19.05 × 4.76 × 0.8 mm inserts
Indexable turning inserts whose three key dimensions coincide: inscribed circle d1 = 19.05 mm (0.75 in), thickness s = 4.76 mm (0.187 in), nose radius rε = 0.8 mm (0.031 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 (S). Confirm clearance, tolerance and holder on the model page; brand chipbreaker suffixes and grades change performance, not pocket geometry.
