The cordless cordless cordless groove cutter Zeta P2 with integrated milling mechanism creates the interlocking P-System groove within seconds. After being inserted into the material, the milling mechanism automatically engages and performs an axial milling movement for the P-System grooves. With the Zeta P2 battery and the matching connectors, workpieces are joined very quickly, aesthetically and at all angles. The P-System depth control rotates at lightning speed so that different depths can be set for the P-System connectors: 10, 12, 14, 15 or 18. In addition to the P-System application, the Zeta P2 can be used as a standard groove milling machine for wooden slats. The advantages of the Zeta P2 battery pack over the mains-operated groove cutter are the short set-up time and greater mobility in the workshop and on the building site. The machine in the case is immediately ready for use without having to connect sockets, cable reels or extractors first. Larger workpieces in the workshop can be worked on all sides without tripping hazards or having to move a cable first. The P-System groove cutter also convinces on the construction site, operating on powerful 4.0 Ah batteries from the CAS system. Working on site is easier without the hassle of power connections or extractors.
