High-Performance 4-Flute Square End Mill
Specialized for Stainless Steel (SUS304/316). Features Unequal Indexing and Polished Flutes to eliminate chatter and prevent chip sticking.
38°/40° Variable Helix
0.4µm Ultra-Fine Micro Grain Carbide
Engineered for Excellence
Every detail is optimized for peak performance in the most demanding machining environments.
Anti-Vibration Unequal Pitch
Unequal Indexing
Asymmetric geometry disrupts harmonic vibrations (chatter), enabling heavier cuts and higher feed rates with a smooth surface finish.
High-Performance Chip Evacuation
Polished Flutes
Ultra-smooth mirror-finish flutes reduce friction, ensuring rapid chip evacuation and preventing chip packing or sticking on SUS304/316.
Ultra-Fine Micro Grain Carbide
Premium Substrate
Tungsten Carbide provides the perfect balance of hardness (HRC55-HRC65) and toughness to prevent chipping under high stress.
Advanced Coating
AlTiN / TiSiN
High heat resistance and low friction coefficient prevents Built-Up Edge (BUE) and dramatically extends tool life.
Rigid Geometry
Large Core Diameter
Ensures maximum rigidity and reduces deflection, further enhancing accuracy and stability during heavy machining.
h6 Shank Tolerance & Run-out Control
Precision Ground
Shank diameter tolerance controlled within h6, ensuring tight run-out for high-precision CNC setups.
High Performance Solid Carbide End Mill Specifications
Engineered with Variable Helix technology, specifically Designed for Stainless Steel (SUS304/316), Titanium, and high-temp superalloys.
Key Applications
High Performance Side Milling
Variable Helix geometry eliminates harmonic vibration, ensuring mirror finishes even when machining tough Stainless Steel at high speeds.
Heavy Slotting in Stainless
Specialized flute design provides superior chip evacuation, preventing work-hardening when slotting Stainless Steel (304/316).
High-Efficiency Face Milling
Large core diameter design ensures rigidity for high-feed face milling, delivering mirror finishes even on uneven surfaces.
