Cylindrical hole · 2-face chipbreaker in base type. Outer envelope follows nominal IC, thickness and cutting-corner radius. Dashed circles are mounting symbols, not bore dimensions. Chipbreaker, edge preparation, tip construction and coating are not depicted. This is not a product photograph.
Separate scales for the three views. S is measured between the top and bottom reference planes. The side section shows the outer envelope only. Minor corners, bore/countersink dimensions, chipbreaker and edge preparation require the exact manufacturer drawing.
The inch column is mm ÷ 25.4, rounded to four decimal places. This is not an ANSI designation conversion. Product tolerances and clamping dimensions are not inferred.
VNMG 160404 versus VNMG 160402
radius: 0.2 → 0.4 mm. The nominal IC and thickness are unchanged.
SUS440 wet external-turning case; not all stainless conditions. Application evidence is attached to this full product, not every insert sharing the base code.
Shape, clearance, configuration and nominal code tables only. No grade, usable-edge count, catalogue availability or acceptance tolerances inferred. Values labeled “code table” are interpretations of a designation, not measurements of a delivered product. Product-row values are reported separately, including differences in printed precision.
