Manufactured from vanadium high speed steel with a steam oxide coating, this tap offers improved lubricity and corrosion resistance during cutting. It features a plug chamfer for use in through-hole applications, a 3-flute design that pushes chips ahead of the cutting action, and conforms to a 2B class of fit with an H2 thread limit. Installed by machinists and maintenance trades in production and repair environments, it is suited for hand tapping, drill press, and CNC tapping operations.\u003c\/p\u003e\n\u003cp\u003eThe OSG 2532401 is appropriate for through-hole tapping applications in aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and hardened steel. The plug chamfer makes it the standard choice when the tap can pass completely through the workpiece. It is commonly used in general machining, fabrication shops, and field maintenance where 1\/2-13 UNC threaded fastener holes are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, keeping flutes clear in through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eVanadium high speed steel construction provides wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves lubricity and reduces galling during cutting\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer — optimized for through-hole applications\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit and 2B class of fit for standard UNC tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 3-flute configuration; no coolant-through required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 1\/2-13 UNC through-holes in aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 1\/2-13 UNC before tapping. Apply an appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and improve thread quality. Do not force the tap if resistance increases sharply — back off to break chips before continuing.\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (HSS-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\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: 1-21\/32 inches (0.921 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\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\u003eSeries\u003c\/strong\u003e: 250\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: 2532401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750238847282,"sku":"2532401","price":60.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/975f303840a8e29ca2f87b2a389a7441.jpg?v=1788914465","url":"https:\/\/voomisupply.com\/products\/osg-2532401-spiral-point-tap-1-2-13-unc-3-flute-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
