Built from high speed steel with a bright, uncoated finish, this tap is suited for general-purpose threading operations where coolant-through capability is not required. The plug chamfer style provides a gradual thread entry with approximately 3 to 5 chamfered lead threads, making it a practical choice for through-hole applications. With an overall length of 2-15\/16 inches and a thread length of 1-1\/4 inches, the K008456AS is a compact, reliable option for machinists, tool-and-die workers, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for hand-tapping operations on 3\/8-24 UNF thread forms in through-hole configurations. The H2 thread limit designation indicates a tighter tolerance range appropriate for standard UNF fits. It is commonly used in machine shops, maintenance and repair environments, and production settings where manual thread cutting in steel, aluminum, and similar materials is required. The 4-flute straight-flute geometry provides good chip control in shorter-chipping materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread size with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for gradual thread entry, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for consistent, close-tolerance UNF thread fits\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute design promotes chip control in shorter-chipping materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for general-purpose use without coating-related size buildup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hand tap for 3\/8-24 UNF through-hole threading applications compatible with conventional tap wrenches and T-handle drivers accepting a 0.286-inch square drive shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance technician following standard hand-tapping procedures. Secure the workpiece firmly before tapping and ensure the tap is started perpendicular to the workpiece surface to avoid cross-threading or tap breakage. Apply an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Back the tap off periodically to break chips and clear the flutes during operation.\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\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\u003eFlute Style\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/4 inches\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\u003eShank Diameter\u003c\/strong\u003e: 0.3810 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2860 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: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008456AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728625762610,"sku":"K008456AS","price":20.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51cb7e294cfb0ea7c3453d4f3079bc56.jpg?v=1788694129","url":"https:\/\/voomisupply.com\/products\/hertel-k008456as-3-8-24-unf-plug-hand-tap-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
