SKU SR-75 Categories , Tag Brand:

The WEKA SR75 Core Drill is a professional-grade, high-performance wet core drilling machine built for demanding construction and civil works. Powered by a robust 7.5 kW water-cooled SR motor, it delivers an impressive output of around 5.7 kW and 15 finely tuned speed steps for precise control across a wide range of drilling diameters — from approximately 150 mm up to 900 mm in concrete.
