Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended wear resistance and reduced friction during tapping operations. The plug chamfer (3-5 threads) eases starting in through-holes and blind holes where some lead-in is acceptable. With a 4-flute configuration and right-hand thread direction, this tap is suited for stable chip management in medium-to-hard materials. Overall length is 4.25 inches with a 2-inch thread length and a 0.59-inch shank diameter. It is typically used by machinists and maintenance technicians working in production or repair environments.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading operations in cast iron, stainless steel, and steel workpieces. It is used in machine shops, manufacturing facilities, and industrial maintenance settings where 3\/4-16 UNF threads are required. The TiN coating makes it a practical choice when working with abrasive or work-hardening materials that accelerate tool wear on uncoated taps. The 3B class of fit and H3 thread limit produce threads within standard tolerances for most mechanical fastener applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-16 UNF right-hand thread form for standard unified fine-pitch threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3-5 lead threads for use in through-holes and accessible blind holes\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life when tapping cast iron, stainless steel, and alloy steel\u003c\/li\u003e\n\u003cli\u003e4-flute straight flute geometry provides stable cutting and chip clearance\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 3B class of fit for standard tolerance threaded connections\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles intermittent cutting loads in hand or machine tapping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for applications requiring 3\/4-16 UNF internal threads in cast iron, stainless steel, and steel workpieces per the class 3B fit standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by licensed machinists or qualified maintenance technicians using a tap wrench or machine tapping setup. Secure the workpiece before starting and ensure the tap is aligned square to the hole to prevent tap breakage or cross-threading. Apply appropriate cutting fluid for the material being tapped, particularly with stainless steel, to reduce galling and heat buildup. Never force a tap that has stalled or seized — back out and clear chips before continuing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4130689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733317812530,"sku":"4130689","price":181.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2529e0d24ca99a15b2a63373889cd7e5.jpg?v=1788754129","url":"https:\/\/voomisupply.com\/products\/kennametal-4130689-hand-tap-3-4-16-unf-plug-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
