Description
The OSG Carbide 4 Flute End Mill with a corner radius and TiSlN coating is a precision cutting tool engineered for exotic materials. Its 4-flute design delivers efficient material removal with stable cutting, making it ideal for challenging alloys and composites.
With a 3 mm diameter and a 0.5 mm corner radius, this end mill combines edge strength and wear resistance to withstand demanding operations while delivering consistent finishes. The TiSlN coating enhances durability, helping you push harder materials with confidence every day.
- Four-flute efficiency and stability: The 4-flute geometry provides balanced material removal with improved rigidity, reducing chatter and enabling cleaner cuts and faster cycles.
- R0.5 corner radius for reliable corners: The precise corner radius protects delicate features during contouring, minimizes edge chipping, and supports consistent surface quality on complex profiles.
- TiSlN coating for extended tool life: The TiSlN coating boosts wear resistance and heat tolerance, allowing higher cutting speeds and longer intervals between tool changes when working with exotic materials.
This end mill helps you maintain tight tolerances and smooth finishes while boosting productivity in tough materials. Its robust geometry, protective coating, and compact 3 mm form factor make it a dependable choice for professionals and hobbyists who demand reliable performance, reduced downtime, and consistent results across challenging machining tasks.
