5 Flutes 12mm Carbide Square End Mill CNC Milling Cutter For Finish Milling

Introduction:

AMG's premium 5-flute 12mm square end mill delivers exceptional surface quality and dimensional accuracy in finishing operations. Designed specifically for high-efficiency semi-finishing to final finishing, this cutter achieves Ra 0.1-0.2μm surface finishes while maintaining tight tolerances (±0.005mm).

Features:

✔ High-Density Cutting Edges

• 5-flute design maximizes feed rate potential

• 40° helix angle for smooth cutting action

• Perfect balance between MRR and finish quality

✔ Premium Carbide Substrate

• Nano-grade 0.3μm grain tungsten carbide

• Extra-high rigidity core design

• Optimized for hardened steels (up to HRC 55)

✔ Advanced Coating Technology

• Standard: AMG HyperCoat (AlTiSiN)

• Alternative: Diamond coating for non-ferrous

• Extreme: Nano-composite for high-temp alloys

Performance Advantages:

For Precision Finishing:

• 50% higher feed rates than 4-flute end mills

• Eliminates polishing in most applications

• Exceptional corner stability in profiling

For Process Optimization:
