YOUCUT 4 Flutes Carbide Flat End Mill

Model: D4-10-D4-50L-4T
Applications: High-efficiency slotting, contouring, and finishing of steel (P20, 4140), stainless steel (304, 316), titanium alloys, aluminum, and hardened materials (HRC 55+).

 

Key Features

 Multi-Material Mastery

• 4-Flute Helical Design: Balanced cutting forces for vibration-free machining across steels, stainless, and non-ferrous metals.

• Flat Bottom Geometry: Sharp 90° edges for precise flat surfaces and clean slotting (Ra ≤0.4μm finish).

 Extended Tool Life

• TiAlN Nano-Coating: Withstands temperatures up to 900°C, reducing flank wear in hardened steels.

• Micro-Grain Carbide Substrate: 4x lifespan vs. HSS end mills in high-speed applications.

 Advanced Cooling & Stability

• Coolant Through Channels (Optional): Directs high-pressure coolant to cutting edges for heat-sensitive alloys like Inconel.

• Reinforced Shank Design: Minimizes deflection in deep cavities (up to 5×D cutting depth).

 

Technical Specifications

• Diameter Range: 3mm-20mm (Standard), Custom up to 30mm

• Flute Length: 4×D / 6×D (Optimized for stability)

• Shank Diameter: 6mm-16mm (1/4"-5/8")

• Coating Options: TiAlN (Gold) / AlCrN (Black) / Uncoated (For Non-Ferrous)

• Tolerance: ±0.005mm (Precision ground to aerospace standards)

• Max RPM: 24,000 (Refer to material-specific speed/feed charts)

 

Performance Benefits

 High Material Removal Rate (MRR): Aggressive roughing and fine finishing in one tool.
 Chip Control: Optimized chip breaker design prevents chip jamming in deep slots.
 Multi-Axis Compatibility: Stable in 5-axis CNC machines for complex geometries.

 

Ideal Use Cases

• Aerospace: Profiling titanium turbine blades and stainless steel brackets.

• Automotive: Machining hardened steel molds for injection molding.

• Medical: High-precision milling of surgical instrument components.

• Energy: Slotting Inconel 718 parts for gas turbines.

• General Engineering: Batch production of aluminum fixtures and jigs.

 

Safety & Maintenance

Use High-Precision Tool Holders (e.g., hydraulic chucks) to minimize runout.
Avoid excessive feed rates: Use chip load calculators for optimal parameters.
Clean with alkaline solvents; store in anti-rust sleeves for coated tools.

 

Packaging & Support

• Professional Kit: Individually sealed in nitrogen-filled anti-tarnish packaging.

• Bulk Orders: 10 pcs/box with shockproof foam.

• Warranty: 12-month quality guarantee (Excludes abrasive material misuse).

• Free Resources: Speed/Feed Calculator + CAM Toolpath Optimization Guide.
