Built to the 7\/8 inch-9 TPI National Coarse (NC) thread standard, this die is used to chase and clean existing threads on bolts, studs, and threaded rod without cutting new threads from scratch. The hexagonal body allows a standard wrench or die stock to drive the tool with controlled torque. It is a practical shop and field tool for machinists, maintenance technicians, and mechanical contractors who need to salvage fasteners rather than replace them.\u003c\/p\u003e\n\u003cp\u003eThis rethread die is suited for use on 7\/8 inch diameter fasteners with a 9 threads-per-inch National Coarse pitch — a common size found in heavy equipment, structural steel connections, and industrial machinery. It is appropriate for both bench use in a machine shop and field repair work where a bolt or stud cannot easily be removed and replaced. The import designation indicates this die is manufactured to standard dimensional tolerances at an accessible price point for general-purpose rethreading tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8 inch diameter, 9 TPI National Coarse thread specification for compatibility with standard NC fasteners\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides adequate hardness for rethreading mild steel and common fastener materials\u003c\/li\u003e\n  \u003cli\u003eHex body design accepts a standard wrench or die stock for controlled manual operation\u003c\/li\u003e\n  \u003cli\u003eRethreading geometry chases and restores existing threads rather than cutting full-depth new threads\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 unit — suitable for single-use procurement or stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 7\/8 inch-9 NC externally threaded fasteners including bolts, studs, and threaded rod manufactured to ANSI\/ASME Unified National Coarse thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified mechanical technician should select the correct die stock or wrench sized to the hex body before beginning work. Secure the workpiece and apply cutting oil to the die and fastener to reduce friction and extend tool life. Run the die slowly and back off periodically to clear debris when working on heavily corroded or damaged threads. This tool is intended for rethreading existing threads and is not a substitute for a full threading die when cutting new threads from unthreaded stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 9 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: National Coarse (NC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDie Type\u003c\/strong\u003e: Hex Rethread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.96 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CHD-8750-9-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233343930674,"sku":"CHD-8750-9-I","price":19.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622113.png?v=1780097982","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-chd-8750-9-i-hex-rethread-die-7-8-9-nc","provider":"Voomi Supply","version":"1.0","type":"link"}
