Built from powdered metal (PMT15 grade) and finished with a TiCN coating, it delivers extended tool life in demanding production environments. The plug chamfer geometry guides the tap into the workpiece with a gradual thread engagement, and the 3-flute spiral point pushes chips forward ahead of the cutting zone, keeping the flutes clear during through-hole tapping. Overall length is 4.331 inches with a thread length of 0.921 inches. Licensed machinists and toolroom technicians are the primary users of this tap.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole tapping operations on machining centers, CNC lathes, drill presses, and manual tapping setups where a right-hand 1\/2-13 UNC thread to a 2B class of fit is required. It is engineered for use in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel. The H5 thread limit makes it appropriate for applications requiring consistent tolerance control across production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal (PMT15) construction for improved wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive materials including stainless and hardened steel\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral point pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides gradual thread engagement and accurate starting\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit ensures tight tolerance control for 2B class of fit\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement, non-interrupted thread design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting right-hand 1\/2-13 UNC threads to a 2B class of fit in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel.

Before use, confirm the pilot hole diameter is correct for a 1\/2-13 UNC thread and that the workpiece is securely fixtured. Apply appropriate cutting fluid for the workpiece material, particularly when tapping stainless or hardened steel. Do not reverse the tap under load without proper backlash compensation on manual setups.\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: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eOverall Length\u003c\/strong\u003e: 4.331 inches (110 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.921 inches (23.4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal (PMT15)\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\u003eInterrupted Thread\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\u003eSeries\u003c\/strong\u003e: 16515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.145 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: 1651503208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740933882162,"sku":"1651503208","price":87.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c73dd521834251f89ee379072088bca.jpg?v=1788828454","url":"https:\/\/voomisupply.com\/products\/osg-1651503208-spiral-point-tap-1-2-13-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
