65 Mold Steel Long Neck Corner Radius End Mill【2 Flutes Φ0.2-2】

Purpose-Built for Hardened Steels up to 65HRC – Combines Reach, Strength, and Surface Quality
Crafted from ultra-fine grain carbide and designed for superior wear resistance, this tool is optimized for machining high-HRC mold steels and hardened components. The long neck structure allows for extended reach in deep or complex cavities, while the corner radius improves tool strength and edge durability.

Corner Radius Design Reduces Edge Chipping and Enhances Tool Life
Compared to sharp-edged tools, the reinforced corner radius minimizes stress concentration and delays edge breakage—especially important when machining hardened materials. It delivers longer tool life and consistent part quality over extended runs.

2-Flute Geometry Optimized for Chip Evacuation and Finishing Control
With wide flutes and fewer edges, the 2-flute design improves chip removal, reduces cutting heat, and provides better control in tight-radius or fine-detail finishing applications. It’s particularly effective in high-precision mold core and cavity machining.

Long Neck + Short Flute Ratio Ensures Stability in Deep Features
Engineered with a balanced neck-to-flute ratio, the tool maintains high rigidity even during deep reach operations, reducing tool deflection and vibration. Ideal for mold inserts, narrow walls, and ribs requiring excellent dimensional control.

High Red Hardness Coating Supports High-Speed and Dry Machining
Applied with a thermal-resistant nano-coating (e.g., HG), the tool retains edge sharpness at elevated temperatures, enabling dry or MQL (Minimum Quantity Lubrication) machining—supporting both performance and sustainability goals.

Cutting Parameters Provided – Reduce Setup Time, Improve Consistency
Each tool includes tested cutting data optimized for hardened steels, covering speed, feed, and depth of cut. This helps operators shorten trial-and-error setup, stabilize the cutting process, and maximize overall machining efficiency.
