Built from powdered metal high-speed steel (PM-HSS) and finished with a TiCN coating, this tap is engineered for cold-forming internal threads in steel without cutting or generating chips. Thread forming taps displace material rather than remove it, producing stronger threads with better surface finish. The TiCN coating reduces friction and extends tool life in demanding steel applications. With a D9 thread limit, a 0.79-inch thread length, and an overall length of 2.5 inches, this tap is suited for precision blind hole work in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 18479-91C is intended for blind hole threading in steel workpieces where chip evacuation is a concern and thread strength is a priority. The bottoming chamfer  -  approximately 2.5 threads  -  allows the tap to form threads close to the bottom of a blind hole. This tap is installed by machinists, toolroom technicians, and maintenance professionals using standard tapping equipment or CNC machining centers. The BXSTEEL series is specifically developed for steel material applications, making this tap appropriate for both manual and machine tapping operations where consistent 6H thread accuracy is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design eliminates chip buildup in blind holes and produces stronger threads than cut taps\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and heat buildup, extending tool life in steel applications\u003c\/li\u003e\n  \u003cli\u003ePowdered metal high-speed steel construction provides superior wear resistance over conventional HSS\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (2.5P) allows threading close to the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003eD9 thread limit maintains consistent 6H class of fit across production runs\u003c\/li\u003e\n  \u003cli\u003eSingle oil groove supports lubrication during the forming process\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in steel per the BXSTEEL series application.

Apply a suitable tapping fluid or cutting oil rated for steel to the tap and workpiece before operation. Ensure the spindle speed and feed rate are matched to the tap manufacturer recommendations for thread forming in steel. Do not use this tap in cast iron, brittle materials, or any material that does not have sufficient ductility for cold forming.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M6x1.00\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\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: D9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.79 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.00 inches (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches (6.48 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.191 inches (4.85 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal High-Speed Steel\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\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: BXSTEEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 18479-91C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51972243259698,"sku":"18479-91C","price":62.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25fe3eecb25a2c21cd0fb647e00d18d4.jpg?v=1789964853","url":"https:\/\/voomisupply.com\/products\/balax-18479-91c-m6x1-00-thread-forming-tap-6h-bottoming-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
