Carbide End Mills for Mold Steel Machining

Product Detail

UEX 2-Flute End Mill for Die Steel – HRC60 High-Hardness Cutting · Nano Coating · Die Finishing Specialist

When die steel hardens and its hardness soars to HRC60, do conventional tools wear out quickly and require frequent changes?
The UEX 2-Flute End Mill is purpose-built for high-hardness die steel.
Its ultra-fine nano coating and high-rigidity substrate work in perfect synergy, keeping the cutting edge razor-sharp even when machining hardened steel. The 2-flute, large-chip-capacity design ensures smooth chip evacuation even under high-hardness conditions, preventing chip accumulation and interference.
From post-heat-treatment dies to high-hardness components – every cut delivers stable, reliable performance.

Product Features

[Designed for High-Hardness Die Steel]: Suitable for hardness range HRC55–60, specifically engineered for hardened die steel, tool steel, and high-hardness alloy steel. The substrate and coating formulation are optimized for the extreme hardness and wear resistance of post-heat-treatment materials.

[Nano Composite Coating, Thermally Stable & Wear-Resistant]: Features advanced AlTiN nano composite coating with extremely high hot hardness (oxidation resistance up to 800°C+). Under high-speed cutting conditions, it effectively blocks cutting heat, preventing edge softening and wear, increasing tool life by over 30%.

[2-Flute Design, Grooving Without Worry]: Even for high-hardness materials, UEX retains a 2-flute, large-chip-capacity design, ensuring smooth chip evacuation in high-hardness grooving and deep cavity machining, avoiding tool overheating and chipping caused by poor chip flow.

[High-Rigidity Substrate, Vibration & Chipping Resistant]: Uses ultra-fine grain carbide substrate that combines high hardness with high toughness. In interrupted cuts or uneven stock removal, it effectively resists impact and reduces chipping risk. A reinforced core thickness further enhances bending rigidity for more stable side milling.

[Precision Edge Preparation – Micro-Edge Honing Technology]: Tailored for high-hardness materials, precision edge honing strengthens the microscopic cutting edge while maintaining sharpness, achieving the ideal state of "cutting hard material like butter" without chipping.
