Premium 4-Flute Step End Mill for Precision Die/Mold Manufacturing

Our 4-Flute Step End Mill is engineered for demanding die/mold manufacturing and precision machining applications. Designed specifically for hardened mold steels (P20, H13, D2) and alloy steels, this solid carbide end mill combines high-accuracy step geometry with optimized flute design to deliver exceptional surface finish and extended tool life in complex milling operations.

Key Features

4-Flute High-Efficiency Design: Balanced between material removal rate and surface finish quality with helical flute geometry that reduces vibration during side milling
Premium Micro-Grain Tungsten Carbide: Sub-μm grain structure (0.6-0.8μm) for machining materials up to HRC 55 with higher transverse rupture strength
Step Geometry Advantages: Multiple cutting diameters in one tool (e.g., 6mm-12mm in 2mm steps) with 30°/45°/90° shoulder angles available
Specialized Coating Options: AlTiN coating (standard) for high-temperature resistance, TiSiN (optional) for abrasive composites, and polished flutes (optional) for non-ferrous materials
Coolant Through Capability: 2-4 internal coolant holes (Ø1.2mm standard) maintains consistent cutting temperature in deep cavities

Performance Advantages

• 40% faster machining vs conventional end mills in S7 tool steel

• Ra 0.4 μm surface finish achievable in finishing passes

• Tool life 3X longer than HSS-E mills in hardened D2 steel

• Single tool operation replaces multiple tools for roughing & finishing

Recommended Applications

Mold Manufacturing: Core/cavity machining in P20 (HRC 30-36), ejector pin holes in H13 (HRC 48-52)

Precision Die Making: Progressive dies in D2 tool steel, blanking punches in A2 steel

Industrial Components: Turbine blade roots in 17-4PH stainless, hydraulic valve bodies in 4140 pre-hard
