Hole + one-face countersink · 1-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.

Where this radius sits

The CCMT 1606 group in this directory has 5 entries, from 0.4 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.
