• Support thread restoration work where an existing thread needs to be re tapped after damage or contamination.
• Use in general mechanical engineering, plant maintenance, and metal fabrication for threaded connections.
• Apply cutting fluid suitable for the workpiece material to reduce friction and improve surface quality.
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: cắt ren, taro lại ren, and làm sạch ren depending on condition
• Holder guidance: use a Tay quay taro that keeps the tool centered and aligned.
