Suitable for drilling diameters up to 52 mm, with extraction connections of 24 mm and 38 mm. The adapter is connected to the hoover via these extraction connections and automatically adheres to smooth surfaces such as walls, ceilings or floors due to the vacuum of the hoover, making manual holding unnecessary. Drilling is done directly through the adapter, ensuring a neat and clean workplace and increasing safety while working. The adapter works completely independently of the tool and is compatible with almost all hoovers, including models with self-cleaning filters. Note: when used with M-class hoovers, it is important to set the hose diameter correctly for optimal dust extraction. Adapters for hoovers with different connections are available separately.
