Norton 61463687040 Round Sharpening Stone Ultra Fine

Product Description

The NORTON 61463687040 is a round sharpening stone in ultra fine grade, designed for honing and refining cutting edges on hand tools, blades, and precision instruments. At 1/4 inch thick, this compact stone suits detail work and touch-up applications where a larger bench stone is impractical. Ultra fine grit removes minimal material and produces a polished, sharp edge with minimal scoring. Machinists, toolmakers, knife sharpeners, and general trade professionals keep stones like this on hand for field or shop edge maintenance.

This stone is suited for use on small cutting tools, gouges, chisels, drill bits, and similar implements that require a refined finish after initial sharpening on a coarser grit. Its round profile makes it well matched for sharpening curved or concave edges, such as the inside of a gouge or the flute of a specialty cutter. Lightweight at 0.05 pounds, it is easy to carry in a tool bag for job-site use.

Compatibility

Designed as an OEM-style replacement or standard consumable for use with hand tools, bench setups, and portable sharpening kits requiring a round ultra fine sharpening stone.

Installation Notes

Sharpening stones require no power tools or fasteners to use, but proper technique matters for consistent results. Secure the workpiece or clamp the stone as appropriate before working an edge to avoid slipping. A light honing oil or water, depending on stone type, is typically recommended to float swarf and extend stone life. Replace the stone when the surface becomes glazed or unevenly worn, as a compromised surface cannot maintain a consistent edge angle.
