The VALUE COLLECTION BOR076025 is a Boride SBA-M42 polishing stone designed for precision surface finishing and honing applications. This small-format abrasive stone measures 1/4 x 1 x 1/4 inches and is suited for fine polishing work on tool and die surfaces, molds, and machined components. Its compact dimensions make it well-suited for reaching tight geometries and detailed surface areas where larger stones cannot access. Licensed tradespeople and skilled machinists use polishing stones like this to achieve smooth, refined finishes on hardened steel and similar materials.
This polishing stone is intended for use in tool and die, mold making, and precision machining environments. The SBA-M42 designation identifies the abrasive grade and bond type, making it appropriate for finishing hardened steels and similar difficult-to-finish materials. Its small form factor is particularly useful in mold cavities, intricate die sections, and tight-tolerance machined features where controlled hand polishing is required.
Designed as an OEM-style replacement and standard-use polishing stone for precision machining, tool and die, and mold finishing applications requiring a 1/4 x 1 x 1/4 inch form factor.
Polishing stones of this type are typically used by machinists, tool and die makers, and mold technicians performing hand finishing operations. Always ensure the workpiece is secured before beginning surface work. Use appropriate personal protective equipment including eye protection when working with abrasive stones. Follow shop safety protocols and any applicable industry guidelines for abrasive tool handling.
