The rounding cutter RE with thrust bearing is used in woodworking to cleanly and precisely round off straight or curved edges. In this way, the workpiece is visually enhanced and also has a pleasant feel. R5 stands for a radius of 5 mm. The RUWI quarter round cutter, as the rounding cutter is also called, has a replaceable ball bearing and two carbide-tipped cutting edges. The ball bearing that is already integrated makes additional guides superfluous when milling the piece of wood. The milling attachment can also be replaced with another ball bearing. This is the case when you want to vary the design of the edge profile. Other types of rounding cutters can be bought in the RUWI online shop.
