Unlike cutting taps, this tap displaces and forms material rather than cutting it, resulting in stronger threads with no chips to clear. Manufactured from high-speed steel (HSS) with a bright uncoated finish, it is sized for right-hand threading in the H3 thread limit class. With an overall length of 2.125 inches and a thread length of 0.75 inches, it is suited for close-tolerance production and maintenance work in metal fabrication, HVAC equipment assembly, and general trade applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in blind hole threading operations where a bottoming chamfer is required to thread as close to the bottom of the hole as possible. The 2.5-thread chamfer lead allows it to engage quickly in shallow blind holes. It is appropriate for use in soft to medium-hardness metals and is a standard choice for machinists, tool-and-die technicians, and field maintenance professionals working with 8-32 UNC fastener applications in tight-tolerance assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer with 2.5-thread lead for threading close to blind hole bottoms\u003c\/li\u003e\n  \u003cli\u003eThread forming design displaces material for chip-free, stronger threads\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in metalworking applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with standard tapping oils and fluids\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for 3B class of fit, consistent with close-tolerance assembly requirements\u003c\/li\u003e\n  \u003cli\u003eSingle oil groove design; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for blind hole tapping operations requiring 8-32 UNC internal threads in right-hand orientation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed in a compatible tap handle, tapping head, or CNC machine toolholder rated for the shank diameter of 0.168 inches. Always apply appropriate tapping fluid or cutting oil before use to extend tool life and improve thread finish. Secure the workpiece firmly and ensure the tap is aligned perpendicular to the hole to prevent tap breakage. Do not exceed the recommended feed rate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\/3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 876\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TT82850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51730203640114,"sku":"TT82850","price":29.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af46acb910fc72ba6b4bac22caaf3e10_23c75eb8-3700-4309-99ec-66ecba951e5b.jpg?v=1788713290","url":"https:\/\/voomisupply.com\/products\/titan-usa-tt82850-thread-forming-tap-8-32-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
