Manufactured from high-speed steel (HSS) with an oxide finish, this 4-flute straight-flute tap handles the rigors of production threading in ferrous materials. It carries a Class 3B fit and an H3 thread limit, making it appropriate for applications where close-tolerance internal threads are required. Overall length is 3.375 inches, with a thread length of 1.656 inches. Licensed machinists, tool and die makers, and maintenance technicians use this tap for hand-driven or low-speed machine tapping in a range of industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading cast iron, ductile iron, and steel workpieces where a bottoming chamfer is needed to cut threads as close to the bottom of a hole as possible. The straight flute geometry makes it appropriate for through-holes and shallow blind holes in these materials. The 1\/2-13 UNC thread form is a common fastener size across general manufacturing, structural fabrication, and maintenance repair operations, making this tap a frequently needed tool in any industrial shop environment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish improves lubricity and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design for stable cutting in cast iron, ductile iron, and steel\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit with H3 thread limit for close-tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, standard UNC thread form\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand tapping or low-speed machine tapping of 1\/2-13 UNC internal threads in cast iron, ductile iron, and steel.

Always ensure the pilot hole is drilled to the correct tap drill diameter for a 1\/2-13 UNC thread before beginning the tapping operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Never force the tap; back it off periodically to break chips and prevent tap breakage, especially in blind holes.\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\u003eChamfer Type\u003c\/strong\u003e: Bottoming\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight Flute\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: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches (3-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.656 inches (1-21\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Ductile Iron, Steel\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4131372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737826066738,"sku":"4131372","price":59.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8386b0c2a4ea2a8899e852f3dca4581.jpg?v=1788794006","url":"https:\/\/voomisupply.com\/products\/kennametal-4131372-hand-tap-1-2-13-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
