FAQ

1:What is a corner radius end mills?

A corner radius refers to the rounded transition between two intersecting surfaces or edges, instead of a sharp 90° corner.

In machining and tooling, it usually means the small radius added to the edge of a tool or a workpiece to improve strength, durability, and surface quality.

Common corner radius sizes: R0.2 / R0.5 / R1.0 mm, etc.

2:What is the best practice for corner radius end mills ?

When nesting rounded objects, avoid using the same corner radii for both objects. This can make the corners look unbalanced. Instead, adjust the corner radii to be proportional to each other; this is called optical roundness.

3: Do you support customization?
Yes we support OEM & ODM service including specs. customization according to customers' drawing(or we can help design what you want), laser LOGO on products, LOGO sticker, customized package, etc..
