WEKA SR68 – Universal 7.500 W SR core drilling motor for stand-mounted large-diameter drilling
The WEKA SR68 diamond core drilling machine combines the maximum power of switched-reluctance technology (SR motor) with an unprecedented speed range. With a rated power of 7.500 watts and an extremely wide drilling range of Ø 50 mm to 600 mm, the SR68 masters even the deepest holes and large openings in heavily reinforced concrete and natural stone.
The most important advantages of the WEKA SR68 at a glance:
- Maintenance-free SR motor: No carbon brushes and no rotating windings – extremely durable, robust and free of wear parts in the motor compartment.
- 18 speed stages: Allows exact matching of the cutting speed to the respective core bit diameter for minimal segment wear.
- Robust M33/3 tool holder: Guarantees excellent power transmission and stability at high torques.
- Patented water cooling: Effectively protects the motor from overheating and ensures an optimal power-to-weight ratio in continuous use.
- Comprehensive protection: Thermal overload protection and integrated display for visual user guidance and status indication.
