Where this radius sits
The TPGN 16T3 group in this directory has 1 entries, from 0.8 to 0.8 mm radius. This is the smallest listed radius in that group.
Confirm the part contour and tool compensation for 0.8 mm. A radius change does not establish surface finish, cutting data or holder compatibility.
