Product Description

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
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
