porraspora

ø1: 6.0mm, ø2: 26.75mm, 8 steps 90°: 6 - 9 - 11.4 (PG7) - 14 (PG9) - 17.25 (PG11) - 19 (PG13.5) - 21.25 (PG16) - 26.75 (PG21), ø3: 10.0mm, L1: 75mm, The CBN ground and spiral flutes: quiet running and high cutting performance, optimized chip flow protects the cutting edges and reduces built-up edges and cold weld marks: even long non-breaking chips will be removed easily, cone makes it easier to withdraw the tool from the materiaali
HSS-TiN
TiN-coating: wear resistant titanium nitride coating: increased hardness, very low friction coefficient, optimal service life, split point, cooling is not necessary, but recommended
