Built from powdered metal vanadium high speed steel and finished with an AlCrTiN coating, it handles the demanding cutting conditions those materials require. The plug chamfer provides a standard lead-in for through-hole and deeper blind-hole applications. With 3 left-hand spiral flutes at a 10-degree helix angle, the tool evacuates chips upward out of the hole — a key performance factor when working in gummy, work-hardening materials. Thread limit is H3 and class of fit is 3B.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for machining and production environments where high-temp alloy components require precise internal threads. Typical applications include aerospace, power generation, and industrial manufacturing where nickel-based alloys, Inconel, and similar S-grade materials are common. The AlCrTiN coating improves heat resistance and tool life at elevated cutting temperatures. The T690 series is engineered specifically for difficult-to-machine materials where standard HSS taps fail prematurely. Installation is performed on CNC machining centers or manual tapping fixtures. No coolant-through capability — external or flood coolant is the appropriate delivery method for this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF right-hand thread, 3B class of fit, H3 thread limit\u003c\/li\u003e\n  \u003cli\u003eAlCrTiN coating for elevated heat and wear resistance in high-temp alloy cutting\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral flutes with 10-degree helix angle for upward chip evacuation\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for versatile through-hole and blind-hole threading\u003c\/li\u003e\n  \u003cli\u003ePowdered metal vanadium high speed steel substrate for toughness and edge retention\u003c\/li\u003e\n  \u003cli\u003eT690 series — engineered for primary workpiece material code S (high-temp and nickel alloys)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading high-temperature alloys and nickel alloys (workpiece material code S).

Ensure the spindle and workpiece are fully secured before engaging the tap. Use appropriate flood or external coolant — this tool does not support coolant-through delivery. Inspect the tap for wear or chipping before each use; work-hardening alloys accelerate edge degradation if feeds and speeds are not optimized for the material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003eChamfer\u003c\/strong\u003e: Plug\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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 (Code S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.600 inches (15.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches (9.68 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.680 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.280 inches (33.00 mm)\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: 5705422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737793265970,"sku":"5705422","price":96.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ef61a45cf0b184eb7aba20ab69824ec_87849308-bd49-47c8-9706-129d3cc6bcd0.jpg?v=1788793619","url":"https:\/\/voomisupply.com\/products\/kennametal-5705422-spiral-flute-tap-3-8-24-unf-plug-3b","provider":"Voomi Supply","version":"1.0","type":"link"}
