Electricians often struggle to cut grooves into walls or ceilings because they lack sufficiently powerful tools that can handle different materials and have an ergonomic design.
Equipped with a 2000 W brushless motor, the PRO GNF20-40 corded wall chaser is designed for professionals who need excellent performance for heavy-duty work. Its durable yet compact design allows you to work close to edges, and clear markings help position cuts accurately.
The ergonomic handle ensures comfort in any position and direction, reducing strain during intensive use.
With the PRO HEAVY DUTY GNF20-40, using a vacuum cleaner with the Bosch Professional Click & Clean interface is seamless, keeping your workspace cleaner.
You can easily adjust both the cutting depth and width, and change cutting discs without additional tools – thanks to the tool-free setting.
The PRO GNF20-40 is ideal for use with two diamond cutting discs for milling grooves in walls or ceilings to install cables, cable conduits, or water and heating pipes flush with the surface.
With this corded wall chaser, you can cut up to 40 mm deep into masonry, sandstone, or concrete smoothly and deeply.
Work is made safer by the PRO GNF20-40 corded wall chaser's protective features – such as a circuit breaker, braking functions, and restart protection.
