Made from high-speed steel with a bright uncoated finish, this bottoming-style tap features a 2.5-thread chamfer that allows threading close to the bottom of a blind hole. The H5 thread limit ensures consistent Class 2B fit tolerances. At 1.8125 inches overall length with a 0.5 inch threading length, it is sized for small-fastener applications in precision assemblies. Machinists and toolroom technicians working with fine-pitch, small-diameter threads rely on this tap for clean, accurate internal thread forming.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading operations in materials that respond well to thread forming rather than thread cutting. Typical applications include tapping soft to medium-hardness metals in production machining, light manufacturing, and repair work where chip evacuation is a concern. The bottoming chamfer makes it the third tap in a tap set sequence or a standalone tool when threads must extend to the full depth of a shallow blind hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-48 UNC thread size for small-fastener blind hole applications\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 2.5 chamfered threads for threading near the base of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability in production use\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with standard tapping fluids\u003c\/li\u003e\n\u003cli\u003eH5 thread limit for Class 2B fit accuracy\u003c\/li\u003e\n\u003cli\u003eNo oil grooves, chipless thread forming design reduces clogging in blind holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming tap for 3-48 UNC blind hole threading applications in standard tap holders and tapping heads accepting a 0.1410-inch shank diameter with a 0.1100-inch square drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps should be installed by a qualified machinist in a tap holder or tapping head rated for the shank size. Always apply appropriate tapping fluid before use and confirm the workpiece is securely fixtured before operation. Ensure the drilled hole diameter matches the recommended tap drill size for 3-48 UNC thread forming to avoid tap breakage. Power off or deactivate any machine spindle before loading or changing taps.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2.5P\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.8125 inches\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: 0.1410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BXB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BALAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10525-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51974124667186,"sku":"10525-010","price":53.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bda7f6c319f70b2e647f3e39924d971.jpg?v=1789975961","url":"https:\/\/voomisupply.com\/products\/balax-10525-010-thread-forming-tap-3-48-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
