Description

The OSG Carbide 4-Flute End Mill is a long-length, 16 mm diameter carbide cutter featuring a square-edge profile and a TiSlN coating. Designed specifically for exotic materials, it delivers stable cutting, precise geometry, and reliable performance in challenging workpieces.

This tool is ideal for professionals and technically minded hobbyists alike who need extended reach without sacrificing accuracy. Its square-edge design helps produce clean pockets and sharp corners, while the TiSlN coating helps resist wear and heat during demanding milling operations.

  • Long-reach, square-edge design: Extended reach enables access to deep pockets, slots, and through-holes, while the square edge ensures precise, true-cut corners for consistent results.
  • Four-flute balance for efficiency: Four flutes provide solid material removal with good rigidity, delivering steady cutting performance and a smoother finish on tough materials.
  • TiSlN coating for durability: The TiSlN coating boosts wear and heat resistance, extending tool life and reducing downtime in demanding exotic-material applications.

By choosing this end mill, you benefit from dependable, high-precision milling that preserves edge life and reduces tool changes, helping you complete challenging jobs faster with consistent, high-quality results.
