Unlike cutting taps, thread forming taps cold-form material rather than removing chips, producing stronger threads with better surface finish. This tap is made from high-speed steel with a bright uncoated finish and carries a Class 3B fit with an H2 thread limit. The bottoming chamfer  -  2.5 chamfered threads  -  allows threading close to the bottom of a blind hole. Overall length is 1.8125 inches with a 0.5-inch thread length and a 0.141-inch shank diameter. Machinists and maintenance technicians in precision assembly environments install this tap in manual or CNC tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in ductile metals such as aluminum, mild steel, and copper alloys where chip-free thread forming is preferred. The 3-48 UNC size is common in small fastener applications found in electronics, instruments, and light mechanical assemblies. The bottoming chamfer makes it the right choice when thread engagement must begin as close to the hole bottom as possible. Right-hand thread direction is standard. The BXB series designation indicates BALAX bottoming geometry designed for consistent thread quality in production and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design cold-forms threads without chip production  -  ideal for blind holes\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer with 2.5 chamfered threads for threading close to hole bottom\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides wear resistance in production tapping\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit with H2 thread limit for tight tolerance thread profiles\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 3-48 UNC thread  -  common size for small fastener and instrument work\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement  -  compatible with standard tapping fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading applications requiring a 3-48 UNC right-hand thread profile with a Class 3B fit.

Apply appropriate tapping fluid or cutting oil before and during the tapping operation. Ensure the workpiece is securely fixtured and the tap is driven straight and square to the hole to avoid tap breakage at this small diameter. This operation is typically performed by a machinist or maintenance technician following applicable shop safety and tooling procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\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: BXB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 10522-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52088141087026,"sku":"10522-010","price":45.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec3c7f153f61df621c84c4f126dc10a2.jpg?v=1790060819","url":"https:\/\/voomisupply.com\/products\/balax-10522-010-thread-forming-tap-3-48-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
