Technical notes
- The KERNVEX DEX corner radius end mill is designed for roughing, dynamic milling, and semi-finishing titanium alloys such as Ti-6Al-4V (TC4). Its reinforced corner radius, HSR118 coating, 43° helix, 8° positive rake angle, and 87°/93° unequal flute spacing help support edge strength, chip evacuation, and cutting stability under demanding milling conditions.
- For a detailed comparison of titanium alloy roughing, finishing, and different cutter geometries, read our guide to choosing the best end mill for titanium alloy .
- Manufactured from ultra-fine micro-grain carbide with a grain size below 0.6 μm and 12% cobalt content , ensuring excellent toughness, wear resistance, and cutting stability.
- Applied with HSR118 coating, c omparable to JZR coating , offering:
- • High hot hardness and thermal stability up to 1200°C
- • Excellent anti-adhesion performance to reduce built-up edge
- • Stable cutting performance in titanium and high-alloy materials
- Design Features
- Featuring a radius-formed flute profile, 8° positive rake angle, and 43° helix angle , this design ensures stable cutting performance under high load conditions, smooth chip evacuation, and high precision machining of difficult cutting materials.
- Adopts an 43° helix angle with 87°/93° unequal flute spacing , providing a larger chip pocket. Ideal for roughing operations and dynamic milling, especially under high material removal rates.
- Application Range
- The DEX corner radius end mill is suitable for machining materials with hardness HRC 25–60 , including:
- • Titanium alloys
- • Aluminum-titanium alloys
- • Stainless steel
- • Alloy steel & carbon steel
- • Non-ferrous metals
