    1.material good 2. fast shipping.3 perfect hole so my job faster.

  12. A***o

    A prima impressione non sembra così male. Frese a tazza di questa dimensione in Italia costano 10 volte in più. Daró ulteriore riscontro se sarà in grado di tagliare una lamiera di 2,5 mm con trattamento al magnesio, posterò risultato del taglio e dei denti a fine processo. Olio da taglio pronto all’uso, vediamo se la fresa fá il suo dovere.
