Where this radius sits

The TNMG 16T3 group in this directory has 4 entries, from 0.4 to 1.6 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.
