Carbide Square Nose End Mill for Alloy Steels/Hardened Steels, 4 Flute HRC 55 Deg AlTiN Coating-Imperial
- Material : CNC 4 Flute Solid Carbide Spiral Router Bit excel at working carbon steels, alloy steels, pre-hardened steels, hardened Steels, cast iron,etc.Strictly for steel use, if milling aluminium, our 3 flute end mill is recommended.
- AlTiN Coating : Titanium aluminum nitride (AlTiN) coating lubricates the end mill for stability at high temperature and superior wear resistance at high cutting speeds, offering better heat resistance than TiAlN, TiN or TiCN coatings
- High Performance : carbide has higher hardness and wear resistance and excellent cutting performance than high-speed steel.
- Durable : HRC 55 Deg,Excellent performance in hard materials that are difficult to cut. Extremely hard, wear resistant.

PRODUCT HIGHLIGHTS
Ultra-high hardness and wear resistance: The carbide substrate provides extremely high hardness and wear resistance. With the AlTiN coating, it can maintain a sharp cutting edge under high temperature and high-speed cutting, greatly extending the tool life.
Advantages of AlTiN coating: The AlTiN coating has excellent thermal hardness and oxidation resistance, stable cutting, and reduced adhesive wear.
4-edge spiral design: The evenly distributed 4-edge spiral groove design has a more balanced cutting force distribution, reduces vibration and radial runout, and significantly improves surface finish and processing accuracy.
Multi-scenario application: It is widely used in various processing methods such as milling grooves, face milling, and intermittent cutting. It is compatible with various materials such as alloy steel, carbon steel, and cast iron to meet the processing needs of complex parts.

APPLICATION SCENARIOS
Mold manufacturing: Efficiently remove hard cavity materials to ensure mold cavity accuracy and surface quality. High temperature and wear resistance, significantly extending the service life.
Mechanical mass production: Maintain stability under high cutting loads, suitable for large-scale and continuous production, and reduce the frequency of tool changes.
