Multifunctional tool for drilling and turning

Multifunctional tool for improved productivity

Applications & Features

Applications

DrillingInternal turningExternal turning

Features

1. Minimum number of tools for maximum productivity

• A single TungBoreMini tool can handle multiple operations such as ID turning after drilling without exchanging the tools.
• Allows drilling and hole enlargement on various materials, instead of using a drill and turning tool.
• Can be used just like a standard ISO turning tool for ID, OD, and/or face turning application.

2. Reduced machine downtime

Multifunctional TungBoreMini eliminates tool changeover time, resulting in significantly reduced cycle time – this is especially effective in applications where individual processing time is short and quick, resulting in tremendous improvement in cycle time.
