Unlike cut taps, thread forming taps cold-form material rather than cutting chips, producing stronger threads with no swarf to clear from the hole. Made from high-speed steel with a bright uncoated finish, this tap carries a 6H class of fit and a D6 thread limit, making it suited for close-tolerance threaded holes in production and maintenance applications. It is part of the BALAX BXMB series and is intended for use by machinists, tool and die makers, and precision manufacturing technicians.\u003c\/p\u003e\n\u003cp\u003eThis tap is applied in blind hole threading operations where a full thread form is needed close to the bottom of the hole. The bottoming chamfer of 2.5 thread pitches allows the tap to form threads nearer to the bottom of a blind bore compared to plug or taper chamfer styles. Typical use cases include threading small metric holes in aluminum, brass, copper, and other ductile metals in precision manufacturing, electronics assembly, and mechanical component fabrication. No coolant-through capability is present, so external cutting fluid or tapping fluid applied at the workpiece is standard practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer with 2.5P allows thread forming close to the bottom of blind bores\u003c\/li\u003e\n  \u003cli\u003eM2.5x0.45 metric coarse thread size with 6H class of fit and D6 thread limit for close-tolerance work\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides wear resistance suitable for general production use\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish  -  compatible with a wide range of tapping fluids and lubricants\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, no oil grooves, BXMB series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming tap for M2.5x0.45 metric coarse blind hole applications requiring a 6H class of fit in ductile workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using a tap wrench, tapping head, or CNC rigid tapping cycle with appropriate spindle speed for the workpiece material. Secure the workpiece fully before tapping and ensure the pilot hole diameter is correct for thread forming, as forming taps require a larger pilot hole than cut taps for the same thread size. Apply tapping fluid to the tap and hole before and during operation. Never force a tap that has stalled  -  back out carefully to avoid breakage in small-diameter taps.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2.5x0.45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D6\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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 (46.04 mm)\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: 0.141 inches (3.58 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches (2.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BXMB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: BALAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17426-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51971267461426,"sku":"17426-010","price":47.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6c63c4284090ad229a56b06d0c2401e.jpg?v=1789955229","url":"https:\/\/voomisupply.com\/products\/balax-17426-010-thread-forming-tap-m2-5x0-45-6h-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
