Unlike cutting taps, thread forming taps cold-form the thread profile by displacing material rather than cutting it, producing stronger threads with no chips to clear. This tap is sized for M5x0.8 metric threads and measures 2.375 inches overall length with a thread length of 0.875 inches. The TiN coating increases surface hardness and reduces friction during forming. It is used by machinists, tool-and-die makers, and maintenance technicians working on blind hole threading applications where chip evacuation would otherwise be a concern.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading in metric M5x0.8 applications. The bottoming chamfer with 1 to 2 chamfered threads allows threads to be formed close to the bottom of a blind hole, making it well suited for precision machined components, fixture work, and production environments where full thread depth is required. The right-hand thread direction matches standard metric fastener orientation. A D7 thread limit designates the tolerance class for the formed thread, appropriate for standard metric fit requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting, eliminating chips in blind holes\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 1 to 2 chamfered threads for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness and wear resistance across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eTitanium nitride coating reduces friction and extends tap service life\u003c\/li\u003e\n\u003cli\u003eD7 thread limit for standard metric tolerance fit\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard metric fastener orientation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading applications requiring M5x0.8 metric right-hand threads with a D7 thread limit tolerance class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a properly sized forming tap drill hole, which is larger than a standard cutting tap drill size for the same thread — consult a thread forming drill chart for the correct hole diameter before use. Secure the workpiece and use a calibrated tap handle or machine spindle aligned to the hole axis to avoid tap breakage. Apply appropriate tapping fluid or cutting oil for the workpiece material. Power down and de-energize any machine tool before changing or installing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M5x0.8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 2P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches (60.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches (4.93 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.152 inches (3.86 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K010455AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727963849010,"sku":"K010455AS25","price":28.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43a62bec66451727374be01e71723a4b.jpg?v=1788685058","url":"https:\/\/voomisupply.com\/products\/hertel-k010455as25-thread-forming-tap-m5x0-8-bottoming-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
