12.7 × 4.76 × 0.2 mm inserts
Indexable turning inserts whose three key dimensions coincide: inscribed circle d1 = 12.7 mm (0.5 in), thickness s = 4.76 mm (0.187 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.
All 1 designation here use the same shape (C). Confirm clearance, tolerance and holder on the model page; brand chipbreaker suffixes and grades change performance, not pocket geometry.
