9.525 × 3.18 × 4.763 mm inserts

Indexable turning inserts whose three key dimensions coincide: inscribed circle d1 = 9.525 mm (0.375 in), thickness s = 3.18 mm (0.125 in), nose radius rε = 4.763 mm (0.188 in). This is the dimension set behind an “equivalent insert” search — read the interchange note before substituting.

All 1 designation here use the same shape (R). Confirm clearance, tolerance and holder on the model page; brand chipbreaker suffixes and grades change performance, not pocket geometry.
