DMT W250FCNB Double-Sided Diamond Whetstone 250mm Fine Coarse

The W10 double-sided diamond whetstone is designed for high-precision sharpening across a wide range of tools. It features a rigid, lightweight construction and dual diamond surfaces that provide consistent, even sharpening. Use water for lubrication to avoid oil, smell, or mess, and to hone hard materials such as carbide and steel. The grit indicators are color-coded at one end: Red for Fine grade 600 (25 micron) and Blue for Coarse grade 325 (45 micron), with Black, Green, and additional codes referenced for extended product variants. The Red side targets woodworking tools, carbide tooling, router bits, and kitchen knives, while the Blue side handles general carpentry tools, chisels, tin snips, and other cutting implements. This combination promotes faster sharpening than traditional stones and is built for durable, long-lasting performance.
