About this machine
This Donau DR 40 is a used radial drilling machine — sometimes referred to as a radial arm drill — built for precision drilling and tapping operations in metal and other materials. Radial drilling machines are a workshop staple wherever large or heavy workpieces need to be drilled at multiple locations without repositioning the part, as the spindle head travels along a horizontal arm that itself rotates around a vertical column. Donau is a European machine tool manufacturer with a long-standing presence in the production of drilling and boring equipment for metalworking and industrial applications.
The seller's notes describe this as a controlled fast-radial machine, serial number 1137–3, manufactured in 1988 and offered here in good condition from a location in the Netherlands. Its drilling capacity reaches 40 mm in steel (St. 60) and 50 mm in grey cast iron (GG 22), with thread-cutting capacity up to M33 in steel and M45 in cast iron. The spindle carries a steep-taper SK 40 toolholder interface, which is a robust and widely used industrial standard for radial drills of this class.
The spindle offers 18 speed steps ranging from 35 to 1,800 rpm, giving the operator a wide choice of cutting speeds to suit different materials and tool diameters. Feed rate is adjustable across five standard steps between 0.075 and 0.6 mm per revolution. Spindle travel is 200 mm. The radial arm provides a drilling radius of 350 to 1,300 mm from the column centre, with a reach (outreach) of 120 to 1,007 mm, and the spindle head can be raised or lowered by 450 mm along the column. The distance between the spindle nose and the table ranges from 350 to 800 mm, accommodating a variety of workpiece heights. The machine table measures 1,225 × 750 mm, providing a generous clamping surface.
Power is provided by a motor rated at 2/3 kW operating on 380 V. The machine weighs approximately 2,000 kg and has overall dimensions of 2,300 × 1,225 × 2,400 mm (L × W × H). Included with the machine are a thread-cutting attachment and a coolant system.
