The bosch pro die grinding stone is a mounted point designed for precision grinding and deburring of hardened and non-hardened steel in confined or awkward areas. Mounted points are the go-to solution when standard grinding wheels simply can't reach. Their compact dimensions and varied shapes make them ideal for working on small components with irregular profiles or difficult access points common challenges in metalworking, fabrication, and engineering applications. This individual mounted point is made from premium abrasive grains with a vitrified bonding, delivering the strength and durability needed for consistent performance on tough steel. The 6mm cylindrical shank is compatible with standard three-jaw drill chucks, making it straightforward to fit to a die grinder or rotary tool.
