Made from Vanadium High Speed Steel (HSS-E) and finished with a Titanium Carbonitride (TiCN) coating, this tap delivers extended tool life and improved wear resistance compared to uncoated HSS tooling. The plug chamfer (3-5 thread lead) makes it suitable for through-hole tapping applications where the tap can pass completely through the workpiece. It is ground to an H3 thread limit and meets a 3B class of fit, producing threads within the tolerance range required for standard UNC fastener engagement. Machinists, toolroom operators, and production floor personnel are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe 2832408 is well suited for through-hole tapping operations in CNC machining centers, drill presses, and manual tapping setups. Its three-flute spiral point geometry pushes chips forward ahead of the cutting zone, reducing chip clogging in blind-hole or through-hole production runs. The TiCN coating reduces built-up edge on materials such as aluminum and stainless steel. Stated material applications include aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron, making this a versatile tap for general-purpose and production machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form, H3 thread limit, 3B class of fit for standard tolerance fastener threads\u003c\/li\u003e\n  \u003cli\u003eVanadium High Speed Steel (HSS-E) construction for toughness in interrupted cuts and harder materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces friction for longer tool life\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral point geometry pushes chips forward, suitable for through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 lead threads) allows the tap to start and cut progressively without aggressive lead-in\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature; not oversize; non-interrupted thread profile\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use spiral point tap for 1\/2-13 UNC through-hole tapping operations across standard machining applications.

Ensure the workpiece is securely fixtured and that the spindle or tapping head is properly aligned with the drilled pilot hole before engagement. Power down or disengage the tapping cycle before reversing to back out the tap. Use a suitable cutting fluid or tapping lubricant appropriate for the workpiece material to reduce heat and extend tap life, even though this tap does not have coolant-through capability.\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\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: 3B\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\u003eMaterial\u003c\/strong\u003e: Vanadium High Speed Steel (HSS-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.374 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.921 inches\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\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.117 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 280\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: 2832408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732614316338,"sku":"2832408","price":60.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6919163899b41a36795ea0f26f49cfec.jpg?v=1788745035","url":"https:\/\/voomisupply.com\/products\/osg-2832408-spiral-point-tap-1-2-13-unc-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
