Where this radius sits
The CNGA 1606 group in this directory has 3 entries, from 0.8 to 1.6 mm radius. This sits between the smallest and largest listed radii.
Confirm the part contour and tool compensation for 1.2 mm. A radius change does not establish surface finish, cutting data or holder compatibility.
