Part of the EXOTAP VP-NRT series, it uses a cold-forming method that displaces material rather than cutting it, producing stronger threads with no chips to clear. The tap is manufactured from powdered metal high-speed steel (PM-HSS) and carries a TiCN coating for improved wear resistance and lubricity under load. With a modified bottoming chamfer of 2 to 2.5 threads, it is suited for threading close to the bottom of a blind hole. Licensed machinists and tool-and-die technicians are the primary installers in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. Its thread limit is D6 with a class of fit of 3B, making it appropriate for standard metric fastener fits in precision assemblies. The modified bottoming chamfer allows threading deeper into blind holes where a standard plug or spiral point tap cannot reach. It is commonly used in automotive, aerospace, and general metalworking applications where thread integrity and surface finish are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material without cutting, producing chip-free blind hole threads\u003c\/li\u003e\n  \u003cli\u003ePowdered metal high-speed steel construction provides consistent grain structure and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5P) enables threading to near-bottom depth in blind holes\u003c\/li\u003e\n  \u003cli\u003eD6 thread limit and 3B class of fit for standard metric tolerance control\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping spindles and CNC tapping heads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Adequate tapping fluid or cutting oil must be applied to the workpiece before tapping to reduce heat and extend tool life. Ensure the spindle speed and feed rate are set per the tap manufacturer guidelines for the specific workpiece material before beginning the operation. Inspect the tap for wear or chipping before each use and replace if thread form shows signs of degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\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 to 2.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.3465 inches (85.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.8268 inches (21.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.9291 inches (49.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3670 inches (9.32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.2756 inches (6.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 11.11 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOTAP VP-NRT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 1415004408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740700803378,"sku":"1415004408","price":171.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/219f7caf0165a9628c75181e385a2c0c_d7de8543-d0af-474a-b47d-4a17c0885385.jpg?v=1788826823","url":"https:\/\/voomisupply.com\/products\/osg-1415004408-thread-forming-tap-m12x1-75-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
