Description
The OSG Carbide 4 Flute End Mill is a center-cutting, 8 mm diameter tool with a 0.5 mm corner radius, TiAlN coating, and four-flute geometry.

- Center-Cutting Versatility: Center-cutting geometry enables plunging and versatile milling, allowing quick slotting and profiling in a single setup.
- Corner Radius for Smooth Edges: The R0.5 corner radius produces smoother profiles and better edge quality, reducing chipping and improving surface finish on varying depths.
- TiAlN-Coated Four-Flute Durability: Four-flute geometry paired with TiAlN coating delivers efficient material removal, enhanced heat resistance, and extended tool life for demanding applications.
This end mill is designed to keep your workflow moving—delivering consistent tolerances, reliable finishes, and longer tool life across a range of materials. With its robust carbide construction and protective TiAlN coating, you can tackle everyday machining tasks with confidence, reducing downtime and rework while achieving clean, professional results.
