Piedras de diamante

Diamond stones use a metal plate coated with industrial diamond abrasive, which cuts fast, stays flat, and works with water or oil. Water stones are made from abrasive particles bonded in a softer matrix; they dish more quickly but can produce a finer, more polished edge — making them a favorite for hand-tool woodworkers. Visit our learning blog for detailed sharpening guides.

Most diamond stones work best with a small amount of water or a dedicated lapping fluid as a lubricant and swarf cleaner. Dry use is possible but can shorten stone life. Check the product instructions, as some pocket-style stones are designed for dry use.

Start with a coarse grit (around 200–300) to establish the bevel if the edge is damaged or very dull, then move through medium (600) to fine (1200 or higher) grits to refine and polish. A dual-grit bench stone covers the most common needs in a single tool.

Yes. The Diamond Cross Router Bit Sharpener is specifically designed for touching up carbide router bit edges between professional sharpenings. It extends bit life and improves cut quality.

Diamond paste is used at the final polishing stage to achieve a mirror-bright, razor-sharp edge on chisels, plane irons, and carving tools. It is applied to a leather strop or a flat metal plate and produces a finer finish than most bench stones can reach.

A honing guide is not required, but it is highly recommended for consistent results, especially for beginners. The Vise Style Honing Guide holds chisels and plane irons at a fixed angle so every sharpening session produces the same bevel.

Water stones dish with use and must be periodically flattened with a diamond flattening plate. A flat stone is critical for producing an accurate flat bevel on chisels and plane irons. The DMT Dia-Flat Flattening Plate is an effective tool for this task.
