Two-wheel bench grinder 250W DEDRA DED7778, for dry and wet work, 150x12.7mm/200x20mm

DEDRA DED7778 two-wheel bench grinder is designed for precise and convenient processing of tools and parts made of steel, non-ferrous metals, and plastics.

It allows work both dry and wet, which enables adjusting the processing method to the material type and desired result. This makes the device suitable for sharpening as well as minor finishing tasks.

The device has two types of wheels intended for different applications. The high-speed dry wheel allows quick material removal and efficient performance of basic grinding operations. The slow-speed wet wheel provides more precise and gentle processing, keeping the material constantly cooled and reducing the risk of overheating.

The grinder can be permanently mounted to a workbench, increasing stability and reducing vibrations during operation. The additional support for the workpiece facilitates precise tool handling and maintaining the correct angle, allowing for an even and accurate finish.

Protective guards effectively shield the user from sparks during operation, enhancing safety and allowing full concentration on the work. The built-in switch with anti-restart protection safeguards the user and the device during power interruptions or voltage fluctuations, preventing uncontrolled start-up.

The sturdy metal housing stabilizes the machine and provides high resistance to mechanical damage. This makes the grinder suitable for intensive workshop use, ensuring durability and reliability in daily operation.
