Built from high-speed steel with a bright, uncoated finish, this tap delivers consistent thread formation in production and maintenance applications. It features a plug chamfer for general-purpose through-hole and blind-hole threading, a 3B class of fit for standard tolerance internal threads, and an H3 thread limit for reliable dimensional control. Overall length is 2.5 inches, making it compatible with standard tap handles and machine tool holders used in machining and fabrication environments.\u003c\/p\u003e\u003cp\u003eThis tap is suited for use by machinists, maintenance technicians, and tool and die professionals working on light to medium threading operations. The 1\/4-18 UNS thread form is common in specialized fastener and pipe-adjacent applications where Unified National Special threads are required. The plug chamfer style makes it appropriate as a starting tap for most through-hole threading jobs and for finishing blind holes where adequate thread depth is achievable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-18 UNS thread form for Unified National Special thread applications\u003c\/li\u003e\n\u003cli\u003e4-flute straight flute design provides stable cutting action in a wide range of materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for general-purpose through-hole and standard blind-hole threading\u003c\/li\u003e\n\u003cli\u003e3B class of fit meets standard tolerance requirements for internal threaded components\u003c\/li\u003e\n\u003cli\u003eH3 thread limit provides consistent oversize control for reliable fit\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction offers durability in hand and machine tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard straight flute tap for use with compatible tap handles, tap wrenches, and CNC or manual machine tool holders sized for 1\/4-inch shank taps.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a tap handle, T-handle wrench, or machine tool holder appropriate for the shank diameter. Always ensure the workpiece is securely fixtured and the tap is properly aligned with the pilot hole before beginning the threading operation. Use appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Back the tap out periodically during hand tapping to break chips and prevent binding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4840195\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698378899762,"sku":"JY4840195","price":47.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb92d384dbfa5ad86035f9ccd2106a82.jpg?v=1788361973","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4840195-straight-flute-tap-1-4-18-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
