Electric drill Proxxon 28124 — 4500 RPM, max steel drill Ø 10 mm, AC, 220–240 V, 10 kg

Proxxon 28124 is a corded electric drill designed for workshop and light industrial metalworking. The unit runs from AC mains at 220–240 V and delivers a maximum idle speed of 4500 RPM. It is engineered to drill steel up to 10 mm diameter and combines a compact footprint with a robust build, weighing 10 kg. Practical features include a height adjustment via toothed rack with an easy-to-operate crank, a drill depth indicator with adjustable limit stop, and a spindle drive configured for increased torque at lower speeds.

Advantages

The drill uses a powerful, long-lasting direct current motor and a spindle drive with a triple belt pulley that provides roughly six times the torque in the lower rotational speed range. The spindle runs on a precision bearing for consistent concentricity and reduced vibration. A spindle head with 1/2" thread accepts industrial RÖHM chucks and the spindle also accommodates steel collets (NO 28 200). The design supports jig boring when paired with the compound table KT 150, and the overall construction emphasizes reliability for repetitive metal drilling tasks.

Suitable for

• Drilling holes in steel and other metals up to 10 mm diameter
• Workshop and light industrial metal fabrication
• Jig boring and precision drilling when used with a compound table
• Tasks requiring stable, mains-powered drilling with variable torque

• Spindle thread: 1/2" for industrial chucks; additional fit for steel collets (NO 28 200)
• Drill depth: indicator with adjustable limit stop

How to use

Secure the Proxxon 28124 to a stable workbench or dedicated drill stand and connect it to a 220–240 V AC supply. Fit a suitable RÖHM chuck or steel collet and install the required drill bit. Use the toothed rack crank to set the drilling height and the depth indicator with the adjustable stop to control drilling depth. Select a suitable feed rate and allow the direct current motor to reach operating speed before contacting the workpiece; the triple belt pulley system provides greater torque at lower speeds for controlled drilling in metal. Apply steady, even pressure and withdraw the bit periodically when drilling deep holes to clear chips.

Usage recommendations

For best results when drilling steel up to 10 mm, use sharp, correctly sized HSS or cobalt drill bits, a suitable cutting lubricant, and moderate feed to avoid overheating. When performing precision jig boring, mount the drill on a stable compound table (such as the KT 150) and verify alignment before starting operations.
