Built from powdered metal with a TiCN (Titanium Carbonitride) coating, this tap delivers superior wear resistance and heat dissipation compared to standard high-speed steel alternatives. The spiral point geometry pushes chips forward ahead of the cutting zone, making it well suited for through-hole tapping operations where chip evacuation is critical. It carries an H3 thread limit and a 3B class of fit for general-purpose precision threading.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in machining environments where difficult workpiece materials demand a more durable tooling solution. The TiCN coating provides a hard, low-friction surface that extends tool life when threading stainless steel, titanium, and nickel-based alloys  -  materials that are prone to work hardening and galling. It is appropriate for use on CNC machining centers, manual mills, and drill presses equipped with a tapping head. Machinists and tool-and-die professionals working in job shops, aerospace component manufacturing, and industrial production environments will find this tap applicable to a wide range of through-hole tapping applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces friction for extended tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003ePowdered metal substrate provides superior toughness and wear resistance over conventional HSS\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, optimizing chip flow in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with 3B class of fit for consistent, precise thread tolerance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 3 flutes, plug chamfer for easy thread entry and alignment\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; suitable for use with external cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole tapping of 3\/8-16 UNC threads in hardened steel, stainless steel, high-nickel alloy, titanium, and alloy steel workpieces.

Always power down and lock out the machine before changing tooling. Use a suitable cutting fluid or tapping compound rated for the workpiece material  -  dry tapping is not recommended for stainless steel or titanium. Verify that the tap is properly aligned with the pilot hole before engaging the cut to prevent tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 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: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hardened Steel, Stainless Steel, High-Nickel Alloy, Titanium, Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.751 inches (1-1\/4 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 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: 312TI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.081 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: 1105612108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743953912114,"sku":"1105612108","price":85.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77844b87c50fd9a79220f3bca23577c0.jpg?v=1788851873","url":"https:\/\/voomisupply.com\/products\/osg-1105612108-spiral-point-tap-3-8-16-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
