Stone Splitter Ponchiotti Ø28

The wedge set offers a simple and effective method for precisely separating natural stone without mechanical splitting techniques. The set consists of two springs and a splitting wedge. For the most common application with medium-hard stones, a precise drilling is recommended. For harder materials, a 2 mm larger hole ensures optimal splitting effect. The drill holes are made along a previously marked splitting line using a hammer drill. It is important that the holes run parallel and are drilled at even intervals. The depth of the holes should exceed the length of the wedges to provide enough clearance for the wedge lift. The application involves inserting the springs into the drill holes, one on each side of the intended break line. The wedges are then evenly driven in with a hammer or mallet. An even driving of all wedges ensures a clean separation. For very tough rock types, it may be necessary to work along the break line with a splitting iron. For more control over the break line, a surrounding groove with a pointed iron is additionally recommended. Depending on the type of rock, the number of wedges and the spacing of the drill holes vary. Brittle materials like marble require fewer wedges, as the break energy is distributed more evenly. Harder stones like serpentine or dense limestone require closer drill spacing and a higher number of sets. The need for wedges also increases with large-format stone blocks to achieve a controlled separation.
