The SJ-250 Japanese Waterstone is a 4000 grit grinding wheel designed to provide a mirror-finish polished bevel. Its fine surface polishes the edge, giving your tools the ultimate surface finish. If you're after razor sharpness, this is the grinding wheel for you! It fits the Tormek T-8 and all earlier machine models with a 250 mm (9 7/8") diameter grinding wheel.
The SJ-250 Japanese Waterstone is ideal for sharpening hand tools such as woodcarving tools, knives, scissors, plane irons, and chisels. It’s perfect for craftspeople who need minimal steel removal and a high-quality finish. While it delivers an incredible surface finish, it's not intended for reshaping tools. If your tool requires a new edge, first use a coarser grinding wheel and then use the SJ-250 Japanese Waterstone to give it a perfect final polish.
This unique stone composition ensures an extremely long service life, and often, you won't need to use a leather honing wheel afterwards as the fine finish is sufficient. The grindstone’s low maintenance and durable design make it ideal for extended use.
Clean the surface of the grindstone regularly to remove fine steel particles, using the fine side of the SP-650 Stone Grader or a coarse sponge. Avoid using the coarse side of the stone grader on the SJ-250, as it can damage the grinding surface.
The SJ-250 Japanese Waterstone fits the Tormek T-8, Tormek T-7, and earlier models with a 250 mm (9 7/8") diameter and 50 mm (2") wide grinding wheel. For the compact Tormek T-4, a smaller version, the SJ-200, is available.
The SJ-250 Japanese Waterstone is the perfect grinding wheel for those who demand the finest surface finish and sharpness. Ideal for precision tools, it ensures a polished edge with minimal maintenance.
