New very fast diamond solution for drilling porcelain, very hard tiles & marble worktops etc. Cutters fit all standard angle grinders. Very aggressive. Materials: Marble, Granite, Ceremic, Porcelain, Concrete, Brick. Descriptions: Ø It can drill smooth holes without chipping and much less dust. Ø It lasts much longer than diamond core bits. Each bit typically will last dozens of holes. Applications: Ø Designed to be used dry at high cutting speed. Ø Do not put pressure on it, because life time will be shortened. If drilling multiple holes in sequence, it helps to have a cup of water to hand to dip the bit in periodically to help keep it cool. Ø Rotate the grinder or drill a little during cutting, to help clear the debris and create a cleaner, faster cut.
