Built from high speed steel (HSS) with a bright, uncoated finish, this plug chamfer tap is suited for general-purpose tapping in a range of workpiece materials. The 3-flute spiral point design pushes chips forward ahead of the cut, keeping the flutes clear and reducing the risk of chip packing in production or repair environments. Thread limit is H4, and the class of fit is 3B, making it appropriate for standard-tolerance UNC fastener applications. Machinists, toolmakers, and maintenance technicians use this tap by hand or in a machine tapping setup.\u003c\/p\u003e\u003cp\u003eThis tap is intended for right-hand 1-8 UNC through-hole threading in metalworking and fabrication settings. The plug chamfer — typically 3 to 5 threads of taper — allows the tap to start easily in a pre-drilled hole and is the standard choice for through-hole work on machine tools, drill presses, and tapping arms. With a thread length of 2.5 inches, it covers a wide range of material thicknesses without tool changes. It is a common choice in job shops, maintenance departments, and manufacturing cells where 1-inch UNC fastener threads are routinely cut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-8 UNC thread form, right-hand cut, 3B class of fit\u003c\/li\u003e\n\u003cli\u003e3-flute spiral point geometry pushes chips forward for cleaner through-hole threading\u003c\/li\u003e\n\u003cli\u003eH4 thread limit for standard-tolerance UNC applications\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles general-purpose threading in steel, aluminum, and similar materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coolant-through required\u003c\/li\u003e\n\u003cli\u003e2.5-inch thread length accommodates a wide range of material thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock tap for 1-8 UNC right-hand through-hole tapping operations. Compatible with standard 1-inch tap holders and machine tapping chucks that accept taps of this shank size and thread specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolmaker familiar with tapping operations and proper cutting speeds for HSS tooling. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 1-8 UNC before starting. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. When using in a machine setup, verify the tapping spindle is aligned to avoid tap breakage from side loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\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: H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel (HSS)\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: MSC-04559084\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716513268018,"sku":"MSC-04559084","price":74.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c1d4769f9dda637c8b207f5b833dda0.jpg?v=1788527148","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04559084-spiral-point-tap-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
