Built from vanadium high-speed steel with a TiCN (Titanium Carbonitride) coating, it delivers improved wear resistance and longer tool life compared to uncoated HSS taps. The modified bottoming chamfer allows threading close to the bottom of blind holes while still providing adequate lead-in. With a 45-degree helix angle and 3 right-hand spiral flutes, chips are efficiently evacuated up and out of the hole. This tap is sized at 2-15\/16 inches overall length and is a standard choice for machinists, tool-and-die makers, and maintenance professionals working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe OSG 2941808 is suited for threading operations in alloy steel, carbon steel, cast iron, stainless steel, die steel, and hardened steel. The TiCN coating makes it particularly well-suited for abrasive and harder workpiece materials where uncoated taps wear prematurely. The modified bottoming chamfer makes it appropriate for blind-hole applications where full thread depth near the bottom of the hole is required. It is intended for use in CNC machining centers, manual mills, and tapping machines where a spiral flute geometry is preferred for chip control. Coolant-through capability is not included in this tap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread form with right-hand thread direction and H5 thread limit for controlled fit\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces friction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel construction provides toughness and heat resistance during high-speed tapping\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle on 3 spiral flutes promotes upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading to within a few threads of the hole bottom\u003c\/li\u003e\n  \u003cli\u003eOversize designation accommodates coating thickness to maintain accurate thread tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 3\/8-24 UNF internal threads in alloy steel, carbon steel, cast iron, stainless steel, die steel, and hardened steel workpieces.

Always ensure the workpiece is rigidly fixtured and the tap is properly aligned to the drilled hole before engaging. Apply a suitable cutting fluid or tapping compound rated for the workpiece material, as dry tapping is not recommended with HSS tooling. Follow shop safety procedures and machine manufacturer guidelines when setting spindle speed and feed rate for tapping operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches (74.6125 mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 67.4 mm\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, Stainless Steel, Die Steel, Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 290\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 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: 2941808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732884259122,"sku":"2941808","price":78.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02ab667616efb4d987ba47b34c328acb_7196e0e1-c5d1-47b2-b4a4-a56aff7f01ac.jpg?v=1788748032","url":"https:\/\/voomisupply.com\/products\/osg-2941808-spiral-flute-tap-3-8-24-unf-ticn-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
