Built from submicron-grade carbide, it delivers the edge retention and rigidity needed for tight-tolerance groove work in small-diameter bores. The tool cuts in the left-hand direction, with a groove width of 0.046 inches and a minimum hole diameter capacity of 0.090 inches. Overall length is 1.5 inches with a 1\/8-inch shank diameter. Machinists and tool-and-die professionals use this tool on CNC lathes and boring operations where precision snap-ring or retaining-ring groove placement is required.\u003c\/p\u003e\u003cp\u003eThis grooving tool is suited for internal retaining ring groove applications in small bores, particularly where access is limited and a compact tooling profile is necessary. The 1.25-inch shank length provides secure clamping in standard collet or tool holders, while the 0.030-inch projection controls deflection at depth. Maximum hole depth reaches 0.669 inches, making it appropriate for through-bore and blind-bore groove work in small components such as valve bodies, hydraulic fittings, and precision machined housings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for edge retention in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting direction for specific bore orientation requirements\u003c\/li\u003e\n\u003cli\u003e0.046-inch groove width sized for retaining ring fitment\u003c\/li\u003e\n\u003cli\u003eMinimum bore entry of 0.090 inches enables use in very small-diameter holes\u003c\/li\u003e\n\u003cli\u003e0.030-inch projection limits tool overhang and reduces deflection risk\u003c\/li\u003e\n\u003cli\u003e1\/8-inch shank diameter fits standard small-bore collet and tool holder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style grooving tool for use in CNC lathes, turret lathes, and boring machines equipped with tool holders accepting a 1\/8-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and serviced by machinists and tool-and-die technicians. Ensure the machine spindle is fully stopped and all motion is locked out before changing or setting tooling. Secure the 1\/8-inch shank fully within the collet or tool block to the manufacturer-specified engagement depth to prevent pullout. Confirm cutting direction and tool orientation match the machine setup before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.046 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 0.090 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Hole Depth\u003c\/strong\u003e: 0.669 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GT045-4A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52074663051570,"sku":"GT045-4A","price":53.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/715cceb9f74b5b782e9bfaa823a775bc_1c8b3a63-7d40-41aa-a8ee-a61a35cc5cfc.jpg?v=1790051320","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-gt045-4a-retaining-ring-grooving-tool","provider":"Voomi Supply","version":"1.0","type":"link"}
