Description

The OSG Carbide High Helix End Mill is a versatile square-edge cutter designed for general machining, featuring an 8 mm diameter, corner-radius geometry (R), a regular-length body, and a TiAlN coating. Its high-helix flutes promote fast chip evacuation and reduced cutting forces, making it ideal for milling, slotting, and profiling across aerospace, automotive, and general manufacturing tasks.

  • High-helix geometry for efficient chip evacuation: The elevated flute angle minimizes cutting resistance and clears chips quickly, helping you achieve smooth finishes and higher feed rates across a variety of materials.
  • TiAlN coating for extended tool life: The hardened titanium aluminum nitride coating reduces wear and heat buildup, delivering longer cutting life and more consistent performance in demanding operations.
  • Corner-radius design for durability and precision: The corner-radius geometry strengthens edges at corners, reduces chipping, and enables cleaner pockets and contours for reliable, repeatable results.

By choosing this end mill, you gain a dependable, adaptable tool that supports precise results, reduces downtime through longer life, and helps producers maintain clean finishes across a range of general machining tasks.
