OSG Carbide 4 Flute End Mill Square Edge TiSlN Coated - For Exotic Materials - 20mm

The OSG Carbide 4 Flute End Mill features a square-edge design and a TiSlN coating, tailored for machining exotic materials. With a 20 mm diameter and four cutting edges, it delivers efficient material removal while preserving accuracy and stability in demanding applications.

This end mill is ideal for machinists, engineers, and hobbyists who regularly tackle tough or exotic alloys. Its coating and geometry are chosen to withstand high heat and abrasion, providing reliable performance across pockets, slots, and contouring operations where precision matters most.

• Four-flute design for fast, stable material removal: Four cutting edges deliver efficient chip evacuation and strong cutting action, helping you achieve consistent pocketing, slotting, and contouring in exotic materials with fewer passes and less chatter.
• TiSlN coating for extended tool life: The Titanium Silicon Nitride coating reduces wear and friction, boosting wear resistance and enabling reliable performance in hard-to-machine alloys and other exotic materials.
• Square-edge geometry for precise, clean finishes: The square end produces true 90-degree cuts for accurate pocket walls and crisp end surfaces, delivering tight tolerances and a smooth surface finish.

With this end mill, you can expect dependable, repeatable results even in challenging materials. The combination of carbide hardness, TiSlN coating, and precise geometry helps reduce downtime, minimizes tool changes, and improves throughput, so you can finish projects faster while maintaining quality and consistency across runs.
