Rounding cutters are used to round off edges cleanly and precisely when processing wood. This results in straight or curved edges that make the workpiece look significantly higher quality. The rounding cutter with thrust bearing R4 (where R4 stands for a radius of 4 mm) is ideal for such purposes. The milling tool has a replaceable ball bearing and two carbide-tipped cutting edges.
Thanks to the integrated ball bearing of the rounding cutter R4, no additional guides are required for milling. If you want to vary the type of edge profile, the milling attachment can also be replaced with a different ball bearing. The rounding cutter with R4 thrust bearing is compatible with RUWI table routers and common routers, hand routers with 8mm collets.
