【Stringent Material Selection】 
0.2µm Micro-Grain Tungsten Carbide Hard Alloy  
We use premium virgin tungsten carbide from leading suppliers—no recycled materials. The solid carbide is formed in one piece and precision-ground with high-power equipment to ensure stable accuracy and fundamental tool quality. The micro-grain substrate provides higher wear resistance, strength, and excellent performance under high-speed cutting, maintaining hardness even under extreme heat.

【TiAlN+TiSiN Nano Coating】  
TiAlN+TiSiN is a high-end coating primarily used in severe machining environments. When your machining tasks involve hard materials, high temperatures, high wear, or material adhesion issues, TiAlN+TiSiN coating is often an excellent choice worth considering, thanks to the following properties:

1. Super-Hardness and Wear Resistance: Its hardness can easily exceed 40 GPa, making it highly suitable for machining hard materials (such as hardened steel, high-temperature alloys) and applications with significant abrasive wear.
2. Excellent High-Temperature Performance:It inherits the oxidation resistance of TiAlN, leading to slow performance degradation and long service life during continuous high-temperature cutting.
3. Good Toughness:The nano-multilayer structure effectively inhibits crack propagation, making the coating impact-resistant and suitable for intermittent cutting or milling operations.
4. Low Friction Coefficient and Anti-Adhesion Properties: It effectively reduces friction and adhesion with workpiece materials, making it particularly suitable for machining sticky materials (such as stainless steel, aluminum alloys, titanium alloys), improving chip evacuation and surface finish.
5. Smooth and Dense Surface: The coating surface is typically smoother, which helps reduce cutting forces and cutting temperatures.
【Cutter Head Design】  
- Negative Rake Angle: Optimized for edge strength and sharpness.  
- Large Core Diameter: Enhances tool rigidity for stable cutting and chip evacuation.  
- 35° Helix Angle & Dual Land Design: Improves surface finish and wear resistance.
- Versatile Flute Geometry: Suitable for both roughing and finishing.  
- Large Flute Volume: Prevents chip adhesion and significantly extends tool life.

【Instructions for Use】
Information buyers need to know when selecting and operating the tool:
1. Before using the tool, check the tool runout. If the runout accuracy exceeds 0.01mm, correct it before proceeding with cutting.  
2. Keep the tool extension out of the collet as short as possible. If a longer extension is necessary, reduce the speed, feed rate, or depth of cut.  
3. If abnormal vibration or noise occurs during cutting, reduce the speed and feed rate until the situation improves.  
4. For cooling steel, mist or air spray cooling is recommended, as it significantly enhances the milling tool’s performance.  
5. Cutting performance can be affected by the workpiece, machine, and software. The provided data are for reference only. Once the cutting process stabilizes, the feed rate can be increased by 30% to 50%.
