Porta-machos RUKO Gewindeaufnahme MK2 M5-M18

Machine shops and metalworking professionals use the RUKO GMBH Gewindeaufnahme MK2 M5-M18 to rigidly hold taps during threading operations on machines with a Morse Taper 2 spindle. It accepts metric taps from M5 to M18, providing a secure, concentric connection for accurate threads.

Key specifications

• Shank taper: Morse Taper 2 (MK2)
• Tapping capacity: M5 - M18 (metric)
• Material: High-grade tool steel
• Tool holding method: Internal thread
• Design type: Rigid tap holder
• Precision: High concentricity
• Surface finish: Ground and hardened

Why choose it

The holder is made from high-grade tool steel and ground for precise alignment, which helps maintain tap life and thread quality. Its rigid design reduces deflection during machine tapping.

Ideal use cases

• Machine tapping on lathes, milling machines, or drill presses with MK2 spindle
• Production environments requiring consistent thread depth and alignment
• Workshops needing a reliable holder for common metric tap sizes

Good to know

The holder is designed for use with taps having an internal thread (pull-type). It is not suitable for quick-change systems; taps are screwed directly into the holder.
