It features a modified bottoming chamfer, a 2B class of fit, and a TICN (titanium carbonitride) coating over a powdered metal substrate. The 15-degree right-hand helix flutes evacuate chips up and out of the hole, making this tap well suited for blind-hole tapping in tough materials. Overall length is 3.594 inches with a shank diameter of 0.429 inches. The H5 thread limit holds tight tolerances required for precision threaded assemblies. Licensed machinists, toolroom technicians, and production floor operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. It performs in both manual tapping operations and CNC machining centers where controlled spiral-flute action is preferred over straight-flute designs. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard taper or plug chamfer, which is critical in close-tolerance fixture and component work. No coolant-through capability is present, so external cutting fluid or flood coolant at the spindle is the standard approach for heat management in hard materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form with 2B class of fit for standard fastener tolerance applications\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading near the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eTICN coating increases surface hardness and reduces built-up edge in abrasive and high-alloy materials\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides uniform grain structure and improved wear resistance over conventional HSS\u003c\/li\u003e\n  \u003cli\u003e15-degree right-hand spiral flute promotes upward chip evacuation in blind-hole tapping\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit suits close-tolerance 2B fit requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. Part of the OSG EXOTAP Series 313, designed as an OEM-style replacement or direct substitute for spiral flute taps in the 1\/2-13 UNC modified bottoming category.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician using a properly sized tap holder or CNC rigid-tapping setup. Power down and secure the workpiece before tool changes. Apply appropriate cutting fluid for the workpiece material, as this tap does not include coolant-through capability. Follow shop-standard speeds and feeds for spiral flute taps in powdered metal tooling; do not exceed recommended surface footage for the material being tapped.\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\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\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.594 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.614 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.972 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.429 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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOTAP 313\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.105 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: 1704908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728486793522,"sku":"1704908","price":110.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a919ca79e01f031cd8f7f813828b12f_c9e007cd-70b3-4fc5-a38f-eda231d20c9e.jpg?v=1788691982","url":"https:\/\/voomisupply.com\/products\/osg-1704908-spiral-flute-tap-1-2-13-unc-ticn-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
