Pro-112T Drilling & Tapping Machine

in stock


The PRO 112T is a drilling machine designed to drill holes with diameters of 12–100 mm (0.47–4″) by using annular cutters. It can also drill holes with diameters of 15–32 mm (0.59–1.26″) by using twist drill bits.




The PRO 112T is a drilling machine designed to drill holes with diameters of 12–100 mm (0.47–4″) by using annular cutters. It can also drill holes with diameters of 15–32 mm (0.59–1.26″) by using twist drill bits.

The machine can change the direction of rotation. This allows thread cutting by using quick change tapping system by Promotech.

Accessories allow, for example, drilling in pipes and cutting threads in holes with different diameters.

Features and benefits

  • 360-degree visual monitoring system indicates current condition of the drill and gives safety and diagnostic information
  • the most powerful motor in its class (among MT3 drills)
  • 4-speed gear with continuous speed adjustment between 50 to 510 rpm
  • intelligent speed control system maintains stable speed regardless the changing load
  • drilling with both TCT & HSS cutters and twist drill bits from small up to large diameters
  • tapping of through and blind holes with intelligent load control
  • full electronic motor control
  • electronic clutch (faster than mechanical one)
  • lightweight and extremely powerful magnetic base
  • stiffness proven design
  • tilt sensor (gyroscopic) protects against drill break away
  • intuitive control panel at top of the drill
  • large coolant container

  • Optimized highly efficient magnetic base
  • extremely powerful
  • lightweight
  • drill weight reduced to only 25 kg

360-degree Visual Monitoring System facilitates machine operation, extends the life of the drill and tools and increases work safety.

360-degree Visual Monitoring System – list of messages




ready to work (green is on)
normal work (white is on)
overheat (red is on)
emergency stop/overload (blue is on)
emergency stop/tilting the machine due to vibrations or weak surface (violet is on)


low adhesive force (green flashes)
near overload (blue flashes)


emergency stop/ voltage drop (red changes to blue)
emergency stop/ worn brushes (red changes to green)

4-speed gear enables drilling with both HSS & TCT cutters and twist drill bits from small up to large diameters. Continuous speed adjustment between 50 to 510 rpm helps to set the optimal speed depending on size of diameter, material grade and tool in use. Intelligent speed control system maintains the constant speed regardless of the changing load and increases tool life.

* For a sharp tool and mild steel with a hardness Rm < 500 N/mm2 (70,000 psi), such as St0 (S185), St3S (S235JR), or St4W (S275JO)

Steel with a hardness Rm ≥ 500 N/mm2 (70,000), such as St5 (E295), 18G2A (S355N), or 45 (C45), requires lower speeds. If the speed is too high or too low for the workpiece hardness and the type/diameter of the tool, the tool will wear faster or be unable to drill the hole.
