FAQs

A Drilling cum Tapping Machine is built to perform both drilling and tapping in one setup. It includes a forward-reverse spindle mechanism and panel board with R&F switching, allowing the operator to drill a hole and immediately cut threads without moving the workpiece to another machine.

The PDT series covers tapping capacity from 12mm (PDT20R) up to 32mm (PDT40HR) in MS. Drilling capacity on the same models ranges from 20mm to 40mm.

Back gear provides high torque at low RPM, which is critical for clean thread forming. Tapping requires slow, controlled spindle speed with maximum torque - back gear ensures the tap cuts cleanly without breaking, especially in tougher materials.

Yes. The panel board on all PDT series machines is 100% Made in India. It includes a 3-phase indicator lamp and a built-in cooling fan to protect the electrical components during continuous operation.

Yes. The PDT series machines are full-capability pillar drilling machines that also have the tapping function built in. You can use them for drilling-only operations at any time.

Fine feed is a precision depth control mechanism on the spindle. For tapping, it allows the operator to control exactly how deep the tap enters the workpiece, preventing over-tapping or tap breakage, especially on blind holes.

Yes. PRG brand machines come with a lifetime spare parts supply guarantee. All critical components are stocked and available Pan-India.

Both are 40mm drilling / 25mm and 32mm tapping machines respectively. PDT40HR is the heavy-duty variant with a larger 121mm pillar diameter, 250mm spindle travel, and a heavier build at 365kg versus 310kg for PDT40R. PDT40HR is suited for the most demanding continuous production applications.

Engineering workshops, automotive component manufacturers, fabrication units, pump and valve manufacturers, heavy equipment assembly plants, and general machining shops use these machines wherever threaded holes are required in production quantities.

Yes. PRG machines are CE certified and manufactured under ISO 9001:2015 standards. They are supplied for export through Max Machine Tools' Pan-India and international distribution network.
