4HRE 65 1.0xD4x20x50-long neck

Description

4HRE 65 1.0xD4x20x50-long neck end mill is high-performance cutting tools specifically designed for machining ultra-hard materials, such as hardened steels up to 48-55 HRC (Rockwell Hardness C). These tools are made from premium-grade carbide, offering excellent wear resistance, high heat tolerance, and long tool life even under demanding conditions.
Key Features:
• High Hardness Capability: Engineered to cut materials up to 48-55 HRC, such as hardened tool steels, die steels, and other tough alloys.
• Long Neck Design: The extended neck allows for deep cavity milling, high-precision contouring, and improved accessibility in complex mold and die applications.
• Micro-Grain Carbide: Constructed from ultra-fine carbide particles to enhance strength and edge retention.
• Advanced Coatings: Often coated with high-performance layers such as BLUE NANO to improve heat resistance and reduce friction.
• Tight Tolerances: Manufactured with extremely tight tolerances for precision machining in industries like aerospace, medical, and mold & die making.
Applications:
• High-speed and high-precision machining of hardened steels
• Mold and die making with deep cavities or narrow slots
• Engraving, fine contouring, and finishing in high-hardness alloys
Benefits:
• Reduces tool change frequency due to extended life
• Provides excellent surface finishes and dimensional accuracy
• Minimizes vibration and tool deflection, even at long reach
