Operating on a cold-forming principle, it displaces material rather than removing it, resulting in stronger threads with a burnished finish. Built from cobalt high-speed steel with a bright finish, this tap handles demanding materials where standard HSS taps fall short. It is configured as a plug chamfer with 4 to 4.5 chamfered threads, a 1\/4-20 UNC thread profile, and a right-hand thread direction. Overall length is 2.5 inches with a thread length of 0.594 inches and a tapping depth of 0.933 inches. Machinists and tool-and-die tradespeople install this tap in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 1400126900 is suited for through-hole threading applications across a broad range of workpiece materials. Its H2 thread limit makes it appropriate for general-purpose tolerance requirements. Rated material applications include alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel, covering the P and N material application codes. It is well matched to CNC tapping centers, manual drill presses, and hand-tapping setups where coolant-through tooling is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design produces chip-free internal threads for improved thread strength\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction increases heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 to 4.5 chamfered threads eases entry and reduces starting torque\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit suits standard tolerance through-hole applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 1\/4-20 UNC profile compatible with common inch-standard fasteners\u003c\/li\u003e\n  \u003cli\u003eBright finish baseline coating with no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Ensure the spindle speed and feed rate are matched to the 1\/4-20 pitch before engaging the tap. Secure the workpiece firmly and verify hole diameter is sized for the forming operation, as forming taps require a larger pilot hole than cutting taps. Power down or lock out the machine before changing or inspecting tooling.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: 0.594 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.933 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.191 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1400126900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743175115058,"sku":"1400126900","price":31.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52f3e0326fc340f2e93c596602760e58.jpg?v=1788843552","url":"https:\/\/voomisupply.com\/products\/osg-1400126900-thread-forming-tap-1-4-20-unc-plug-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
