Daca tot s-a discutat despre oteluri rapide, are cineva si caracteristicile cutitelor vechi cu pastila lipita in functie de numele marcat pe coada (ex: P30. YT40, K10) si eventual culoarea lor (asta cand se mai vede si nu sunt ruginite).

Multumesc

Si totusi, burghiele din otel rapid RW180 si RK50 ce sunt?

 

RW 180 esre rapid Wofram 18% = Rp3

RK 50 rapid Cobalt 5% = Rp2

Sint vechile denumiri din nomenclaroeul romanesc.

Sint curios cum evaluati acele burghie, din Rp2 n`am avut romanesc nici o data.

P30 si K10 sint standarde moderne ISO, albastru pentru otel, P30 si maro pentru fonta K10.

YT40 nu stiu...

Domnule, nu ma indoiesc de faptul ca aveti dreptate, ma rog, doar partial deoarece  in standardele noastre e dat ca visiniu, ce iasa in realitate pe cutit...e cam maroniu.

Cam asa sint colorate cutitele cu placute romanesti si asa arata acel visiniu.
