Built from cobalt high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, this tap is engineered for demanding materials including stainless steel, titanium, high-nickel alloys, hardened steel, and aluminum. It features a modified bottoming chamfer with 2.5 to 3 chamfered threads, making it well suited for blind hole and through-hole threading where thread engagement close to the bottom of the bore is required. The H3 thread limit ensures consistent pitch diameter control. Part of the OSG EXOPRO XPF Series 16250, this tap is a right-hand, non-coolant-through design with an overall length of 2.2047 inches (56 mm).\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in metalworking and machining environments where cold-forming rather than cutting produces threads by displacing material. It is appropriate for blind hole and through-hole threading operations on ferrous and non-ferrous metals across a broad hardness range. Typical installations include production machining, tool and die work, and aerospace or industrial component manufacturing where thread quality and tap life in difficult materials are critical. A licensed machinist or CNC operator is the expected end user.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (cold-form) design eliminates chips, reducing risk of chip packing in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt HSS construction provides elevated heat and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and lubricity for extended tap life\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2.5-3P) allows threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e3B class of fit with H3 thread limit for precise pitch diameter control\u003c\/li\u003e\n\u003cli\u003eRated for aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole and through-hole threading in materials coded P, M, N, and H, including aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium.

Apply a suitable tapping fluid or cutting oil rated for the workpiece material, particularly when working in stainless steel, titanium, or high-nickel alloys. Power down and secure the workpiece before tap engagement in manual setups. Follow applicable shop safety standards and machine tool manufacturer guidelines when operating CNC or manual tapping equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: H3\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: 2.5-3P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.7210 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.2047 inches (56 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Hardened Steel, Carbon Steel, Alloy Steel, Die Steel, Stainless Steel, High-Nickel Alloy, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOPRO XPF 16250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 1625005403\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737067258162,"sku":"1625005403","price":92.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_4b8fd9d2-faa2-4810-8e19-99a31bb00cab.jpg?v=1788783835","url":"https:\/\/voomisupply.com\/products\/osg-1625005403-thread-forming-tap-5-40-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
