2 Flutes Long Neck Corner Radius End Mill

Specialized for Hardened & Heat-Treated Steels up to 65HRC
Made from ultra-fine grain carbide and protected by a high red-hardness nano-coating (such as HH), this tool delivers excellent wear resistance and oxidation stability. It’s engineered for machining materials like SKD11, H13, and D2 with consistent precision and tool life.

2-Flute Geometry for Efficient Chip Evacuation and Stable Cutting in Deep Features
The wide flute spacing allows smooth chip removal and minimizes cutting resistance, which is essential when milling narrow slots, deep cavities, and fine ribs in hardened workpieces. The 2-flute structure reduces heat buildup and ensures cleaner finishes.

Long Neck Design Ensures Deep Reach Without Compromising Rigidity
The extended neck length provides access to intricate internal features while maintaining core strength and anti-vibration performance. Ideal for mold cavities, dies, and narrow-wall components that require accurate tool access and minimal deflection.

Corner Radius Tip Increases Edge Strength and Surface Integrity
The corner radius helps distribute cutting forces more evenly and prevents edge chipping—extending tool life and improving surface finish consistency, especially in contour milling or when handling interrupted cuts in hardened steels.

Supports High-Speed Machining in Dry or MQL Conditions
Coated with a high-performance heat-resistant layer, the tool maintains hardness and sharpness at elevated temperatures. This makes it suitable for high-speed machining under dry or minimum lubrication environments, improving productivity and environmental compatibility.

Application-Specific Cutting Parameters Provided for Hardened Steel
Samho offers comprehensive cutting data tailored to 65HRC-level materials, including spindle speed, feed rate, and cutting depth. This shortens setup time, improves process stability, and maximizes tool utilization with less trial-and-error.
