Description:

The Dongcheng DJS10 500W Tapping Machine is a professional corded electric threading tool designed for precision internal thread cutting, metal fabrication, mechanical assembly and industrial maintenance applications.

Powered by a 500W electric motor, the DJS10 delivers an adjustable 0–580 RPM forward no-load speed and 0–1,000 RPM reverse no-load speed, enabling operators to control thread-cutting operations and withdraw compatible taps efficiently.

The machine supports M4–M12 tapping in cast iron, aluminium and copper, while its specified capacity for steel is M4–M10. These material-specific ratings make it suitable for a wide range of professional engineering and metalworking applications.

One of its distinguishing features is the Auto-Correction Function, highlighted in Dongcheng’s product catalogue as a feature designed to assist tapping operations.

The machine also features an Automatic Reverse Exit Function, providing a convenient method of reversing the tapping operation and withdrawing the tap according to the tool’s operating mechanism.

Its adjustable-speed control allows operators to select an appropriate rotational speed based on the workpiece material, tap size and threading requirements.

The jaw-chuck configuration is marketed for holding compatible tapping tools using the appropriate chuck arrangement. Actual tap-shank compatibility must be checked against the supplied chuck.

For improved handling, Dongcheng lists an auxiliary handle, while the supplied accessory listing also includes a depth gauge, hex wrench and carbon brush.

With a 2.5kg net weight, the DJS10 offers a practical handheld configuration for workshop threading and maintenance applications.

The Dongcheng DJS10 500W Electric Tapping Machine is suitable for fabrication workshops, engineering departments, mechanical assembly operations, machinery repair facilities and industrial maintenance teams requiring accurate metric internal threading.

Manufacturer Specification Note:

Dongcheng’s product catalogue confirms the 500W rated power, 0–580 RPM forward speed, 0–1,000 RPM reverse speed, M4–M12 tapping capacity for cast iron, aluminium and copper, M4–M10 capacity for steel and 2.5kg net weight.

The manufacturer also lists three main features:

1. Auto-Correction Function
2. Adjustable Speed
3. Automatic Reverse Exit

The manufacturer’s Hong Kong product information specifies 220V / 50Hz for its regional DJS10. Confirm the voltage and frequency on the actual Pakistani-market product nameplate before publication.

The Jaw Chuck description is used in the supplied product information and Pakistani distributor listings. Exact jaw opening, compatible tap-shank dimensions and chuck mechanism specifications are not provided in the referenced catalogue.

The auto-correction feature should not be interpreted as guaranteeing perfectly aligned threads under every operating condition. Correct alignment, workpiece clamping and tapping technique remain essential.
