The second image confirms the cutter is marked \"R2.38 HSS CHINA,\" where R2.38 corresponds to the 1\/2 in (12.7 mm ≈ R6.35 mm — noting the marking likely reads the radius in a local convention) ground in high-speed steel for form milling convex radii on mating concave features. Convex milling cutters of this type are used on horizontal milling machine arbors to produce precise rounded convex profiles on workpieces in tool-and-die, fixture-making, and general metalworking applications. The arbor-mount design with a 7\/8 in bore accepts standard milling machine arbors; a keyway visible in the second photo provides positive drive. Made in China to standard inch dimensions.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;\"\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eMPN\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e317-0321\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCutter Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eConvex Radius Milling Cutter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eRadius\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e1\/2 in (0.500 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eOuter Diameter (OD)\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e2-1\/4 in (2.250 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eWidth\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e1\/4 in (0.250 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eArbor Hole Diameter\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e7\/8 in (0.875 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eHigh-Speed Steel (HSS)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eDrive Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eArbor mount w\/ keyway\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eChina\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"DDT2 (Cutters)","offers":[{"title":"Default Title","offer_id":49442269200599,"sku":"6901j114","price":57.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0626\/7095\/files\/value-collection-317-0321-convex-milling-cutter-1.jpg?v=1784137788","url":"https:\/\/dansdiscounttools.com\/products\/value-collection-317-0321-1-2r-x-2-1-4-x-7-8in-hss-convex-milling-cutter","provider":"Dan's Discount Tools","version":"1.0","type":"link"}
