Description
The OSG Carbide High Helix End Mill Square Edge with TiAlN coating is a general‑purpose cutting tool engineered for a wide range of machining tasks. With a regular length flute and a 6 mm diameter, it delivers dependable performance for milling, slotting, and profiling across various materials. The high‑helix design promotes fast chip evacuation and helps keep cutting forces manageable, supporting steadier feeds and cleaner finishes.
- TiAlN coating for longer tool life: The advanced coating boosts wear resistance and heat tolerance, helping the tool stand up to demanding materials and extended cutting runs so you replace tooling less often.
- High‑helix geometry for efficient chip evacuation: Aggressive chip removal reduces heat buildup and clogging, enabling smoother cuts and consistent results even in challenging workpieces.
- 6 mm diameter with corner radius R for versatile precision: The combination of size and rounded edge provides strong cutting edges and improved control for slots, contours, and profiling with durable edge quality.
This end mill is designed to deliver reliable, repeatable results across aerospace, automotive, and general manufacturing applications. By combining durable TiAlN coating, efficient chip handling, and a robust corner‑radius edge, it supports faster cycle times, better surface finishes, and lower downtime—helping you achieve precise parts and maintain productive workflows from start to finish.
