Manufactured from high-speed steel with a TiCN coating, it delivers improved wear resistance and heat reduction compared to uncoated HSS tooling. The plug chamfer configuration provides a gradual thread lead-in, making it well suited for through-hole tapping applications. With a 50-degree helix angle and 3 right-hand spiral flutes, the tool efficiently evacuates chips upward out of the hole, reducing the risk of chip packing. It carries an H3 thread limit and a 3B class of fit, meeting standard tolerance requirements for most general-purpose threaded connections. Overall length is 3-3\/8 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is designed for tapping through holes in a variety of materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The spiral flute geometry makes it especially effective in materials that produce long, stringy chips. It is a practical choice for production machining, job-shop work, and maintenance applications where 1\/2-13 UNC threads are required. The TiCN coating extends tool life in abrasive materials and contributes to cleaner thread form across higher-volume runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form with 3B class of fit and H3 thread limit\u003c\/li\u003e\n  \u003cli\u003e3 right-hand spiral flutes at 50-degree helix angle for upward chip evacuation in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for increased surface hardness and wear resistance versus uncoated HSS\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for gradual thread engagement and lead-in\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction suitable for aluminum, cast iron, and carbon steel grades\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement — compatible with flood or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for tapping 1\/2-13 UNC through holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.

Ensure the pilot hole is drilled to the correct tap drill diameter for 1\/2-13 UNC before tapping. Apply a suitable cutting fluid or tapping compound for the workpiece material to reduce friction and extend tool life. Inspect threads with a 3B class GO\/NO-GO gauge after tapping to confirm dimensional compliance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\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: 3B\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eThreads per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.96 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: 0.783 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: 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: 107\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: 1432008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731023102258,"sku":"1432008","price":109.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72aa2bd378ba477ae3a37c8337744ff6.jpg?v=1788725993","url":"https:\/\/voomisupply.com\/products\/osg-1432008-spiral-flute-tap-1-2-13-unc-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
