PRO-52T | Universal Tapping and Drilling Machine

The PRO-52T drilling machine is suitable for hole cutting and tapping applications. Powerful variable speed motor enables milling capacity up to 50mm (2”) and drilling capacity up to 23 mm (7/8”). Machine’s forward & reverse work modes allow thread cutting up to M20 with Promotech’s new tapping system. Two speed gearbox with continuous speed adjustment allows to set the optimal speed depending on diameter, steel grade or tool quality. Intelligent speed control system maintains constant motor speed regardless of changing loads. Innovative 360-degree LED indicator facilitates proper machine operation and increases work safety.

  • powerful motor with heavy duty 2-speed gearbox
  • Electronic Speed Stabilization System (ESSS) maintains stable speed regardless of load changes
  • tapping of through and blind holes
  • milling with TCT or HSS cutters or drilling
  • electronic clutch
  • both overload and overheat protection
  • rigid design extends tool life
  • tilt sensor stops the motor if machine breaks away
  • 360-degree visual monitoring system indicates current condition of the drill and gives safety and diagnostic information e.g. worn brushes
  • innovative smart magnet with reduced weight
  • Magnetic Field Shape Control (MFSC) provides maximum holding power on thin materials
  • Energy Saving Base(ESB) uses only 50% of its power when motor is not running
  • Semi-automatic gib adjustment enables simple, fast, correct and repeatable slide backlash settings without any expert knowledge or experience
  • intuitive control panel at top of the drill
  • large coolant container
