CORMAK WK50

CORMAK WK50 Pillar Drill Press – Heavy-Duty Industrial Metal Drilling and Tapping Machine

The CORMAK WK50 is a high-performance industrial pillar drill press with tapping function, designed for intensive drilling, reaming, countersinking, hole enlargement, and tapping operations in metal. Thanks to its rigid rectangular body construction, high feed force, and wide range of spindle speeds and torque values, the WK50 industrial drilling machine is suitable for both single-piece production and serial manufacturing, ensuring repeatability, accuracy, and high machining efficiency.

Main Advantages of the Machine
Large drilling capacity – up to 50 mm in steel and up to 55 mm in cast iron, enabling machining of large-diameter holes.
Drilling machine with tapping function – reverse spindle rotation and high spindle torque allow efficient and precise thread cutting.
Precise spindle guidance – 250 mm spindle travel and 9 feed settings (from 0.056 to 1.80 mm/rev) allow optimal adjustment of machining parameters.
High spindle torque – 35 kgm – enables effective drilling and tapping even in high-strength materials.
Rigid rectangular column design – provides excellent stability of the drive system and resistance to dynamic deformation.
Cooling system – coolant pump with a capacity of 12 l/min ensures proper thermal conditions in the cutting zone.
Intuitive operation and easy maintenance – the machine has been designed for ergonomic use and reliable long-term operation.
Design and Technology – High Rigidity for Industrial Applications

The CORMAK WK50 pillar drill press is based on a highly rigid construction with a vertically adjustable spindle head featuring 200 mm manual travel. The solid machine body and precision guide system ensure accurate positioning of tools and workpieces.

The 12-speed spindle gearbox (31.5–1400 rpm) provides a wide operating range, allowing optimal cutting parameters to be selected for different materials and machining operations.

The large 710 × 490 mm worktable makes it easier to mount large and irregularly shaped workpieces, increasing the machine’s versatility in industrial environments.

Precision and Working Efficiency

High spindle torque and precise feed adjustment ensure excellent repeatability during serial production tasks. The CORMAK WK50 drill press with automatic feed enables semi-automatic drilling and tapping operations, reducing errors caused by manual operation.

The integrated cooling system and work lighting improve operator comfort and safety, especially during precision machining and long production cycles.
