It uses a modified bottoming chamfer with 2.5 to 3 chamfered threads, making it suited for blind hole and through-hole threading applications where chip evacuation is a concern. Manufactured from cobalt high-speed steel and finished with a TiCN coating, this tap handles a wide range of workpiece materials including aluminum, carbon steel, alloy steel, stainless steel, hardened steel, high-nickel alloy, and titanium. It carries an H3 thread limit and a 2B class of fit. Licensed machinists and toolroom technicians use this tap in production and maintenance environments where thread quality and tool life are critical.\u003c\/p\u003e\n\u003cp\u003eThis tap is part of the OSG EXOPRO XPF Series 16250. It is suited for blind hole and through-hole threading in materials coded P, M, N, and H, covering carbon and alloy steels, stainless steels, high-nickel alloys, and non-ferrous materials such as aluminum and cast aluminum. The modified bottoming chamfer allows threading closer to the bottom of a blind hole compared to standard taper or plug chamfers, which is useful in tight-tolerance fixturing and close-tolerance assembly work across aerospace, automotive, and general machining applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, eliminating chips in blind holes\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides heat and wear resistance in demanding machining operations\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2.5 to 3 threads) enables threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 2B class of fit for standard tolerance threading requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping heads and CNC rigid tapping cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for 3-48 UNC blind hole and through-hole threading in aluminum, cast aluminum, hardened steel, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium workpieces.

Secure the workpiece and use appropriate tapping fluid for the workpiece material to prevent galling, particularly in stainless steel and high-nickel alloys. Power down CNC equipment or tapping machines before changing tooling and confirm holder runout is within acceptable limits. This tap is intended for use by qualified machinists familiar with tapping speeds and feeds for the applicable workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\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: 2B\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 to 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 48\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: 0.385 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.424 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9685 inches (50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 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\u003eSeries\u003c\/strong\u003e: EXOPRO XPF 16250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 1625003483\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746501951794,"sku":"1625003483","price":97.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_1a01ff5c-7d74-46ed-9e49-a8b5b45da03e.jpg?v=1788870864","url":"https:\/\/voomisupply.com\/products\/osg-1625003483-thread-forming-tap-3-48-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
