Description
The OSG Carbide 4 Flute End Mill with a corner radius and TiSlN coating is designed for machinists who routinely work with exotic materials. Sized at 16 mm in diameter with a 3 mm corner radius (R3), this precision end mill delivers stable cutting, clean pockets, and dependable performance across demanding jobs. Its four-flute geometry helps balance rapid material removal with precision, making it a reliable choice for contouring, pocketing, and finishing operations.
- Corner Radius for Smooth, Precise Contours: The R3 corner radius lets you define sharp, accurate edges while reducing chipping and creating uniform radii in pockets and profiles.
- TiSlN Coating for Durability and Wear Resistance: The advanced coating enhances heat resistance and reduces wear, helping the tool last longer in hard-to-machine exotic materials.
- Four-Flute Carbide Design for Powerful Material Removal: The four flutes provide efficient chip evacuation and stable cutting, improving finish quality and reducing downtime in demanding applications.
With this end mill, you gain consistent, repeatable results, less downtime from tool wear, and a straightforward setup that fits into existing workflows. Its durable construction and coated surface help you maintain tight tolerances on challenging materials, finish profiles cleanly, and complete parts faster without sacrificing accuracy or finish quality.
