It produces 10-32 UNF threads to a 2BX class of fit using a modified bottoming chamfer with 2-3 chamfered threads. Manufactured from High-Speed Steel-E and coated with Titanium Nitride, the tap offers wear resistance and reduced friction during the forming process. Overall length is 2.756 inches, with a tapping depth of 0.984 inches and a thread length of 0.512 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for machine shops, production facilities, and field maintenance environments where precise internal thread forming is required. The 10-32 UNF thread size is common in electrical enclosures, instrumentation panels, and light mechanical assemblies. The semi-bottoming chamfer makes it usable in both shallow blind holes and through-hole setups. Material application codes P, M, K, N, and S indicate suitability across steel, stainless steel, cast iron, non-ferrous materials, and heat-resistant alloys. Machinists, tool-and-die professionals, and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, producing stronger threads with no chip generation\u003c\/li\u003e\n  \u003cli\u003eTitanium Nitride coating reduces friction and extends tap life in production runs\u003c\/li\u003e\n  \u003cli\u003eHigh-Speed Steel-E construction with material grade WY80AD for toughness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer with 2-3 chamfered threads for blind-hole and through-hole use\u003c\/li\u003e\n  \u003cli\u003eFive oil grooves support lubrication distribution during the forming process\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 3.5xD flute-by-diameter ratio for chip clearance considerations in thread forming\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production tap for applications requiring 10-32 UNF internal threads in steel, stainless steel, cast iron, non-ferrous, and heat-resistant alloy 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 require a properly sized forming tap drill hole, which differs from cutting tap drill sizes  -  consult the appropriate forming tap drill chart for the 10-32 UNF specification before drilling. Use a suitable tapping fluid or cutting oil to aid the forming process and protect the coating. Always secure the workpiece and set tapping machine speed to the recommended surface footage for High-Speed Steel taps on the target material. Discontinue use if the tap shows signs of galling or excessive torque buildup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32 UNF\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: 2BX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2-3P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.756 inches (70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.512 inches (13 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.984 inches (25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.236 inches (6 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.193 inches (4.90 mm)\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: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: WY80AD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride\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: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application Codes\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TC410 Advance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 7427651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":68098090697010,"sku":"7427651","price":111.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bc28d63690a11b5e13279517549e08f_d3f3edb0-f678-4ef0-88db-aef46b08e922.jpg?v=1793277754","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-7427651-thread-forming-tap-10-32-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
