9.525 × 3.97 × 1.6 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 = 1.6 mm (0.063 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 (T). Confirm clearance, tolerance and holder on the model page; brand chipbreaker suffixes and grades change performance, not pocket geometry.
