Where this radius sits
The SNMA 09T3 group in this directory has 3 entries, from 0.4 to 1.2 mm radius. This is the largest 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.
