Built from high-speed steel (HSS) with a TiCN coating, it delivers improved wear resistance and reduced friction compared to uncoated taps. The plug chamfer style makes it suitable for through-hole applications where chips are pushed forward ahead of the cutting action. With 2 flutes and a right-hand thread direction, it is sized for precision threading in small-fastener work common to electronics, instrumentation, and light mechanical assemblies. Licensed machinists and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThe 1215608 is rated for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. Its compact geometry  -  1.75 inches overall length and a 7\/16 inch thread length  -  suits benchtop drill presses, CNC tapping centers, and hand-tapping operations where fine thread control is required in confined or small-bore workpieces. The H5 thread limit provides a controlled oversize allowance appropriate for plated or tight-tolerance threaded holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and extends tool life in abrasive and ferrous materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer advances chips forward, ideal for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eH5 thread limit provides controlled oversize for plated hole applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction balances toughness and cutting performance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute design for standard 2-56 UNC threading\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement  -  compatible with flood or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 2-56 UNC right-hand internal threads; compatible with aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTapping should be performed by a qualified machinist or maintenance technician using a calibrated tap wrench, tapping head, or CNC spindle set to the correct RPM for the material and tap size. Always apply appropriate cutting fluid or tapping compound before starting the thread. Secure the workpiece firmly and ensure the tap is aligned perpendicular to the hole to avoid tap breakage, which is a significant risk at the 2-56 size. Replace worn taps immediately  -  a broken tap in a small-diameter hole is difficult to remove without damaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\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 Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.441 inches (7\/16 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: 0.009 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: 1215608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743943098674,"sku":"1215608","price":45.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4400ac56e9d4c0bf96797b2e1667ef99.jpg?v=1788851687","url":"https:\/\/voomisupply.com\/products\/osg-1215608-spiral-point-tap-2-56-unc-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
