Technical guidance & FAQs

Applications and materials

WIDIA Top Cut 4 V38 periphery inserts are replaceable cutting components for the matching Top Cut 4 drill-body seat. The V38 geometry addresses long-chipping materials; select the grade separately for the actual workpiece.

Choosing a configuration

Match the periphery position, insert size and complete V38 catalog designation to the body. Compare the listed grade as well as insert dimensions: the same geometry designation can be offered in different carbide grades.

Compatibility and use

Use this insert only in the manufacturer-listed periphery seat and matching size. Center and periphery references are distinct, and grade suitability cannot be established from geometry or seat size alone. Confirm both insert positions when assembling a complete drill.

When should I consider V38 geometry?

The manufacturer positions V38 for long-chipping materials. Select the exact grade and cutting guidance for your material and setup.

Can a periphery insert replace the other position?

Use the periphery insert in the seat specified for it. The other drill position has its own catalog reference and must be selected independently.

Is the grade part of the ordering choice?

Yes. Match the full material number and grade, not just geometry and seat size. Different grade offerings are not automatic substitutes.
