Built from high-speed steel with a bright, uncoated finish, this tap produces 1-8 UNC right-hand threads to a Class 2B fit with an H6 thread limit. It carries four flutes for efficient chip evacuation and controlled cutting performance. With an overall length of 5.13 inches and a thread length of 2.5 inches, it is sized for standard production and repair threading operations in job shops, maintenance facilities, and manufacturing environments. Licensed machinists and toolroom technicians are the primary users of this tap.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading cast iron and non-ferrous metals, making it a practical choice for both production threading and field repair work. The plug chamfer style — typically 3 to 5 lead threads — allows the tap to start easily in through-holes and blind holes with adequate clearance. It is part of the Kennametal Series 5305 and 5303 product lines. The straight-flute geometry is best applied in shorter-chipping materials such as cast iron, brass, and bronze, where chip packing is not a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC right-hand thread form, Class 2B fit, H6 thread limit for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a broad range of metal-cutting conditions\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (approx. 3-5 lead threads) enables easy starting in through-holes and open blind holes\u003c\/li\u003e\n  \u003cli\u003eFour straight flutes support controlled chip flow in short-chipping materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — suitable for use with cutting fluid for extended tool life\u003c\/li\u003e\n  \u003cli\u003e0.8-inch shank diameter provides solid grip in standard tap holders and T-handle wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading cast iron and non-ferrous metals.

Always apply an appropriate cutting fluid for the workpiece material before threading to reduce friction and extend tool life. Ensure the tap is started square to the hole to prevent thread runout or tap breakage. Do not force the tap through hard obstructions — back off periodically to break and clear chips 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: 1-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\u003eOverall Length\u003c\/strong\u003e: 5.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.8 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  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5305, 5303\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: 4131272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748649271602,"sku":"4131272","price":266.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80d22fa3bc6f531ed34b1277e2101ea0.jpg?v=1788896191","url":"https:\/\/voomisupply.com\/products\/kennametal-4131272-hand-tap-1-8-unc-plug-rh-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
