Built from high-speed steel with a bright, uncoated finish, this tap cuts a 1\/2-13 UNC right-hand thread to a 3B class of fit with an H3 thread limit. The plug chamfer, with its 3 to 5 lead threads, makes it suitable for starting in a hole and progressing through material in a controlled manner. At 3.375 inches overall length, it fits standard tap handles and machine setups used in production and maintenance work. Machinists, toolmakers, and maintenance mechanics are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in general metalworking, maintenance, repair, and manufacturing operations where a 1\/2-13 UNC internal thread is required. The straight flute geometry works well in through-holes in materials that produce short, brittle chips, such as cast iron, brass, and some aluminum alloys. The plug chamfer allows the tap to be used as a starter tap or as the sole tap in through-hole applications. It is suited for both hand tapping and low-speed machine tapping on drill presses or CNC equipment with rigid tapping capability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form cuts standard Unified National Coarse internal threads\u003c\/li\u003e\n  \u003cli\u003e3B class of fit with H3 thread limit ensures dimensional compliance for standard fastener assemblies\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and regrindability for shop use\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3 to 5 lead threads starts easily and works in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight flute design clears chips downward or through the hole, best suited for brittle chip-forming materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows easy visual inspection of the tap during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production tap for any application requiring a 1\/2-13 UNC, 3B class of fit internal thread in metalworking or maintenance operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or maintenance mechanic following standard tapping procedures. Always drill the correct tap drill size for a 1\/2-13 UNC thread before tapping and ensure the workpiece is securely fixtured. When hand tapping, use a properly sized tap wrench and apply cutting fluid appropriate for the workpiece material. When machine tapping, confirm spindle speed and feed rate are set for the tap diameter and material to avoid tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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 Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 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: 1.16 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: K008510AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727130165554,"sku":"K008510AS","price":46.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5836b5e21f704b9eb628e7005363d329.jpg?v=1788673815","url":"https:\/\/voomisupply.com\/products\/hertel-k008510as-straight-flute-tap-1-2-13-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
