15.875 × 6.35 × 1.2 mm inserts
Indexable turning inserts whose three key dimensions coincide: inscribed circle d1 = 15.875 mm (0.625 in), thickness s = 6.35 mm (0.25 in), nose radius rε = 1.2 mm (0.047 in). This is the dimension set behind an “equivalent insert” search — read the interchange note before substituting.
2 designations across 2 insert shapes (C, S) 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.
