Walter BLAXX-Heptagon milling cutter M3024 - with a new finishing insert - Walter Tools

[@nogum9763]

for what reason was the part removed from the table to mesure the surface roughness

[@keijoylonen3518]

Maybe 6.3 Ra or worse. Your tester is shit or not calibrated correctly

[@ariseanbu1381]

Please calibrate your roughness tester because you don't know 0.2 Ra's finish. Do cheats but not like this....
