It is manufactured from powdered metal vanadium high speed steel and carries an AlCrTiN coating that improves heat and wear resistance during demanding tapping operations. The tap features a plug chamfer, 3-flute left-hand spiral geometry at a 10-degree helix angle, H3 thread limit, and a 3B class of fit. Overall length is 3.38 inches with a thread length of 0.77 inches and a tapping depth of 1.74 inches. It is intended for installation by machinist and toolroom trades in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading through or blind holes in high-temp alloy and nickel alloy workpieces where chip evacuation back toward the shank is required. The slow-spiral flute style is optimized for materials that produce stringy or tough chips. Typical applications include aerospace component machining, heat exchanger fabrication, and industrial equipment repair where 1\/2-13 UNC internal threads are required to a 3B tolerance class. Coolant-through is not supported by this tool; external cutting fluid application is recommended when conditions allow.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrTiN coating provides thermal resistance and extended tool life in high-temp alloy materials\u003c\/li\u003e\n  \u003cli\u003ePowdered metal vanadium high speed steel substrate for improved wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eLeft-hand slow-spiral flute geometry at 10-degree helix angle evacuates chips toward the shank\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) allows use in both through-hole and deeper blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 3B class of fit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, Series T690\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 1\/2-13 UNC internal threads in high-temperature alloy and nickel alloy workpieces.

Before tapping, ensure the drilled hole diameter matches the recommended tap drill size for a 1\/2-13 UNC thread at 3B class of fit. Secure the workpiece firmly and align the tap perpendicular to the hole surface to prevent tap breakage or thread misalignment. Use a suitable cutting fluid compatible with nickel and high-temp alloys, and clear chips frequently when working 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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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 Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Slow Spiral\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: 3.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.77 inches (19.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.74 inches (44.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches (9.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy, Nickel Alloy\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: T690\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 5705413\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755796857138,"sku":"5705413","price":147.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ef61a45cf0b184eb7aba20ab69824ec_547802e6-84c7-433d-8d31-4937d0aadd12.jpg?v=1788959810","url":"https:\/\/voomisupply.com\/products\/kennametal-5705413-spiral-flute-tap-1-2-13-unc-plug-3b","provider":"Voomi Supply","version":"1.0","type":"link"}
