VNMG 160408Nominal geometry

IC 9.525S 4.76R 0.8mm

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.

Where this radius sits

The VNMG 1604 group in this directory has 6 entries, from 0.2 to 2.4 mm radius. This sits between the smallest and largest listed radii.

Confirm the part contour and tool compensation for 0.8 mm. A radius change does not establish surface finish, cutting data or holder compatibility.
