Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during tapping operations. The 10-24 UNC thread form is cut with 4 flutes, and the bottoming chamfer allows threading close to the bottom of blind holes. Overall length is 2-3\/8 inches with a thread length of 7\/8 inches. The H3 thread limit holds Class 2B and 3B fits for standard tolerance requirements. Machinists and maintenance technicians in production, toolroom, and field settings rely on this tap for accurate, repeatable threads.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for tapping 10-24 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The bottoming chamfer makes it particularly useful where the full thread depth must extend to the bottom of a blind hole, often as a second-pass tap following a plug or taper tap. The TiN coating supports higher cutting speeds and improves chip flow across all listed material applications. It is appropriate for hand tapping, drill press, or CNC tapping operations where straight-flute geometry is preferred for its rigidity in short-chipping materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eTiN coating extends tool life and reduces cutting friction\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles steel, cast iron, and aluminum\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit suits Class 2B and 3B fit requirements\u003c\/li\u003e\n  \u003cli\u003e4-flute straight design provides rigidity for short-chipping materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 10-24 UNC internal threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces where a bottoming chamfer and Class 2B or 3B fit are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTapping operations should be performed by a qualified machinist or maintenance technician familiar with thread cutting procedures. Secure the workpiece firmly and use a properly sized tap wrench, tapping head, or CNC rigid tap cycle before starting. Apply an appropriate cutting fluid for the workpiece material to promote chip evacuation and reduce tool wear. Inspect the tap for wear or chipping before each use, and back off periodically during hand tapping to break chips and 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: 10-24 UNC\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B and 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 7\/8 inches (0.6181 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches (2.374 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.152 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.4724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eSeries\u003c\/strong\u003e: 102\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 1025005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755506172210,"sku":"1025005","price":25.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccb238e484622141d2bd34298fef77b7_4c8514d6-b1cf-44e2-bf5f-6d2ac9394e76.jpg?v=1788955611","url":"https:\/\/voomisupply.com\/products\/osg-1025005-straight-flute-tap-10-24-unc-bottoming-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
