It features a modified bottoming chamfer, allowing the tap to cut closer to the bottom of a blind hole than a standard plug tap while still providing moderate lead-in guidance. Five flutes deliver rigidity and chip control in demanding materials. The TiCN coating increases surface hardness and lubricity, reducing heat buildup and extending tool life in tough ferrous alloys. The powdered metal substrate provides a finer grain structure than standard HSS, contributing to edge retention under high-load threading conditions.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for machine threading operations in CNC machining centers, drill presses, and tapping machines where consistent thread quality in hardened or alloy steel is required. The 2B class of fit and H5 thread limit make it appropriate for standard-tolerance fastener applications in industrial, toolroom, and maintenance manufacturing environments. It is installed and operated by machinists and tool-and-die trades in production and job-shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eModified bottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for improved wear resistance and reduced friction in hardened and alloy steels\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction for enhanced edge retention over standard HSS\u003c\/li\u003e\n  \u003cli\u003e5-flute design provides rigidity and chip management in tough materials\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit and 2B class of fit for standard-tolerance UNC thread production\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for machine threading of hardened steel and alloy steel workpieces requiring 1\/2-13 UNC internal threads to a 2B class of fit.

Ensure the spindle is stopped and the machine is in a safe state before loading or changing the tap. Use appropriate tapping fluid or cutting oil rated for hardened and alloy steel to maximize tool life. Verify that the pre-drilled hole diameter matches the recommended tap drill size for 1\/2-13 UNC before beginning the threading operation.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-21\/32 inches (0.921 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches (3.375 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.933 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hardened Steel, Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 10051\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1005113008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729149034802,"sku":"1005113008","price":128.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1499c07407df9ed2bf2e3188f101e1c6.jpg?v=1788700891","url":"https:\/\/voomisupply.com\/products\/osg-1005113008-straight-flute-tap-1-2-13-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
