The industrial box-column drilling machine is designed for drilling, reaming, countersinking, enlarging and tapping in metal. With its rigid rectangular column structure, high torque and wide spindle speed range, the CORMAK WK50 ensures precision and repeatability in both single-piece and batch production.
The CORMAK WK50 box-column drilling machine is a high-performance industrial vertical drilling machine with a tapping function, designed for intensive drilling, reaming, countersinking, enlarging holes and tapping in metal. Owing to its rigid box-column construction, high feed force and wide range of spindle speeds and torque, the WK50 industrial drill performs perfectly in both unit and serial production, ensuring precision and repeatable results.
Main machine advantages
- Large drilling capacity – up to 50 mm in steel – enables machining of large-diameter holes, and up to 55 mm in cast iron.
- Drilling machine with tapping function – allows threading operations thanks to spindle reversing and high torque.
- Precise spindle guidance – 250 mm stroke and up to 9 feed ranges (from 0.056 to 1.80 mm/rev) enable parameter adjustment according to the material and operation type.
- High spindle torque – 35 kgm – ensures efficient drilling and tapping even in high-strength materials.
- Rigid, rectangular column – provides high structural stability and resistance to dynamic deformation.
- Cooling system – coolant pump with a capacity of 12 L/min ensures optimal thermal conditions in the cutting zone.
- Intuitive operation and easy maintenance – designed for ergonomics, durability and long-term use.
Design and technology
The CORMAK WK50 box-column drill features a high-rigidity design with a vertically moving spindle head (manual travel 200 mm). A solid base and guiding system ensure precise positioning of tools and workpieces. With a 12-step spindle gearbox (31.5–1400 rpm), the machine offers a wide speed range to match optimal cutting parameters for each material. The large 710 × 490 mm worktable facilitates clamping of large or irregular workpieces.
Precision and performance
High torque and precise spindle feed adjustment ensure repeatable results in serial production. The WK50 drilling machine with automatic feed enables automated drilling and tapping, eliminating operator error. The cooling system and workplace lighting improve operator comfort and safety, especially during precision and series work.
