A 48 tooth blade gives fine and accurate finishes with very little breakout in laminates. Rail adjustment allows the saw to be adjusted accurately to the rail. The anti kickback function stops the saw from moving backwards along the rail and from climbing out of the work piece when making plunge cuts. Variable speed allows the correct speed to be set to match different types of material. Full wave electronics maintain a constant speed under heavy load. The enclosed guard gives a 90-Percent dust extraction capability.55mm depth of cut allows the trimming and sizing of most common door sizes.
