1. PRECISION DURABILITY Crafted with fine workmanship and advanced inner hole grinding technology, this CNC milling tool holder ensures exceptional accuracy with a tolerance of 0.05mm. The quenching and hardening process enhances its strength, making it robust and longlasting for heavyduty industrial applications. 2. LONG SERVICE LIFE Designed for prolonged use, this tool holder undergoes heat treatment in a vacuum quenching furnace, significantly improving its hardness (58±2HRC). The enhanced durability ensures consistent performance even under speed operations (12000RPM), reducing the need for frequent replacements. 3. PROOF WEAR RESISTANT The tool handle features a protective coating that prevents and minimizes wear. This not only extends the lifespan of the holder but also safeguards your CNC spindle from damage, ensuring smooth and efficient machining processes. 4. STRESS RELIEF TECHNOLOGY Through longterm thermal treatment, this tool holder effectively eliminates internal stress caused during grinding. This results in stability and precision, making it ideal for demand CNC machining tasks.
