Built from high-speed steel with a bright (uncoated) finish, this plug-chamfer tap is suited for through-hole and blind-hole threading where a standard entry chamfer is appropriate. It carries a Class 2B fit tolerance and an H3 thread limit, providing reliable dimensional consistency for standard fastener assemblies. The tap measures 2.38 inches overall length with a 0.875-inch thread length and a shank diameter of 0.194 inches. It runs four flutes in a straight configuration, making it compatible with hand tapping operations and compatible with standard tap handles and tapping machines.\u003c\/p\u003e\u003cp\u003eThis tap is used in job shops, maintenance facilities, and production environments where 10-32 UNF threads are required in cast iron and non-ferrous metals such as aluminum, brass, and copper. The plug chamfer — typically 3 to 5 threads of lead — makes it the most common tap style for starting threads in through-holes or continuing after a taper tap in blind holes. It belongs to KENNAMETAL Series 5305 and 5303 and is sold individually in single-piece packaging.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-32 UNF thread form, Class 2B fit, H3 thread limit for standard tolerance control\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3 to 5 thread lead) for versatile through-hole and blind-hole use\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across cast iron and non-ferrous metal applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup concerns in tight-tolerance threading\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute design suited for hand tapping and machine tapping operations\u003c\/li\u003e\n\u003cli\u003e2.38-inch OAL with 0.875-inch thread length and 0.194-inch shank diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 10-32 UNF internal threads in cast iron and non-ferrous metals.

Apply cutting fluid suitable for the workpiece material — especially important when tapping non-ferrous metals to reduce galling and extend tap life. Back the tap off periodically to break chips and prevent tap binding. Never force a tap against resistance; doing so risks tap breakage and thread damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 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\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal\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: 5305, 5303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1542079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733629468978,"sku":"1542079","price":26.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5dee7f44d84aa895c59a30d8c77a360.jpg?v=1788757123","url":"https:\/\/voomisupply.com\/products\/kennametal-1542079-hand-tap-10-32-unf-plug-hss-bright","provider":"Voomi Supply","version":"1.0","type":"link"}
