2 Flutes Long Neck Flat End Mill

Optimized for High-Hardness Materials up to 65HRC
Manufactured from ultra-fine grain carbide and enhanced with a high red-hardness nano-coating (e.g., HG or HH), this end mill is purpose-built for cutting hardened steels such as SKD11, H13, D2, and other tool steels. Delivers superior wear resistance and reliable edge retention in long-cycle precision machining.

2-Flute Design Ensures Superior Chip Evacuation and Reduced Cutting Force
The wide chip pockets of the 2-flute configuration allow efficient chip removal while minimizing tool load and heat generation—crucial when working in deep pockets or slots on hard materials. Ideal for finishing and semi-finishing processes where surface integrity is essential.

Long Neck Geometry for Extended Reach and Access in Deep Cavities
The extended neck design enables access to narrow and deep features while maintaining rigidity. Perfect for complex mold cores, fine ribs, and deep slots requiring precise tool control and minimal vibration.

Flat End Geometry for Accurate Shoulder Milling and Clean Bottom Finishes
The flat tip ensures high precision when creating straight walls, square corners, and flat-bottom cavities. Especially suitable for finishing dies, inserts, and fine structural details in hardened or heat-treated components.

High-Performance Coating Enables High-Speed, Dry or MQL Machining
Coated for thermal resistance and oxidation protection, the tool remains sharp and stable even at high spindle speeds under minimal or no coolant conditions. Supports sustainable machining while reducing overall production costs.

Application-Based Cutting Parameters Included – Reduce Trial-and-Error, Boost Output
Samho provides fully tested cutting data (rpm, feed rate, depth of cut) tailored to 65HRC applications. This helps users reduce setup time, improve machining consistency, and get the most out of each tool.
