{"product_id":"tormek-sg-250-supergrind-replacement-grindstone","title":"Tormek SG-250 Supergrind Replacement Grindstone","description":"Tormek SG-250 Supergrind Replacement Grindstone offers the perfect balance of efficient steel removal, smooth surface finish, and long-lasting durability. This grinding wheel is designed to cut all types of tools and steel qualities, including high-speed steel (HSS), with exceptional efficiency. Its unique stone composition, combined with the Stone Grader SP-650 (sold separately), provides two different cutting actions in one stone. The Stone Grader polishes the grindstone surface from its standard 220 grit to a finish comparable to a 1000 grit stone, allowing you to perform both fine sharpening and initial shaping with the same jig setting. This original grindstone is ideal for a wide range of materials, from carbon steel to high-speed steel, making it the go-to choice for those seeking both effective steel removal and a fine finish. It fits Tormek T-8, T-7, and earlier models with a 10\" (250 mm) stone diameter.\n\nModel Number: SG-250","brand":"Tormek","offers":[{"title":"Default Title","offer_id":46631580598435,"sku":"19188","price":305.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2469\/7763\/files\/a54561d9f897242ddf30078cd1c24791e677c280_19188_1_H.png?v=1775854737","url":"https:\/\/www.hartvillehardware.com\/products\/tormek-sg-250-supergrind-replacement-grindstone","provider":"Hartville Hardware","version":"1.0","type":"link"}
