Unlike cutting taps, this forming tap displaces material rather than cutting it, producing stronger, work-hardened threads with no chips to evacuate. It carries a modified bottoming chamfer with 2.5 to 3 chamfered threads, allowing thread forming close to the bottom of blind holes. The D6 thread limit holds a 3B class of fit. Coolant-through capability supports higher feed rates in production environments. Licensed machinists and toolroom professionals are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for both blind hole and through-hole threading applications across a broad range of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium. The modified bottoming chamfer makes it particularly effective in shallow blind hole conditions where a standard plug or spiral chamfer would leave insufficient full threads. It fits production machining, tool and die, and maintenance and repair operations where thread quality and hole strength are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) design work-hardens the thread form for greater fatigue resistance\u003c\/li\u003e\n\u003cli\u003eCobalt HSS base material provides elevated heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive and high-strength materials\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed production tapping with internal coolant delivery\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2.5 to 3 threads) enables threading close to blind hole floors\u003c\/li\u003e\n\u003cli\u003eD6 thread limit maintains 3B class of fit for standard metric fastener compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for M12x1.75 Metric Coarse thread forming in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium workpieces in blind hole and through-hole configurations.

Power down and secure the workpiece before tool changes. Use the correct tap drill size for the M12x1.75 thread form pitch to achieve the required thread engagement without overloading the tap. Coolant-through setups require confirmed coolant pressure and flow before cycling to prevent tool breakage in harder materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2.5 to 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: 4.331 inches (110 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.669 inches (17 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.933 inches (49.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches (9.32 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.276 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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum; Cast Aluminum; Carbon Steel; Alloy Steel; Die Steel; Hardened Steel; Stainless Steel; High-Nickel Alloy; Titanium\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: 16150 (EXOPRO XPF-OIL)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.137 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1615012756\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732911718706,"sku":"1615012756","price":226.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/279692742061a87d06b545b80fafa0bf_a47d4da9-c03a-4a6f-b38a-11b107410489.jpg?v=1788748782","url":"https:\/\/voomisupply.com\/products\/osg-1615012756-thread-forming-tap-m12x1-75-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
