How to Setup and Use Round Over Bits on a CNC Router
The roundover router bit milling cutters create a smooth, convex profile on the edge of a workpiece, replacing a sharp edge with a smooth, softer, and more decorative quarter-round shape. They are essential tools for finishing the edges of furniture, tabletops, and cabinets, and are available in a variety of radii (i.e., the size of the curve) to create effects ranging from a slight softening of the edge to a more pronounced rounded profile.

Radius:
The main characteristic of a roundover bit, indicating the size of the rounded edge it creates.This data is not fixed and can be customized according to your requirements. Common sizes include 1/8", 1/4", and 3/8" radii.
Bearing:
Depends! if you need it work with your CNC machines,maybe better not with bearing, we usually use it work with hand-hold machines,The ball bearing at the bit's end rides along the edge of the material.
Material:
The mainstream material in the current market is tungsten carbide.However, there are many different types of quality.
Quality:
The appearance doesn't have much difference, or it's exactly the same. But please note the material source and thickness of the tungsten steel blades of them.These are the main reasons for the wide range of market prices.
