PORRASPORA RUKO Size1,TiALN 4-20mm

ø1: 4.0mm, ø2: 20.0mm, steps: 9 (90° ─ 2mm), ø3: 8.0mm, 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-TiAlN
TiAlN-coating: wear resistant titanium aluminium nitride coating: increased hardness, very low friction coefficient, optimal service life, split point, enables cutting with dry machining tools w/o cooling
