Wide application The tool chuck is widely used in thread cutting machines, drills, milling machines, and pneumatic tools, enabling it to handle multiple machining tasks with a single component. Easy to use The round thread cutting chuck allows quick installation and removal, saving time when switching between applications and reducing downtime in busy workflows. Material and finish The lining is made of high quality carbon steel, quenched and blackened, delivering high hardness and good oxidation resistance for longer tool life. Performance and reliability Exquisite workmanship provides strong stability, resistance to breakage, and a high safety factor, ensuring reliable operation during demanding machining tasks. Size and compatibility Designed to be compatible with standard tool shanks used in thread cutting machines, drills, milling machines, and pneumatic tools. Available in standard sizes suitable for common tooling setups. Use scenarios - Thread cutting on a lathe: rapidly switch between external threading, internal threading, and finishing passes without re-tightening or re-clamping, improving cycle time and accuracy. - Drill and mill combo setups: move between drilling and milling operations with minimal downtime, maintaining consistent grip and reduced runout. - Pneumatic tool integration: deploy in portable or workshop pneumatic systems where a robust, corrosion-resistant chuck is beneficial for repeated tool changes and reliable holding.
