Question

Quizplus · Accepted Answer

A ballnose endmill has a half-round sphere ground on its end, making it ideal for 3D contouring and finishing complex curved surfaces. The radius and bullnose endmills have a rounded corner but do not have the same spherical shape as a ballnose endmill. A roughing endmill is used for removing large amounts of material quickly and is not suitable for finishing or contouring work.
