Description:

The Dongcheng DJC30 900W Magnetic Core Drill is a professional magnetic-base drilling machine designed for precision core drilling in steel structures, metal fabrication, industrial construction and engineering maintenance applications.

Powered by a 900W electric motor, the DJC30 delivers a 450 RPM no-load speed, providing rotational performance for drilling suitable ferrous metal workpieces with compatible annular core cutters.

The machine supports a maximum 30mm core drilling diameter and a maximum drilling depth of 35mm, making it suitable for producing holes in steel plates, structural sections, metal frameworks and industrial components.

One of its distinguishing features is the 11,500N magnetic holding force, designed to secure the drilling machine to suitable ferromagnetic metal surfaces during operation. The magnetic base helps maintain positioning when correctly engaged on an appropriate workpiece.

The 140mm maximum stroke provides guided feed travel for advancing the cutting tool toward the workpiece during drilling operations.

Equipped with a 19mm straight-shank connector, the DJC30 supports compatible core drilling accessories using the manufacturer’s specified mounting arrangement.

Another important feature is Fuse Overload Protection, designed to protect the machine’s electrical system against specified overload conditions.

Unlike conventional twist-drilling machines, the DJC30 is specifically designed for core drilling only, making it suitable for applications requiring annular hole-cutting tools within its rated capacity.

With an 11.5kg net weight, the DJC30 offers a manageable magnetic drilling configuration for professional workshop and on-site fabrication applications.

Dongcheng lists a 22mm core drill bit, safety belt, open-end wrench, two hex wrenches, fuse and carbon brush among the accessories, together with plastic case packaging.

The Dongcheng DJC30 900W 30mm Magnetic Core Drill is suitable for structural steel fabrication, industrial equipment installation, metal construction, engineering workshops and machinery maintenance applications requiring precise core drilling in suitable ferrous materials.

Manufacturer Specification Note:

Dongcheng’s official product page confirms 900W rated power, 450 RPM no-load speed, 30mm maximum drilling diameter, 35mm maximum drilling depth, 11,500N magnetic holding force, 140mm maximum stroke, 19mm straight-shank connection and 11.5kg net weight.

The manufacturer identifies two main product features:

1. Core Drill Only
2. Fuse Overload Protection

The 30mm maximum drilling diameter refers to the supported core drilling capacity, not the twist drilling capacity.

The 35mm maximum drilling depth should not be confused with the 140mm maximum stroke, which describes the travel of the drilling feed mechanism.

The manufacturer does not specify variable-speed control, minimum workpiece thickness for magnetic adhesion, rated input voltage, electrical frequency or additional electronic safety functions on the referenced product page.

Application & Safety Note:

Use the DJC30 only on suitable ferromagnetic workpieces capable of providing adequate magnetic holding force. Magnetic adhesion depends on material thickness, surface flatness, cleanliness and the contact area.

Always use appropriate machine securing arrangements, including the supplied safety belt where required. Select compatible core cutters, secure the workpiece, use suitable cutting fluid and follow Dongcheng’s operating instructions.

The machine is manufacturer-specified for core drilling only.
