Differences in grinding tools?

Thank you Nordlys.

The question is whether so little play and minimal grinding noise are normal. The machine still has 6 months warranty, so I could send it in. Maybe Bauhaus or Obi have the device and I can compare it. That might be sensible.

This is Bosch blue. Quite possible that they don’t have it. Bosch blue is actually only for professionals. Real tool shops definitely carry it. How does he grind? Does it lie steady in the hand or wobble? If still steady, keep him. Karsten
