TC312M14 DIN Standard tapping chuck telescopic tool holder is a versatile accessory designed for tapping operations. It accepts taps from M4 up to M20 and features telescopic length adjustment to reach deep or hardtoaccess holes while maintaining alignment with the spindle. Built to the DIN standard TC312M14, this holder provides reliable performance in common workshop and production environments. Key benefits Wide tapping range: supports M4, M6, M8, M10, M12, M14, M16, M18 and M20 taps, enabling a single holder to cover multiple tapping needs. Telescopic length: adjustable extension lets you reach recessed holes or long through holes without changing tooling setups. DIN standard compatibility: TC312M14 interface ensures consistent fit with compatible spindles and tool holders, promoting reliable clamping and alignment. Timesaving operation: quickadjustable length and secure tap holding streamline setup and changeovers in busy workcells. Professional reliability: designed to perform in typical machining environments, helping improve consistency and tap quality. Key attributes Functionality: tapping chuck and telescopic tool holder for metric taps from M4 to M20. Compatibility: DIN standard TC312M14 interface for standard spindles/tooling systems. Size range: supports M4 through M20 tapping sizes. Interface specification: TC312M14 variant reference for DIN standard compatibility. Performance: designed to maintain alignment during tapping operations and accommodate varying hole depths via telescopic adjustment. Applications and use cases CNC milling and drilling: set up to tap through holes in aluminum, steel, or other workpieces where hole depth varies, using a single holder for multiple tap sizes. Prototyping and fixture work: adjustable reach allows tapping at different depths without retooling, increasing flexibility in reference fixtures and jigs. Manual or semiautomatic tapping stations: docked in machines that require quick changeovers and reliable tap retention across a range of thread sizes from M4 to M20.
