What is 3 Flute End Mill?
The 3 flute end mill is a precision cutting tool engineered for high-speed aluminum machining. Its three spiral flutes balance cutting force and chip evacuation – delivering 30% faster chip removal than 2-flute tools while outperforming 4-flute versions in rigidity. Ideal for milling, slotting, and contouring aluminum, stainless steel, and alloy steels, it achieves superior surface finishes in CNC operations.
Key Features：
1. Optimized Chip Evacuation
Enlarged chip pockets prevent chip welding in aluminum, reducing surface defects by 60% during high-speed machining.
2. Extreme Durability
- Submicron carbide core: 40% higher impact resistance
- AlTiN/TiSiN coating: Withstands 1100°C heat
- 200% longer lifespan vs standard end mills
3. Material-Specific Edges
- Sharp edge: For aluminum, copper
- Chamfered edge: For hardened steels (HRC45+)
- Adjustable helix angles (30°-50°): Optimize cutting force
4. Vibration-Free Machining
Variable helix design eliminates chatter, enabling precision milling of thin walls and aerospace components.
5. Multi-Material Versatility
Single-tool solution for aluminum, titanium, stainless steel, supporting dry/wet machining.

Our company specializes in manufacturing and customizing a wide array of cutting tools, dedicated to boosting clients' production efficiency and slashing manufacturing costs. We offer comprehensive tool solutions tailored for various cutting materials, encompassing carbon steel (approx. HB225 hardness), alloy steel (HB225~325 hardness), pre-hardened steel (up to HRC45 hardness), quenched steel (HRC40~61 hardness), and cast iron. These solutions cater to diverse cutting needs, including straight cuts, curved cuts, L-shaped cuts, groove cuts, internal arc cuts, external arc cuts, T-shaped cuts, drilling, and threading.
Our carbide cutting tools excel in processing the aforementioned steel types, delivering exceptional performance with a precision tolerance of just ±0.02mm. This ensures that our customers can effortlessly achieve professional-grade cutting quality, making us your ideal partner for milling tool solutions.
We can provide customized OEM production services. If our standard carbide milling cutters do not meet your requirements, you can customize the diameter within 0.2mm-25mm, the total length from 50mm to 200mm, and choose flutes of 4F, 5F, 6F, or 8F. You can also add your own logo. Please feel free to contact us for any needs.
