PRO GNF20-40: Further information

Product Highlights

Electricians often face challenges cutting grooves into walls or ceilings due to underpowered tools that struggle with different materials and lack ergonomic design. The GNF20-40 corded wall chaser, equipped with a 2000 W brushless motor, is built for professionals who need excellent performance for tough jobs. Its robust yet compact design allows you to work close to edges, while clear markings help position cuts accurately. The ergonomic handle arrangement keeps you comfortable in all positions and directions, reducing strain during intensive use. With the GNF20-40, dust extraction is seamless thanks to the Bosch Professional Click & Clean interface, keeping your workspace cleaner. You can also easily adjust the cutting depth, cutting width, and change discs without the need for any additional tools, thanks to toolless operation of all tool settings.

Equipment & Application

The GNF20-40 is ideal for use with two diamond cutting discs to mill grooves into walls or ceilings for flush-mounting cables, cable conduits, or water and heating pipes. With this corded wall chaser, you’ll be able to cut up to 40 mm deep with a smooth feed across masonry, sandstone, or concrete.

Additional Information

For peace of mind, you can rely on the protective features of the GNF20-40 corded wall chaser - such as the PROtection switch, brake function, and restart protection.
