OSG 55° Helix Endmill Corner Radius - Centre Cutting Regular Length - 6mm x R0.3

The OSG 55° Helix Endmill is a 6 mm diameter, centre-cutting endmill with a 0.3 mm corner radius. It’s built for general machining tasks where precision and clean tool paths matter, including milling, profiling, and slotting.

With a 55-degree helix angle, it delivers efficient chip evacuation and reduced cutting forces, helping you maintain higher feed rates and smoother finishes across a range of materials. The corner radius contributes to chatter-resistant cuts and improved surface quality, making it reliable for consistent, high-quality results in everyday manufacturing and prototyping.

• 55° Helix for Efficient Chip Evacuation: The 55-degree angle helps sweep chips away quickly, reducing cutting forces and heat buildup for steadier feeds and faster cycle times.
• Corner Radius for Smoother Edges: R0.3 corners soften entry and exit paths, minimize chatter, and improve surface finish on profiles, slots, and contours.
• Centre-Cutting, Regular-Length Design: Centre-cutting geometry enables plunge cutting, while a balanced regular length delivers rigidity and versatility for a wide range of milling, profiling, and slotting tasks.

This endmill is built for reliable, repeatable results in busy shop floors. It helps you maintain tight tolerances, reduces downtime from chatter and poor finishes, and simplifies setup with predictable performance. By combining efficient chip control, smooth finishes, and versatile cutting geometry, it supports faster workflows and higher-quality parts across diverse applications.
