Premium Performance Cutting Tool

Our 4-Flute Carbide Step End Mill is engineered for high-performance machining in tough materials. Featuring advanced through-coolant technology and durable AlTiN coating, this end mill delivers exceptional heat resistance, extended tool life, and superior chip evacuation - ideal for deep cavity milling, slotting, and profiling in demanding 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 while reducing vibration
Through-Coolant Channels - Internal coolant holes (Ø1.5mm or custom) provide precise lubrication to cutting edges
AlTiN Coating - Enhances hardness (3,800 HV) and thermal stability (up to 900°C)
Step-End Geometry - Combines roughing and finishing in one tool
High-Speed Capable - Engineered for 10,000+ RPM CNC machining centers
