YOUCUT 4 Flute Corner Radius Carbide End Mill

Model: D6-15-D6-50L-4T
Applications: High-efficiency roughing, semi-finishing, and complex contour machining of steel (4140, H13), stainless steel (304, 17-4PH), titanium (Ti6Al4V), Inconel, and hardened materials (HRC 60+).

 

Key Features

 Corner Radius Advantage

• R0.4-R2.0mm Edge Radius: Strengthens cutting edges, reduces chipping, and extends tool life by 30% vs. sharp-corner end mills.

• Smooth Transition Finishing: Eliminates stair-stepping artifacts in 3D contours (Ra ≤0.4μm).

 Extreme Durability

• TiAlN Hyper-Coating: Withstands temperatures up to 900°C, ideal for dry machining hardened steels.

• Micro-Grain Carbide Substrate: Optimized for high feed rates (0.15-0.3mm/tooth) in tough alloys.

 Advanced Geometry

• 4-Flute Helical Design: Balanced radial forces for vibration-free 5-axis machining.

• Variable Pitch & Helix: Minimizes harmonics in high-RPM operations (up to 20,000 RPM).

 

Technical Specifications

• Diameter Range: 3mm-25mm (Standard), Custom up to 40mm

• Corner Radius: R0.4mm / R0.8mm / R1.2mm / R2.0mm

• Flute Length: 4×D / 6×D (Deep cavity optimized)

• 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: 20,000 (Refer to material-specific speed/feed charts)

 

Performance Benefits

 High Material Removal Rate (MRR): Aggressive roughing with 20% higher feed rates vs. standard end mills.
 Chip Thinning Control: Optimized geometry prevents chip overload in deep slots.
 Multi-Tasking Ready: Single tool for roughing, semi-finishing, and finishing.

 

Ideal Use Cases

• Aerospace: 3D profiling of titanium engine mounts and Inconel turbine disks.

• Automotive: High-feed machining of hardened steel stamping dies (HRC 60+).

• Medical: Precision milling of surgical tool stainless steel components.

• Mold & Die: Complex cavity machining in P20 and H13 tool steels.

• Energy: Slotting heat-resistant alloys for nuclear reactor components.

 

Safety & Maintenance

Use High-Precision Hydraulic Chucks to minimize tool runout (<0.003mm).
Avoid interrupted cuts in titanium: Use trochoidal milling strategies.
Clean with alkaline solvents; store coated tools in anti-tarnish packaging.

 

Packaging & Support

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

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

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

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