Technical guidance & FAQs

Applications and materials

WIDIA VariMill XTREME regular ball-nose inch mills offer a rounded end for contouring curved features and sculpted surfaces. Four flutes, WS15PE grade and cylindrical shanks define the listed configurations.

Choosing a configuration

Choose ball diameter for the surface geometry and compare cutting depth, shank and overall length. Consider the long ball-nose family only when the required cutting reach calls for it.

Compatibility and use

Confirm holder clearance and ball-nose cutting conditions for the actual workpiece and contact region. A square-end or corner-radius cutter produces a different surface envelope.

Is this a corner-radius cutter?

No. It has the full rounded end profile of a ball-nose mill.

How should I compare regular and long versions?

Compare actual cutting and overall lengths for the selected diameter, then verify clearance to the part.

What dimensions matter for a curved feature?

Match ball diameter to the required surface geometry, then verify cutting depth, shank diameter and overall length for access and holder clearance.
