Description
The OSG Carbide 4 Flute End Mill is a 5 mm diameter, regular-length, center-cutting tool with a 0.25 mm corner radius. TiAlN coated and optimized for general machining, it delivers reliable performance for milling, slotting, and profiling across a broad range of materials.
Designed for versatility, this end mill combines a four-flute geometry with a durable TiAlN coating to handle tougher materials and maintain sharpness at higher cutting speeds. The corner radius enhances tool life and provides smoother cuts, helping you achieve consistent surface finishes with fewer passes.
- Efficient 4-flute geometry: Higher chip removal and stable cuts enable faster milling, slotting, and profiling with consistent results across common materials.
- Corner radius for smoother cuts: The R0.25 corner radius reduces edge chipping and delivers cleaner profiles, improving surface finish on corners and contours.
- TiAlN coating for durability: Enhanced wear and heat resistance extend tool life in demanding applications, supporting reliable performance at higher speeds.
In practice, this end mill provides a dependable, versatile cutting solution that supports efficient material removal, consistent tolerances, and clean finishes in everyday general machining tasks. Its robust build and coating help you achieve repeatable results, minimize tool changes, and keep production moving smoothly.
