To avoid build-ups and resulting cracks it is recommended to always use a suitable cutting fluid or cutting oil (BL 10/WK 35) when applying polishing
stones with grain size (320), 400, 600 or 900� In this way a blunting of the bond will be avoided and a constant resharpening of the cutting grains is
guaranteed�
