 6 Core Upgrades  
1. Nano Coating  
2. Fine Micro-Grain Structure  
3. High Wear Resistance  
4. Smooth Cutting Performance  
5. Solid Tungsten Carbide Construction  
6. Clean and Smooth Cutting Surface  

【Stringent Material Selection】
0.2UM micro-grain tungsten carbide hard alloy
We use raw tungsten carbide from leading manufacturers—no recycled materials. The tool is integrally formed in one piece, precision-ground with high-end ANCA grinding equipment and high power, ensuring exceptional stability and fundamentally guaranteeing tool quality. The micro-grain tungsten carbide substrate offers higher wear resistance and strength, excellent processing performance, and maintains high hardness even under high temperatures generated during high-speed cutting.

【TiSiN Nano Coating】  
- Multi-layer coating technology enhances processing efficiency  
- TiSiN coating provides high hardness, excellent wear resistance, high thermal conductivity, smooth surface finish, and corrosion resistance  
- Ensures stable performance and extended tool life.

【Cutter Head Design】
1. A suitable negative rake angle is adopted to balance edge strength and sharpness. Combined with a large core diameter, the tool's rigidity is enhanced, ensuring stable cutting and chip evacuation.  
2. The 30-degree helix angle design, dual blade bands, and a versatile edge groove design make it suitable for both roughing and finishing. The large chip flute prevents chip adhesion, significantly extending tool life.  
3. The dual arc + 30-degree helix angle design enhances the milling cutter's wear resistance, reduces burrs during processing, and delivers high surface finish quality. 
【Tool Shank Design】  
- Universal chamfered round shank ensures firm grip and easy clamping  
- Durable and user-friendly
【Applicable materials】Cast iron, steel, copper alloys, aluminum, carbon steel, and other metals.
【Compatible Machines】
CNC machining centers, precision drilling machines, and stable conventional drilling machines.


【Application Scenarios】
 1. Side milling  
2. Surface machining  
3. Countersinking  
4. Side processing  
5. Groove cutting

【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%.
