Built from high-speed steel (HSS) with a bright, uncoated finish, this tap runs an 8-32 UNC thread form across a 0.75-inch thread length with a 2.125-inch overall length (OAL). The bottoming chamfer — typically 1 to 2 thread leads — allows threading to within a few threads of the bottom of a blind hole. With 4 straight flutes and an H7 thread limit, this tap suits precision threading applications in ferrous and non-ferrous materials. Machinists, tool-and-die makers, and maintenance technicians use it in manual tap handles or machine tapping setups.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance threading of 8-32 UNC fastener holes in light-gauge steel, aluminum, brass, and similar machinable materials. Typical applications include tapping holes in electrical enclosures, machine frames, fixtures, and precision assemblies where a bottoming tap is required to maximize thread engagement in shallow blind holes. It is commonly used as the final tap in a tap sequence following a taper or plug tap, or as a standalone tap in through-hole applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e4 straight flutes suited for short-chipping materials such as aluminum, brass, and mild steel\u003c\/li\u003e\n\u003cli\u003eH7 thread limit for consistent fit with standard 8-32 UNC fasteners\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness in hand and machine tapping operations\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish works with standard tapping fluids and cutting oils\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard production tap for applications requiring 8-32 UNC right-hand internal threads with a bottoming chamfer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and operated by machinists or maintenance technicians using a manual tap wrench or a machine tapping attachment. Always use an appropriate tapping fluid or cutting oil for the workpiece material to reduce tool wear and improve thread finish. Ensure the tap is properly aligned perpendicular to the workpiece before beginning the threading operation. When tapping blind holes, clear chips frequently to prevent tap breakage and verify hole depth is sufficient for the required thread length.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\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 (OAL)\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1680 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008199AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729702650162,"sku":"K008199AS","price":23.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a77aa78fd2918b6e0732e0e6709356b.jpg?v=1788708061","url":"https:\/\/voomisupply.com\/products\/hertel-k008199as-straight-flute-tap-8-32-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
