Ground from vanadium high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, this tap delivers extended tool life in demanding production environments. It features 3 right-hand spiral flutes with a 15-degree helix angle that efficiently evacuate chips upward during through-hole and blind-hole applications. The bottoming chamfer allows threading close to the bottom of a blind bore. Overall length is 2 inches (100 mm). Coolant-through capability is supported, making it suitable for high-volume CNC tapping operations. Machinists and tool-room professionals working in job shops or production settings are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading 1\/2-20 UNF holes in alloy steel, aluminum, carbon steel, cast iron, and die steel. The bottoming chamfer style makes it the right choice when thread depth must extend to the bottom of a blind hole, often used as the finishing tap after a plug or taper tap has started the thread. The 2B class of fit is the standard tolerance for general-purpose UNF fastener applications. Coolant-through design supports both flood and high-pressure coolant delivery in CNC machining centers and tapping heads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF thread form with 2B class of fit for standard fastener tolerance\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the bottom of blind bores\u003c\/li\u003e\n  \u003cli\u003e3 right-hand spiral flutes with 15-degree helix angle for upward chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces friction for longer tool life\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction withstands heat and abrasion in production cutting\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with CNC tapping and high-pressure coolant systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in alloy steel, aluminum, carbon steel, cast iron, and die steel workpieces requiring 1\/2-20 UNF internal threads.

Always ensure the tap is properly aligned with the drilled pilot hole before engagement to avoid cross-threading or breakage. Power down and lock out any machine before installing or removing the tap from the holder. Follow the tool manufacturer and machine OEM guidelines for RPM, feed rate, and coolant delivery appropriate to the 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: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.614 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches (100 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\u003eNeck Length\u003c\/strong\u003e: 0.685 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Cast Iron, Die Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 13013\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.105 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: 1301301408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742720852274,"sku":"1301301408","price":162.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e9c2091fc79000bf6f2712fdfcb4a48_d041b362-f855-44ef-93d7-b0e1bd946f23.jpg?v=1788839068","url":"https:\/\/voomisupply.com\/products\/osg-1301301408-spiral-flute-tap-1-2-20-unf-bottoming-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
