Product Overview

Our 4-Flute Carbide Step End Mill is a premium cutting tool engineered for high-performance machining in the toughest materials. Featuring advanced through-coolant technology and a durable AlTiN coating, this end mill delivers exceptional heat resistance, extended tool life, and superior chip evacuation—making it ideal for deep cavity milling, slotting, and profiling in aerospace, mold & die, and heavy industrial applications.

Key Features
  • Solid Tungsten Carbide Construction - Ultra-hard (92-94 HRA) for maximum wear resistance in hardened steels (up to HRC 60) and exotic alloys.
  • 4-Flute Optimized Design - Balances material removal rate and surface finish, reducing vibration during high-speed operations.
  • Through-Coolant Channels - Internal coolant holes (Ø1.5mm or custom) deliver precise lubrication to the cutting edge, minimizing heat buildup and prolonging tool life.
  • AlTiN (Aluminum Titanium Nitride) Coating - Enhances hardness (3,800 HV) and thermal stability (up to 900°C), ideal for dry or near-dry machining.
  • Step-End Geometry - Combines roughing and finishing in one tool, eliminating the need for multiple tool changes.
  • High-Speed Capable - Engineered for 10,000+ RPM CNC machining centers.
Performance Advantages
  • 50% Longer Tool Life: AlTiN coating reduces flank wear in abrasive materials like titanium and Inconel.
  • Efficient Heat Dissipation: Through-coolant design prevents thermal cracking in deep-pocket milling.
  • Versatile Performance: Single tool handles slotting, side milling, and plunging operations.
  • Reduced Downtime: Fewer tool changes increase productivity in batch processing.
Typical Applications

Aerospace: Machining turbine blades (Ti-6Al-4V), engine mounts.

Mold & Die: Deep cavity milling in hardened tool steels (P20, H13).

Oil & Gas: Valve components (Inconel 718, 17-4PH stainless).

Medical: Implant machining (cobalt-chrome, stainless steel).
