Built from High-Speed Steel-E (HSS-E) and finished with a Titanium Nitride (TiN) coating, this tap uses a cold-forming process that displaces material rather than cutting it, producing stronger threads with no chips to evacuate. It carries a 6HX class of fit and features a modified bottoming chamfer with 2-3 chamfered threads for close-to-bottom thread production. Overall length is 3.15 inches (80 millimeters) with a tapping depth of 1.18 inches (30 millimeters). It is installed by machinists and tool-and-die professionals in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis tap suits blind-hole and through-hole threading operations in a range of workpiece materials. The TC410 Advance series is engineered for use in material application categories P (steel), M (stainless steel), K (cast iron), N (non-ferrous metals), and S (heat-resistant alloys). It is well suited for CNC machining centers and manual tapping operations where chip-free thread forming is required. The 3.5xD flute-to-diameter ratio and five oil grooves support lubrication distribution during the forming process, making it effective in both high-volume production runs and precision repair work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) process produces stronger threads by cold-working the material\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life across a broad range of materials\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer with 2-3 chamfered threads for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eFive oil grooves support consistent lubricant delivery during forming\u003c\/li\u003e\n\u003cli\u003e6HX class of fit for standard metric thread tolerance requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, suitable for standard CNC and manual tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for M6x1 right-hand metric thread forming in material groups P, M, K, N, and S, including steels, stainless steels, cast irons, non-ferrous metals, and heat-resistant superalloys in blind-hole and through-hole configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a forming-specific tap drill size  -  do not use a standard cut-tap drill chart, as forming taps require a larger pre-drilled hole diameter than cutting taps for the same thread size. Apply a threading fluid or cutting oil rated for the workpiece material before and during the tapping operation. Ensure the tap is properly aligned with the pre-drilled hole axis to prevent cross-threading or tool breakage. Always power down or de-energize the machine spindle before manually handling or changing taps.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M6x1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6HX\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2-3P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.15 inches (80 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.59 inches (15 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.18 inches (30 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.24 inches (6 millimeters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.19 inches (4.90 millimeters)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application Code\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: WY80AD\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: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7427627\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67910125650226,"sku":"7427627","price":115.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bc28d63690a11b5e13279517549e08f_f19a07ed-7ff5-49d7-bca4-a6937a468296.jpg?v=1791196105","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-7427627-m6x1-thread-forming-tap-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
