The full designation \".25.80.R.U1\" decodes as follows: 0.025 in (0.635 mm) groove width, 0.80 in (20.32 mm) maximum boring depth, right-hand cut (R), and U1 uncoated solid carbide grade — the monolithic carbide shank provides maximum rigidity for small-bore internal grooving and snap-ring groove applications. The tool features a stepped\/necked-down shank geometry visible in the photos, allowing access to bores as small as approximately 4.776 mm (as encoded in the product suffix \"4776\"), with the cutting edge ground directly into the carbide blank for precise groove geometry without an indexable insert. Typical applications include internal snap-ring groove and retaining-ring groove machining on CNC lathes and turning centers; the carbide substrate provides the stiffness required to minimize deflection in deep, small-diameter boring conditions.\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%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eGuhring\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%;\"\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eGT108.4776.020\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%;\"\u003eCatalog \/ Item Number\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e303559353\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%;\"\u003eSeries\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eGT108 Grooving Systems\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;\"\u003eGermany\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%;\"\u003eTool Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eSolid Carbide Internal Grooving Bar\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%;\"\u003eCut Direction\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eRight-Hand (R)\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%;\"\u003eGrade \/ Substrate\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eU1 – Uncoated Solid Carbide\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%;\"\u003eGroove Width\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e0.020 in (0.508 mm)\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%;\"\u003eMin.
