6.35 × 3.18 × 0.4 mm inserts
Indexable turning inserts whose three key dimensions coincide: inscribed circle d1 = 6.35 mm (0.25 in), thickness s = 3.18 mm (0.125 in), nose radius rε = 0.4 mm (0.016 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 (W). Confirm clearance, tolerance and holder on the model page; brand chipbreaker suffixes and grades change performance, not pocket geometry.
