Description:

The Dongcheng DJS02-10 500W Tapping Machine is a professional corded electric threading tool designed for creating accurate internal threads in metal components during fabrication, mechanical assembly, machinery maintenance and engineering workshop operations.

Powered by a 500W electric motor, the DJS02-10 provides controlled forward and reverse rotation for tapping pre-drilled holes using compatible machine taps.

The machine features a forward no-load speed range of 0–580 RPM and a reverse no-load speed range of 0–1,000 RPM, allowing operators to control the tapping process and withdraw the tap after threading.

The Dongcheng DJS02-10 supports M4–M12 tapping in cast iron, aluminium and copper, while its specified tapping capacity in steel is M4–M10. This material-specific capacity makes it suitable for a range of professional metalworking and mechanical maintenance applications.

One of its distinguishing features is the drill-chuck configuration, designed to hold compatible tapping tools using the appropriate mounting arrangement. This differs from the Dongcheng DJS10 model, which is commonly marketed with a jaw-chuck configuration.

Its forward and reverse operation supports controlled thread cutting and tap withdrawal, helping operators perform repeated threading operations with appropriately selected cutting tools.

With a 2.6kg net weight, the DJS02-10 offers a manageable handheld configuration for workshop and maintenance applications.

The machine is suitable for creating threaded holes in brackets, machine components, fabrication assemblies, maintenance parts and other suitable metal workpieces.

The Dongcheng DJS02-10 500W Electric Tapping Machine is a practical solution for metal fabrication workshops, engineering departments, industrial maintenance facilities and professional applications requiring internal metric threading.

Motor & Performance Specifications:

Manufacturer Specification Note:

The Dongcheng product catalogue specifies 500W rated power, 0–580 RPM forward speed, 0–1,000 RPM reverse speed and 2.6kg net weight for the DJS02-10.

The manufacturer specifies different tapping capacities according to workpiece material:

• Cast Iron, Aluminium & Copper: M4–M12
• Steel: M4–M10

The product should not be advertised as supporting M12 steel tapping without additional manufacturer approval.

The drill-chuck configuration is identified in the supplied product description and Pakistani distributor listings. Exact chuck jaw capacity, tapping-tool shank compatibility, rated operating voltage, frequency and additional electronic functions should be confirmed from the actual product.

Automatic tap reversal, autocorrection and electronic overload shutdown have not been independently confirmed for this specific model and should not be advertised as standard functions.
