Built from high-speed steel with a bright, uncoated finish, this plug-chamfer tap is suited for general-purpose through-hole and blind-hole threading applications in machine shops, maintenance environments, and production settings. The H3 thread limit ensures consistent fit to a 3B class of fit tolerance, making it appropriate where standard thread gauge acceptance is required. With 4 flutes and a 2-15\/16-inch overall length, it handles chips efficiently in conventional tapping operations performed by hand or machine.\u003c\/p\u003e\n\u003cp\u003eThis tap is used across metalworking trades including machining, tool and die, industrial maintenance, and fabrication. It is well suited for threading steel, aluminum, and similar metals where a standard straight-flute geometry performs reliably. The plug chamfer, with its moderate lead-in, works in both through holes and sufficiently deep blind holes where full thread engagement is needed near the hole bottom. Machinists and maintenance technicians select this tap for its broad utility in manual tapping setups and CNC or turret machine applications where coolant-through tooling is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread size for fine-pitch inch thread applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides moderate 3-5 thread lead-in, usable in through and blind holes\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip control in standard tapping operations\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ground to 3B class of fit tolerance\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers durability across a range of common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish, no coolant-through requirement, reduces tooling complexity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard straight flute tap for use in manual tap handles, tapping heads, and machine tapping setups configured for 3\/8-24 UNF right-hand threading operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTapping should be performed by qualified machinists or maintenance technicians following applicable shop safety procedures. Ensure the workpiece is properly secured and the tap is aligned perpendicular to the hole before beginning the threading operation. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Do not force a tap that has stopped rotating freely, as breakage and workpiece damage may result.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\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\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008459AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734273720626,"sku":"K008459AS","price":23.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f79850f71994989e80c585959b408b4.jpg?v=1788762009","url":"https:\/\/voomisupply.com\/products\/hertel-k008459as-straight-flute-tap-3-8-24-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
