Built from powdered metal high-speed steel (PMT15 grade) and coated with TiCN for enhanced wear resistance and lubricity, this tap cuts 12-24 UNC threads to a 2B class of fit with an H3 thread limit. It features 3 flutes and a plug chamfer, making it well suited for through-hole tapping. The overall length is 3.15 inches (80 mm) with a thread length of 0.496 inches (12.70 mm) and a shank diameter of 0.220 inches. Machinists and toolroom technicians install this tap in CNC machining centers, knee mills, and drill presses where consistent thread quality and tool life are critical.\u003c\/p\u003e\u003cp\u003eThis tap is part of OSG Series 16515, positioned as a high-performance spiral point tool for production and job-shop environments. It is not coolant-through and does not produce an interrupted thread. The 2B class of fit meets standard commercial threading tolerances for general fastener assembly. Non-oversize construction keeps thread geometry within H3 limits. Typical applications include tapping through holes in machined components where chip evacuation ahead of the tap is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating improves surface hardness and reduces built-up edge during cutting\u003c\/li\u003e\n\u003cli\u003ePowdered metal HSS (PMT15 grade) provides tighter grain structure and better wear resistance than conventional HSS\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3 flutes drives chips forward through the hole for clean through-hole tapping\u003c\/li\u003e\n\u003cli\u003eH3 thread limit and 2B class of fit meet standard commercial threading tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual tapping setups\u003c\/li\u003e\n\u003cli\u003eCompact 3.15-inch overall length suits both manual and machine tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 12-24 UNC through holes in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the workpiece firmly and ensure the spindle is properly aligned with the hole axis before beginning the tapping cycle. Use an appropriate tapping fluid or cutting oil matched to the workpiece material to extend tool life and improve thread finish. Inspect the tap for wear or chipping before each use and replace if cutting edges show degradation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-24 UNC\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: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal HSS (PMT15)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.15 inches (80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.496 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.220 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 1651501408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740504129842,"sku":"1651501408","price":53.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e13ecf30500ef6194b13b6389aa57b06_1f31bb29-2703-453b-abd4-6e9601520889.jpg?v=1788825474","url":"https:\/\/voomisupply.com\/products\/osg-1651501408-spiral-point-tap-12-24-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
