The OPTIMUM Optidrill DH 40GPE geared column drill is a machine tool designed for drilling, tapping and precise operations on metal workpieces. Its robust structure, smooth running and technical equipment make it suitable for mechanical workshops, maintenance departments, technical laboratories, training centres and professional users who need a stable, accurate and versatile drilling machine.

The two-stage industrial electric motor allows the machine to be adapted to different operating conditions. The 12-speed gearbox, with a range from 95 to 3200 min⁻¹, allows the most suitable speed to be selected according to drill diameter, material and operation type. Lower speeds are suitable for larger drilling diameters, tapping and operations requiring more torque, while higher speeds are useful for small-diameter drilling and faster machining.

The geared head ensures smooth operation thanks to ground gears running in an oil bath. This solution helps reduce noise, improves component life and maintains stable power transmission over time. The gear head can be tilted sideways by ±45°, allowing inclined drilling and machining on workpieces requiring a specific orientation in relation to the spindle axis.

The drill provides a drilling capacity in steel S235JR of up to 32 mm and a continuous drilling capacity in steel S235JR of up to 28 mm. The quill has a 120 mm stroke, 75 mm diameter and MT4 spindle taper. The drilling depth stop with millimetre scale allows the operator to set the working depth accurately and repeat holes at the same depth. The automatic quill feed, with 130 mm/min feed speed, supports regular machining and reduces operator effort during repetitive operations.

The thread cutting function and right/left rotation extend the machine’s application range, making it suitable not only for drilling but also for internal thread production. The conversion from coarse manual feed to fine manual feed allows better control when approaching the workpiece and during delicate machining phases, improving accuracy in precise operations.

The drilling table is large, solid and precisely surface-finished. The working surface measures 500x460 mm, with diagonal 14 mm T-slots, 360° rotation and 90° tilt. The table is adjustable via three handwheels and has an integrated length scale. By positioning the drill table correctly, a suitable working area can also be created for particularly tall workpieces, using the maximum spindle-to-table distance of 785 mm and maximum spindle-to-machine-base distance of 1210 mm.

Adjustable end stops on the cross table support repetitive work and controlled workpiece positioning. The machine base offers a 420x410 mm work area with 14 mm T-slots, useful when machining taller parts or when the base must be used as the support surface. The 115 mm column diameter contributes to structural rigidity and stability during machining.

The machine includes a height-adjustable safety guard with microswitch, an important feature for operator protection during drilling. The LED light improves visibility in the working area, making it easier to control the drilling point and tool position. The coolant pump allows cutting fluid to be used to cool the tool and workpiece, reduce wear and improve hole quality in more demanding operations.

Standard equipment includes a 1–13 mm / B16 geared drill chuck, MT4 / B16 taper adapter, M4–M3 reducing sleeve and T-nuts. These accessories allow the main drilling operations to be started quickly and help adapt the machine to different tools. Before use, it is advisable to check correct workpiece clamping, select the speed according to drill diameter and material, set the drilling depth and use coolant when required by the operation.

The OPTIMUM Optidrill DH 40GPE is a solid and versatile solution for users looking for a geared column drill that combines precision, stability and practical operation. With 12 speeds, MT4 taper, automatic feed, thread cutting function, adjustable table, tilting head, right/left rotation, coolant pump and LED light, it is suitable for professional and craft metalworking where control, reliability and repeatability are required.
