Twelve high-quality bits and six short wooden drill bits are always cleanly stowed and at hand as quickly as possible in the practical lid compartment cassette. The bit cassette can be used either in the lid compartment Systainer or as a separate box. Due to the integrated magnets, the bits and drill bits are held securely, allowing convenient removal and stowing. The wooden drill bits can be directly inserted into the CENTROTEC tool chuck and locked. The short drill bit length makes handling easier when drilling, for example for bore holes in panel materials or for bore holes in narrow spaces.
