Weka SR 25

The electric Weka drills are made out of high quality materials. They are especially designed to last for a long time. Most of the time the drills are used by professional companies in Europe, America and even Asia. But even professional handy men use Weka drills.



  • The motor of the SR 25 is based on the principle of the switched reluctance motor (SR = switched reluctance).
  • The  SR 25 drill has 6 different speed gears. Therefore the drilling speed is easily adjusted.
  • The drill has an overload clutch. Whilst drilling, a lot of kinetic energy is created. If, for any reason something goes wrong, all this kinetic energy is released. This clutch protects the user, the drill and the equipment.
  • The motor temperature is measured and registered at all times. A  thermal protective switch will switch off safely when the maximum temperature is exceeded..
  • The  SR 25 has an oil pump, this ensures optimal gear lubrication for high efficiency, high durability and less maintenance. The new and highly  effective oil pump takes ensures optimal lubrication for the first fast step of gear, even in vertical operation.
  • The SR 25 has a water cooling system. The  water flow is  controlled through the interspace between the motor case and the case sleeve. With this  arrangement the electrical part is completely separated from the water and thus  the electrical safety is guaranteed. Therefore it is even possible to drill upside down.
  • The drill has an antifriction-element. This  ring ensures that the drill bit can be easily removed after using the drill.
  • In comparison with most drills, which have a plastic housing, the Weka hand drills are made out of steel and aluminum. This improves the lifetime of the equipment.
  • The Weka drills comply with the European safety regulations.
