The 90-degree bent nose gives the technician direct access to retaining rings on shafts and bores where a straight-nose tool cannot reach cleanly. The plier handles rings ranging from 3\/4 inch to 2-3\/64 inches in diameter and has an overall length of 6-3\/4 inches. The body is forged steel and oil-hardened for durability under repeated shop use. Handles are non-slip plastic. This tool is used by machinists, mechanics, HVAC technicians, and industrial maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThe 46 21 A21 is suited for external retaining ring service on shafts, gearboxes, motor assemblies, fan hubs, and similar mechanical components in both residential and commercial maintenance environments. The 90-degree tip angle makes it especially practical in confined spaces where straight access is limited. The 1.80 mm tip diameter and 0.0700-inch tip size provide positive engagement with standard external circlip ears. This plier covers the most commonly encountered external ring sizes in light-to-medium industrial and HVAC field service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBent 90-degree nose for access in tight or angled installations\u003c\/li\u003e\n  \u003cli\u003eCovers external ring diameter range of 3\/4 inch to 2-3\/64 inches\u003c\/li\u003e\n  \u003cli\u003eForged steel body, oil-hardened for extended service life\u003c\/li\u003e\n  \u003cli\u003eNon-slip plastic handles for controlled grip\u003c\/li\u003e\n  \u003cli\u003eFixed tip style with 1.80 mm tip diameter for positive circlip engagement\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 5254 B standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with external retaining rings (circlips) in the 3\/4 inch to 2-3\/64 inch diameter range on shafts and mechanical assemblies requiring a 90-degree bent-nose approach.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is used by mechanics, machinists, and service technicians working on rotating assemblies and mechanical equipment. Always relieve any spring tension or mechanical load on the assembly before removing or installing a retaining ring. Wear eye protection when spreading or compressing circlips, as rings can release suddenly. Do not apply excessive force beyond the designed ring diameter range, as over-spreading a circlip can permanently deform it.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Type\u003c\/strong\u003e: External Retaining Ring Pliers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Diameter Range\u003c\/strong\u003e: 3\/4 inch to 2-3\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 1.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Size\u003c\/strong\u003e: 0.0700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Type\u003c\/strong\u003e: Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Bent Nose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel (forged, oil-hardened)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Plastic (non-slip)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 5254 B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.295 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KNIPEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 46 21 A21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KNIPEX","offers":[{"title":"Default Title","offer_id":51539106234674,"sku":"46 21 A21","price":52.83,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7561a1fa13fd824c41fb0a058092c03d.jpg?v=1785834765","url":"https:\/\/voomisupply.com\/products\/knipex-46-21-a21-external-retaining-ring-pliers","provider":"Voomi Supply","version":"1.0","type":"link"}
