WEKA SR65 Jumbo – The 7.500 W high-end jumbo core drilling motor for extremely heavy concrete drilling
The WEKA SR65 Jumbo diamond core drilling machine was developed specifically for maximum stress in demolition, specialist civil engineering and for drilling and sawing service providers. Equipped with modern switched-reluctance technology (SR motor), this professional machine with 7.500 watts rated power delivers the torque required for extreme large and deep drilling from Ø 120 mm to 500 mm in heavily reinforced concrete.
The most important advantages of the WEKA SR65 Jumbo at a glance:
- Maintenance-free SR motor: No carbon brushes and no rotating windings – extremely durable, robust and low-wear in continuous use.
- 6 practical speed stages: Allows the ideal matching of cutting speed to large core bit diameters.
- Massive M33/3 holder: Guarantees safe and extremely stable power transmission even at the highest torques.
- Patented water cooling: Permanently protects the motor from overheating and ensures an excellent power-to-weight ratio.
