6.35 × 2.38 × 0.4 mm inserts

Indexable turning inserts whose three key dimensions coincide: inscribed circle d1 = 6.35 mm (0.25 in), thickness s = 2.38 mm (0.094 in), nose radius rε = 0.4 mm (0.016 in). This is the dimension set behind an “equivalent insert” search — read the interchange note before substituting.

4 designations across 3 insert shapes (C, D, T) share these dimensions. Equal d1, s and rε alone do not make inserts interchangeable: shape and clearance must match too — a 60° triangular insert and a 55° rhombic insert at the same dimensions cut completely different profiles and seat in different holders. Rows below are grouped by shape; true geometric interchange applies within the same ISO core code across brands, as shown on each model page.
