Designed for Hardened Steels up to 65HRC — Superior Wear and Edge Resistance
Manufactured using ultra-fine grain tungsten carbide and enhanced with a high red-hardness nano-coating (e.g., TiAlN or AlCrN), this tool is optimized for machining high-HRC materials like SKD11, H13, D2, and other heat-treated tool steels. It offers excellent abrasion resistance and edge retention during prolonged cutting operations.

4-Flute Geometry for High Feed Rates and Surface Finish Quality
The 4-flute configuration increases the number of cutting edges in contact with the workpiece, enabling higher feed rates and improved material removal efficiency. This design ensures smoother cutting action, reduced vibration, and excellent surface integrity—especially suitable for finishing passes in hardened steel molds and precision components.

Flat End Geometry Ensures Precision in Slotting, Shoulder Milling, and Pocket Finishing
The flat tip delivers precise 90-degree edges and clean bottom surfaces, making this tool ideal for precision cavity milling, step finishing, and complex structural detail machining in hardened and heat-treated materials.

Enhanced Core Strength and Short Flute Design for Rigidity and Stability
Engineered with a reinforced core and short cutting length, the tool resists deflection and minimizes tool chatter—critical for high-tolerance machining in small features, narrow slots, and tight corners.

Advanced Heat-Resistant Coating Supports Dry and High-Speed Machining
The high-temperature-resistant coating ensures consistent cutting performance even under dry or minimum-quantity lubrication (MQL) conditions. This supports efficient, sustainable production while reducing coolant usage and operating costs.

Application-Specific Cutting Parameters Provided for 65HRC Materials
Samho provides precise machining parameters including spindle speed, feed rate, and depth of cut for various hardened steels, helping users minimize trial-and-error, reduce tool breakage, and achieve stable, repeatable performance.
