Inserts with inscribed circle d1 = 12.7 mm
20 catalogued ISO 1832 insert models share an inscribed circle of 12.7 mm (0.5 in). The inscribed circle sets the cutting-edge size and the depth-of-cut capacity; thickness and nose radius narrow the list below to the exact dimension set you need.
Dimension sets at d1 = 12.7 mm
Each row groups inserts with identical inscribed circle, thickness and nose radius — the dimensional parameters behind “equivalent” searches.
