Good Starter useless Box

The box, however, I feel as special, have unpacked the stuff and since then in the much smaller but still better box that was at the Bosch 10.8V GRO here.

Who really needs the plastic discs and / or wants to try the thinner blades times for which the box is good.
However, if you already know most and abundant metal to be cut can equally buy the following products:
1. DSC406 - SpeedClic (arbor + 2 blades)
2. 2.615.S45.6JD SpeedClic (12 blades in a really handy container)

Would then be 14 cutting discs plus arbor for 26 euros, instead of 6 + 2 'Half' blades plus arbor for 19 Euro.

Oh yes: plastic can also edit quite well with the metal disks. Could the toilet box easily cut out various webs / milling, cutting tubes and so on.
