It features a plug chamfer, two flutes, and a titanium nitride (TiN) coating over a high-speed steel (HSS) body. The spiral point geometry pushes chips forward ahead of the cut, making it well suited for through-hole tapping where chip evacuation is critical. The H2 thread limit holds tight tolerances for a 2B class of fit. Overall length is 1.813 inches with a thread length of 0.496 inches and a shank diameter of 0.141 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in production and maintenance machining environments where 3-48 UNC threads are required. It handles a broad range of workpiece materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. Typical applications include tapping threaded holes in small fastener locations, instrument panels, and precision assemblies. It is installed by machinists, tool-and-die technicians, and maintenance mechanics using a tap wrench, drill press, or CNC tapping cycle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point design pushes chips forward for efficient through-hole tapping\u003c\/li\u003e\n\u003cli\u003eTiN coating improves surface hardness and extends tool life across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness for interrupted and continuous cuts\u003c\/li\u003e\n\u003cli\u003eH2 thread limit delivers consistent 2B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for standard tapping operations\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup on manual and CNC equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 3-48 UNC through holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the workpiece and ensure the pilot hole diameter matches the recommended tap drill size for 3-48 UNC before starting. Power down or disengage the spindle before loading the tap into the holder. Use cutting fluid appropriate for the workpiece material to reduce heat and extend tap life. Follow shop safety procedures and applicable machining standards when operating tapping equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\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: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.496 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\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: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 1206005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744537280818,"sku":"1206005","price":34.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df15a8781a5f23a9ff55dfc4b54a1e95.jpg?v=1788857735","url":"https:\/\/voomisupply.com\/products\/osg-1206005-spiral-point-tap-3-48-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
