very poor cut results

Have the blade for my Metabo KGS 216 M ordered. The delivery arrived very quickly. The very next day. Also, I was immediately surprised. The blade fits perfectly on the Metabo KGS 216 m. A spacer ring (like several Supplied) is not needed here. But then the negative: I have the version "Size: 216x30x2,6mm 60 teeth / wood", wanted to cut a couple of book-boards for making furniture. The average results are not much better than as with the included Metabo 30-tooth saw blade. But the worst, the saw blade is so hot that the cut edges are black. Had I further cut, I'm sure that the chips start to burn. Here I can absolutely advise against buying! Unfortunately come true again, "who buys cheap, buys twice!". I'm going but the expensive 50, I - order the euro saw from Metabo.
