• Thermal-Resist Alloy: Manufactured with carburized 20CrMnTi steel composition; The finish carburizing heat treatment prevents degradation during continuous CNC operate; Maintains size stability in temperature aerospace component fabrication
• Adaptive Float Mechanism: Extension bar design compensates for axial misalignment during reverse rotation; Reduces tap fracture incidents by 85% in mass production ambient; Essential for automotive transmission line threading and aluminum die-casting operate
• Surface Enhancement: Quenched thread profiles resist abrasive wear in stainless steel processing; Mirror-finished touch surfaces friction during speed tapping; Suitable for creating hydraulic valve threads and optical equipment fasteners
• Elastic Stress Relief: Controlled tensile deformation absorbs sudden torsion peak; Prevents workpiece damage when threading brittle composites; Safeguards delicate materials during electronics enclosure prototyping
• Universal Compatibility: BT40 taper fits most milling machines and CNC vertical centers; Processes threads from M2 miniature screws to M30 structural ; Compact 46 mm profile accesses tight spaces in cavity modifications
