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】  
- Made with 0.2μm micro-grain tungsten carbide hard alloy  
- We use raw materials from leading suppliers—no recycled materials  
- One-piece solid tungsten carbide construction for stability  
- Precision grinding with high-power equipment ensures consistent accuracy  
- The micro-grain tungsten carbide base offers higher wear resistance and strength, maintaining 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】  
- Available in 60°/90°/120° chamfer angles for precise milling  
- Three-flute straight groove design enhances wear resistance, reduces burrs, and minimizes chip adhesion  
- Improves chip evacuation efficiency and offers strong anti-vibration performance  
- Enhanced tool rigidity reduces chipping and frequency of tool changes, extending tool life

【Tool Shank Design】  
- Universal chamfered round shank ensures firm grip and easy clamping  
- Durable and user-friendly

【Applications】  
- Suitable for chamfering round holes and beveled edges (not suitable for spot drilling)

【Compatible Materials】  
- Can process metals such as cast iron, steel, copper alloys, aluminum, carbon steel, stainless steel, etc.

【Compatible Machines】  
- CNC machines, engraving machines, precision engravers  
- Not suitable for bench drills or hand drills

【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%.
