This 3-flute replaceable head end mill is a modular milling solution engineered for efficient slotting, keyway cutting, and cavity milling. The screw-on interchangeable head system enables fast tool changes directly on the machine spindle—eliminating the need to re-measure tool length and significantly reducing downtime. Designed for professional machinists and CNC production environments, it delivers exceptional repeatability and cost-effectiveness.
Key Features & Benefits
Quick-Change Modular System – Simply unscrew the worn head and screw on a new one. No need to remove the tool holder, reducing setup time by up to 70%.
3-Flute Optimized Geometry – Provides excellent chip evacuation and reduced cutting forces, ideal for slotting applications where chip packing could be a concern.
Premium Solid Carbide Heads – Micro-grain carbide with advanced AlTiN / TiAlN coating for superior wear resistance and extended tool life.
High Repeatability – Precision-ground taper and face contact ensure runout accuracy within ±0.0004″ (±0.01 mm) after each head change.
Versatile Application – Suitable for slotting, ramping, helical interpolation, and shoulder milling across a wide range of materials.
Applications
Keyway and slot milling in steel, alloy steel, and stainless steel
Pocket milling and cavity roughing
General-purpose milling in die & mold, automotive, and general engineering industries
Ideal for CNC machining centers, turning centers with live tooling, and automated production lines
