed with wide, deep U-shaped flutes to accommodate the long, continuous chips characteristic of aluminum and copper. This enables rapid chip clearance, prevents tool breakage due to chip clogging, and ensures excellent surface finishes.

Sharp & Balanced Cutting Edge: Engineered with a high rake angle and optimized relief angle for effortless, smooth cutting action. It significantly minimizes vibration, enabling mirror-like surface finishes on the workpiece.

Applications

Target Materials: Aluminum alloys (e.g., 6061, 7075), pure copper, brass, bronze, magnesium alloys, plastics, and light machining of stainless steel.

Compatible Machines: CNC machining centers, CNC milling machines, and high-speed engraving machines.

Operaions: Slotting, side milling, shoulder milling, roughing, and finishing.
