9.525 × 3.97 × 0.2 mm inserts
Indexable turning inserts whose three key dimensions coincide: inscribed circle d1 = 9.525 mm (0.375 in), thickness s = 3.97 mm (0.156 in), nose radius rε = 0.2 mm (0.008 in). This is the dimension set behind an “equivalent insert” search — read the interchange note before substituting.
2 designations across 2 insert shapes (C, D) 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.
