Built from High-Speed Steel-E with a Titanium Nitride (TiN) coating, this right-hand tap generates threads through material displacement rather than cutting, producing stronger threads with no chips to clear. It measures 1.7717 inches overall length with a 0.2756-inch thread length and a 0.1102-inch shank diameter. Machinists and toolroom technicians install this tap in CNC machining centers, drill presses, or tapping machines for production and repair threading operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for both blind hole and through-hole threading applications across a wide range of materials including steel, stainless steel, cast iron, non-ferrous metals, and superalloys. The TC410 Advance series designation indicates a general-purpose forming tap optimized for small-diameter unified threads in tight-tolerance work. With a tapping depth of 0.4724 inches and a flute-by-diameter ratio of 3.5xD, it is well-matched to high-volume production environments where thread quality and tool life are priorities. Coolant-through capability is not supported on this configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design displaces material to create stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and improves wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eHigh-Speed Steel-E construction provides toughness and performance in steel, stainless steel, cast iron, non-ferrous metals, and superalloys\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2-3 threads) allows threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e3 oil grooves support lubrication flow during the forming process\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 2BX class of fit for unified external thread mating parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style tooling solution for 2-56 UNC thread forming applications in blind and through-hole configurations across steel, stainless steel, cast iron, non-ferrous metal, and superalloy workpieces, consistent with material application codes P, M, K, N, and S.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps must be used with an appropriate tapping fluid or cutting oil rated for the workpiece material to prevent galling, especially in stainless steel and superalloys. Ensure the tap holder provides proper float to compensate for pitch synchronization in rigid tapping setups. Power down and secure the workpiece before manual tap changes. Follow shop-specific speeds and feeds for the 2-56 diameter class, as overfeeding a forming tap at this diameter can cause breakage.\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\u003eClass of Fit\u003c\/strong\u003e: 2BX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming (Semi-Bottoming)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2-3P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.7717 inches (45 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.2756 inches (7 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.4724 inches (12 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1102 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.0827 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E (WY80AD grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TC410 Advance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: WALTER-PROTOTYP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7427633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67905975288114,"sku":"7427633","price":115.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bc28d63690a11b5e13279517549e08f.jpg?v=1791161490","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-7427633-thread-forming-tap-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
