Unlike cutting taps, this tool displaces material rather than cutting it, producing stronger threads with no chips to clear. It carries a 4H class of fit with a D6 thread limit and features a modified bottoming chamfer of 2.5 to 3 threads, making it well suited for blind hole applications where thread engagement close to the bottom is required. The tap is manufactured from cobalt high-speed steel and finished with a TiCN coating to extend tool life under demanding conditions. Overall length is 3.937 inches (100 mm) with a thread length of 0.669 inches (17 mm).\u003c\/p\u003e\n\u003cp\u003eThis tap is used in production and maintenance machining environments where thread forming is preferred over thread cutting. It handles blind hole and through-hole threading operations across a broad material range including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium. It is part of the OSG EXOPRO XPF Series 16350, a line developed for high-performance forming applications in both job shop and production floor settings. Installation is performed by licensed machinists and toolroom professionals using standard tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2.5 to 3 threads) allows threading close to the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides elevated heat and wear resistance versus 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\u003e4H class of fit with D6 thread limit ensures consistent, on-tolerance thread geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; compatible with blind hole and through-hole applications\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through feature; suitable for use with flood or brush-applied cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium.

Power down and secure the workpiece before tool changes. Use an appropriate tapping fluid or cutting oil matched to the workpiece material to prevent galling, particularly in stainless steel and high-nickel alloys. Follow applicable shop safety and machine guarding practices during all tapping operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 4H\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 3 threads\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: 3.937 inches (100 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: 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\u003eSeries\u003c\/strong\u003e: 16350 (EXOPRO XPF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.125 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: 1635012156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754049405234,"sku":"1635012156","price":202.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_85c61aaa-0ed7-4074-9d02-fc97b619fef1.jpg?v=1788943166","url":"https:\/\/voomisupply.com\/products\/osg-1635012156-thread-forming-tap-m12x1-50-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
