Where this radius sits
The DNGN 1906 group in this directory has 2 entries, from 1.2 to 1.6 mm radius. This is the smallest listed radius in that group.
Confirm the part contour and tool compensation for 1.2 mm. A radius change does not establish surface finish, cutting data or holder compatibility.
