Norton 61463686405 Half Round Sharpening Stone Coarse

Product Description

The NORTON 61463686405 is a half round sharpening stone rated at coarse grade, designed to sharpen, deburr, and hone tool edges across a wide range of trade and workshop applications. The half round profile provides two working surfaces in one stone: a flat face for straight edges and a curved face for concave surfaces, grooves, and curved blades. It meets specification CF344, making it a referenced item for procurement and maintenance programs. Installation is not applicable — this is a hand-held abrasive tool used freehand or with a guide. Trade professionals including HVAC techs, plumbers, electricians, and general maintenance personnel use coarse stones for fast metal removal and edge restoration on worn or nicked tools.

The coarse grade makes this stone well suited for initial sharpening passes on heavily dulled blades, chisels, scrapers, and similar hand tools. The half round shape is particularly useful for sharpening curved cutting edges, gouges, and tools with recessed profiles that a flat stone cannot reach. It is equally at home in a field service kit or a workshop. The compact form factor makes it easy to carry on the job for quick touch-ups between tasks.

Installation Notes

No installation is required for this product. Use on a stable surface or hold the workpiece securely when sharpening freehand. Apply appropriate honing oil or water as a lubricant if required by the tool manufacturer to prevent glazing and extend stone life. Keep out of reach of unsupervised personnel and follow shop safety practices when handling sharp tools.
