Mafell MAF-924222 LS 103 EC Chain Mortiser 120V (Without Chain)


The Mafell LS 103Ec is a truly impressive chain mortiser, featuring a powerful 120V or 240V motor, chain bars which do not require lubrication, and long-lasting chains.  This mortiser is available with 1.5" and 2.0" chain/bar setups to rapidly produce timber frame mortises with the sturdy FG 150 mortising stand.  The tensioning system of the LS 103Ec allows for fast chain replacement.  Even retightening the chain is quick and easy without having to remove the chain guard.
