Edge trimmers are designed to trim laminate edge banding to leave a perfectly flat and square edge between the banding and workpiece. This trimmer can be used on PVC, ABS, melamine and wood veneer. The trimmer blade has an adjustable depth which can be locked in place using a large, knurled brass knob, this will allow you to cut different depths of banding in each pass. The design of the body of the trimmer uses a lip to lock onto the edge of the workpiece which means it will always sit square to give a precise finish.
