Built from powdered metal and coated with TiCN, it delivers extended tool life in abrasive and hard-material applications where high-speed steel taps wear prematurely. The modified bottoming chamfer allows threading close to the bottom of blind holes, making it well suited for tight-tolerance production work. With 5 flutes, a 2B class of fit, and an H5 thread limit, this tap produces consistent, dimensionally accurate threads that meet standard fastener assembly requirements.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for machine use in CNC machining centers, drill presses, and tapping machines. It is a strong fit for shops working with hardened steel components, alloy steel parts, and similar ferrous materials in both production and job-shop environments. The right-hand thread configuration and straight flute geometry make it appropriate for through-hole and shallow blind-hole applications where chip evacuation is managed by the setup. Machinists and tooling specialists working with close-tolerance assemblies will find the 2B class and H5 limit appropriate for general-purpose threaded fastener interfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form with 2B class of fit and H5 thread limit for consistent, in-spec threads\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer for threading near the base of blind holes\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides greater wear resistance than standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in hardened and alloy steel\u003c\/li\u003e\n  \u003cli\u003e5-flute design increases thread contact and improves finish quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 3\/8-16 UNC holes in hardened steel and alloy steel workpieces.

Ensure the spindle is fully stopped and the machine is in a safe state before changing or inspecting the tap. Use appropriate cutting fluid or tapping compound rated for hardened and alloy steel to protect the coating and maintain tool life. Verify hole diameter and depth before tapping to avoid tap breakage in blind holes.\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\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: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/4 inches (0.751 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches (2.938 inches decimal)\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: 1.251 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hardened Steel, Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 10051\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.079 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: 1005112208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737456279858,"sku":"1005112208","price":89.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/327e710aa308cc6eade8f5e087b6ea6b.jpg?v=1788788785","url":"https:\/\/voomisupply.com\/products\/osg-1005112208-straight-flute-tap-3-8-16-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
