Unibor E4000 Electric Magnetic Drill Product Guide

The Unibor E4000 Electric Magnetic Drill is a magnetic drilling machine designed primarily for drilling into steel and other ferrous materials using annular cutters, twist drills, and countersinks. It solves the job problem of creating precise, clean holes in structural steel and metalwork where portable, stable, and efficient drilling is needed, particularly in fabrication, construction, or industrial maintenance settings.

This type of magnetic drill is commonly used on steel beams, pipes, and plate metal where a stable, magnetically secured drill base enables accurate hole making without the need for complex fixturing. The electric motor and magnetic base combination allows the operator to perform core drilling, twist drilling, and countersinking in confined or vertical positions with greater control. It is well suited for on-site drilling and metal shop work where portability, adaptable speed settings, and cutter versatility improve workflow. Features like the LED work light and quick-release handles support practical usability during longer shifts or in low-light environments.

Where This Is Used

• Structural steel fabrication and erection sites
• Metalworking shops and industrial maintenance facilities
• Pipework installation and repair
• Heavy machinery and equipment manufacturing requiring precision holes
• Shipyards and offshore platforms for steel drilling tasks

Key Details

Selection Notes

From a selection standpoint, the deciding factors usually include the size of the holes to be drilled, material thickness, and power availability. The Unibor E4000 handles drilling diameters up to 2 inches and depths up to 2 inches, making it suitable for moderate metal fabrication tasks. Confirm the substrate is ferrous for magnetic adherence and ensure electrical power supply compatibility. Consider the type of drill bits required for your job—annular cutters for fast, large-diameter holes; twist drills for through-holes; countersinks for preparing bolt heads or rivet holes. For jobs needing precision and reliable holding power on vertical or overhead steel surfaces, the magnetic base offers significant advantages over conventional drill presses or hand drills. The inclusion of DrillSmart technology helps avoid premature cutter wear, so job productivity is not hindered by cutting tool failure.

Drill Setup Notes

When setting up, verify that the magnetic base mounts securely to a clean, flat steel surface free of rust, oil, or paint that could reduce holding strength. Position the drill to allow sufficient clearance for handle operation and bit changes. Utilize the two-speed gearbox to balance drilling speed and torque according to cutter diameter and material hardness. The LED work light can help in poorly lit conditions, improving accuracy. After each use, clean metal debris from the drill and check cutter condition. Regular inspection of electrical connections and magnetic base integrity should be part of maintenance routines to ensure consistent performance and safety on the job.
