The GROOVER 500-LP cordless grooving machine from Leister uses a general-purpose milling cutter to mill grooves for weld seams and joints when laying resilient floor coverings of plastic (PVC, PE, PUR) and natural materials (linoleum, rubber). The cordless drive eliminates the need to reply on electric power outlets and extension cables. The risk of tripping over cables that are lying around is also minimized. It also makes switching from one room to another hassle-free and significantly quicker. The groover is supplied with two batteries. Since the charging time for a battery is shorter than the subsequent operating time, there is no downtime waiting for a battery to charge.
