Widia insert 6x20mm
With the skewer irons with Widia (from the German "Wie Diamant") from BICK by the German manufacturer Bavaria Steinmetzwerkzeuge, you can rely on solid material of European quality.
The pointed iron, also called a pointed chisel or pointed chisel, is used to "rub" larger volumes out of the stone. Use a chisel that is large enough in relation to the size of your workpiece. With these chisels you can work in stone types up to and including Mohs hardness 8.
Always use an iron or soft iron hammer or mallet when using chisels with a widia tip. A hammer made of harder steel will cause strong vibrations in the chisel, which may damage the widia insert.
