The Sigma 37B2D J-Pro is a game-changing tool for tile contractors and professionals seeking to achieve perfect miter cuts on tile edges with ease. By simply sliding the J-Pro along the edge of the tile or slab, whether it's stoneware, marble, granite, or other materials, the tool ensures even processing along the entire length of the edge, accurately copying the natural curves of the slab. This level of precision would be impossible to achieve with a machine guided by a rigid guide.
One of the standout features of the Sigma J-Pro is its pre-configured 46° cutting angle, which minimizes the need for adjustments, allowing you to start working right away. With the ability to process tiles ranging from 5-20mm in thickness and 30cm to infinity in size, the J-Pro is incredibly versatile. Its low weight of just 3.8kg makes it easy to transport and handle while maintaining stability during the mitering process. The universal M14 connection allows you to mount any grinder from 700 - 1400 W, giving you the flexibility to use your preferred tools. The wide sliding support ensures perfect stability and prevents scratching, while the dust-free operation is made possible by the universal vacuum connection. The Sigma J-Pro is also designed to handle small tiles with ease, thanks to its ability to be attached to a workbench or the Sigma Work Bench using quick fasteners. Whether you prefer wet or dry cutting, the J-Pro has you covered, with the optional Water-Kit providing an adjustable water jet for maximum finishing and reduced tool wear.
