MST Corporation | Shrink fit holder slimline

This tool chucking system utilizes the difference in thermal expansion rates between the holder material (steel) and the cutting tool material (carbide). By performing 'shrink fitting' and 'shrink removal' at 300°C, stable precision is maintained, ensuring optimal performance. Its simple and compact design makes it ideal for mold and component machining, as well as high-speed cutting applications.

【Product Features】
• New clamping method utilizing thermal expansion: By heating and cooling, the steel holder firmly and precisely clamps the carbide tool.
• Specially developed shrink-fit steel: With 1.6 times higher thermal expansion rate and a heat resistance of 720°C, it's ideal for shrink-fit holders.
• Low-temperature shrink-fit operation: Tools can be easily mounted and removed at an average temperature of 300°C.
• No additional parts required: A simple and compact structure without collets, nuts or other fastening parts.
• Slim design: The tip section features a minimum wall thickness of 1.5mm, achieving the slimmest holder. : Prevents interference with the workpiece, providing stable machining. : Choose the optimal holder from a selection of 4,000 types. : Suitable for mold machining, parts machining, 5-axis machining, ultra-precision micro-machining, heavy-duty cutting, and more. : Contributes to improved machining accuracy, longer tool life, and reduced costs. : With a highly balanced outer shape, minimal expansion of the chucking area due to centrifugal force, maintaining strong gripping force even at high speeds. : Utilizes structural characteristics to ensure leak-free and reliable coolant supply without requiring special sealing components.
