About this machine.

Optimum Maschinen is a respected German company known for manufacturing high-quality machine tools built to strict European standards. Since its founding in 2003, Optimum has become a trusted name in the metalworking industry, offering a wide range of equipment including metal lathes, milling machines, drilling machines, and grinding tools. Designed in Germany and engineered for precision, reliability, and durability, Optimum machines are used across workshops, training centres, and industrial environments throughout Europe and beyond. Their products are developed with a strong emphasis on innovation, safety, and compliance with European CE regulations, ensuring exceptional performance and long service life.

The Optimum DH55G is the most heavy duty of our, high capacity, column mounted geared head drill built for industrial environments and demanding workshop use. With its robust cast iron construction and hardened, precision ground main spindle, the DH55G delivers smooth, high torque performance ideal for large diameter drilling tasks and extended duty operation. The oversized, heavy-duty worktable travels on a rack and pinion system, tilts plus or minus 60 degrees, rotates a full 360 degrees around the column, and supports workpieces up to 350kg. Supplied with a 16mm keyless drill chuck and arbor (not shown in photos), the DH55G is well suited for professional metalworking, production work, and any application requiring power, rigidity, and drilling accuracy on a larger scale.
