SUNTECHMACH D80 Brushless Electric Pipe Wrench 30-80mm 1200N.m

The SUNTECHMACH D80 is a brushless electric pipe wrench that clamps pipe from 30mm to 80mm outside diameter - 1" to 2 1/2" nominal pipe size - and turns it with 1200N.m of torque from a 900W brushless motor. It runs either on the 18V 4.0Ah lithium-ion battery or on the 18V DC power supply box, so the same tool works on site with no power and indoors on mains. At 30r/min it drives threaded joints, couplings and fittings without the arm travel of a manual wrench, and at 7.3kg excluding the battery it can still be handled overhead. It is one of nine models in the SUNTECHMACH pipe wrench family, covering 10mm to 210mm.

Key Features

• 1. Clamping Range 30-80mm (1"-2 1/2" nominal): covers nominal pipe sizes from 1" to 2 1/2".
• 2. 900W Brushless Motor: no carbon brushes to replace, with stable torque over a long service life.
• 3. 1200N.m Max Torque: high torque for threaded joints, couplings and fittings.
• 4. DC & AC Dual-Use: 18V 4.0Ah lithium-ion battery, or the 18V DC power supply box for mains operation.
• 5. 30r/min Rotation: controlled turning speed for threaded and fitting work.
• 6. 7.3kg Excluding Battery: a one-hand tool that can still be used overhead.
• 7. One 18V Platform: the battery, 3A charger and DC power supply box are shared across the SUNTECHMACH range.
• 8. 9-Model Family: 10mm to 210mm clamping range, so one platform covers the whole site.

Operation Guide

• Fit a charged 18V 4.0Ah battery, or connect the 18V DC power supply box for plug-in operation.
• Select the model whose clamping range covers the pipe outside diameter.
• Open the jaws and seat the head square onto the pipe, with the jaws on the joint to be tightened.
• Hold the body with one hand and steady the head with the other; keep hands clear of the jaw travel.
• Press the trigger and let the head rotate the pipe; the wrench holds the pipe while torque is applied.
• Release the trigger as the joint seats - do not force past the rated torque.
• Release the jaws, reposition for the next turn, and repeat.
• Remove the battery before storage or transport.

Common Faults & Solutions

FAQ

Q: What is the difference between the clamping range in mm and the inch size?

A: The mm figure is the actual outside diameter the jaws will grip. The inch figure is the nominal pipe size (NPS) of the pipe that falls inside that range - for example a 2" nominal pipe has an outside diameter of about 60mm. The two columns are not direct conversions, which is why 58-115mm is quoted as 2"-4".

Q: What does DC & AC dual-use mean?

A: The wrench runs on the 18V 4.0Ah lithium-ion battery, or on the 18V DC power supply box, which plugs into the mains. You can keep working on site with no battery, or where the battery is flat.

Q: Is the motor brushed or brushless?

A: Brushless. There are no carbon brushes to replace, which is what gives the motor its longer service life and stable torque.

Q: Why does the specification say 21V when the battery says 18V?

A: 21V is the peak voltage of the battery pack; 18V is its nominal voltage - the standard 18V-class lithium-ion platform. Both figures describe the same pack.

Q: How many batteries are supplied?

A: The catalog configuration shows two 18V 10-cell 4.0Ah lithium-ion batteries plus a 3A charger and an 18V DC power supply box. 【待工厂确认】 - confirm the final packing list.

Q: Can I buy batteries and chargers separately?

A: Yes. The battery, 3A charger and 18V DC power supply box are all available as separate items. 【待确认】 - confirm part numbers and pricing.

Q: Is it a one-hand tool?

A: Yes. The body weighs 7.3kg excluding the battery, and the head is balanced for one-hand positioning on the pipe.

Q: How long does a charge last?

A: runtime per charge depends on pipe size and torque demand; request the factory test data before publishing a figure.

Q: Can the jaws be replaced?

A: confirm whether spare jaw sets are available.

Q: What is the warranty?

A: 12 months. - confirm the warranty terms for the battery.
