Built from bright, uncoated high-speed steel, it delivers clean thread formation in cast iron and non-ferrous metals without the added cost of a coated tool. The plug chamfer provides moderate lead-in, making it well suited for through-holes and blind holes with adequate depth clearance. Overall length is 1.75 inches, thread length is 0.438 inches, and the shank diameter is 0.141 inches. The 2-flute geometry keeps chip volume manageable in small-diameter work, which is critical at the number-2 thread size.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in low-volume or precision hand-tapping applications where a machine tap would be impractical or unnecessary. It targets Class 2B fit with an H2 thread limit, matching the tolerance requirements of most standard fastener assemblies in light manufacturing, instrument repair, and small-component fabrication. Applicable material types include cast iron and non-ferrous metals such as aluminum and brass. It belongs to Kennametal Series 5305 and 5303 and is sized for use in a standard tap handle appropriate for number-2 thread work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-56 UNC thread form, right-hand cut, Class 2B fit with H2 thread limit\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for moderate lead-in  -  works in through-holes and adequate-depth blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright, uncoated finish for cast iron and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003e2-flute straight-flute geometry manages chip load at small diameters\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.75 inches with a 0.438-inch thread length for tight clearance work\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement  -  suitable for hand tapping with cutting fluid applied manually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand tapping 2-56 UNC threads in cast iron and non-ferrous metal workpieces.

Secure the workpiece before starting; misalignment at number-2 thread sizes can break the tap without warning. Apply cutting fluid rated for the workpiece material before and during tapping. Inspect the tap for chipping or wear before each use  -  high-speed steel taps at small diameters are susceptible to brittle fracture if forced or cocked off-axis.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\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: H2\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: 2\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: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.438 inches (7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 4131466\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741058367794,"sku":"4131466","price":47.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e569c094ff6def1dee94ab2a43577b96.jpg?v=1788829137","url":"https:\/\/voomisupply.com\/products\/kennametal-4131466-hand-tap-2-56-unc-plug-rh-2b-h2-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
