It produces a 1\/4-20 UNC thread profile with a right-hand thread direction and a plug chamfer for general-purpose starting. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this tap is built for consistent performance in production and maintenance environments. The 3-flute design pushes chips forward ahead of the cutting zone, keeping the flutes clear during the threading operation. The H3 thread limit holds tight tolerances for a Class 3B fit. Overall length is 2.5 inches with a 1.0 inch thread length, making it suitable for standard-depth through-hole work.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for threading cast iron, ductile iron, and non-ferrous metals in both shop and field settings. It is well-suited for maintenance, repair, and fabrication operations where 1\/4-20 UNC threads are required in through-holes. The spiral point geometry moves chips ahead of the tap rather than packing them in the flutes, which reduces the risk of tap breakage in production-speed applications. Machinists and maintenance technicians working on machinery, fixtures, and structural assemblies will find this a reliable general-purpose threading tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eSpiral point design pushes chips forward for cleaner through-hole threading\u003c\/li\u003e\n  \u003cli\u003e3 flutes provide a balance of chip clearance and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for Class 3B fit tolerance control\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows use in both starting and through-hole continuation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated HSS construction suitable for cast iron, ductile iron, and non-ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in cast iron, ductile iron, and non-ferrous metals.

Always ensure the workpiece is securely fixtured and the drill hole is cleared of debris before tapping. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Reverse the tap periodically when hand-tapping to break chips and prevent binding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.0 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5301\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Ductile Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 1542020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729313857842,"sku":"1542020","price":37.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ea4a30e8a1ebe705c9dc5fdb135c105.jpg?v=1788702784","url":"https:\/\/voomisupply.com\/products\/kennametal-1542020-spiral-point-tap-1-4-20-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
