It is machined from high-speed steel and coated with titanium nitride (TiN) for extended tool life and reduced friction at the cutting edge. The tap features 2 right-hand spiral flutes with a 50-degree helix angle, which pulls chips up and out of the hole during tapping — a critical advantage in blind-hole applications. At 2 inches overall length with an H3 thread limit, it is built to hold a 2B class of fit. Machinists, toolroom techs, and maintenance professionals use this tap in CNC and manual tapping operations.\u003c\/p\u003e\n\u003cp\u003eThe OSG 1412405 is rated for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. The plug chamfer — typically 3 to 5 threads of lead — makes it the standard choice for through-holes and for starting threads in a pre-drilled hole before a bottoming tap is used. It is well-suited to production environments where consistent thread quality and tool longevity are required across high-cycle operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-32 UNC right-hand thread, 2B class of fit with H3 thread limit for precise tolerance control\u003c\/li\u003e\n  \u003cli\u003e50-degree right-hand spiral flute geometry evacuates chips efficiently in blind and through-hole applications\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces built-up edge when cutting ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and regrindability for toolroom and production use\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides reliable thread lead-in for general-purpose tapping operations\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement — suitable for conventional flood coolant or tapping fluid setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 6-32 UNC threads; compatible with aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces.

Always drill the correct tap drill size for a 6-32 UNC thread before starting — an undersized hole will overload the tap and risk breakage. Apply appropriate tapping fluid or coolant for the workpiece material, and ensure the tap is aligned perpendicular to the workpiece surface. Do not reverse a broken tap with excessive force; use a tap extractor to avoid damaging the workpiece threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-32\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 50 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eFlute 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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.397 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\u003eNeck Length\u003c\/strong\u003e: 0.685 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\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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: 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: 1412405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734690988338,"sku":"1412405","price":47.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc6a41b3f34451527d1ea1df6a833152.jpg?v=1788764941","url":"https:\/\/voomisupply.com\/products\/osg-1412405-spiral-flute-tap-6-32-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
