It is manufactured from powdered metal high-speed steel and finished with a Bal-Plus coating for extended tool life in demanding production environments. With a 6H class of fit and D10 thread limit, this tap produces accurate, consistent threads suited to tight-tolerance assemblies. The overall length is 2.719 inches with a thread length of 0.880 inches and a tapping depth of 1.125 inches. Licensed machinists, toolroom operators, and production technicians working in die casting shops are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis tap is specifically engineered for blind hole threading in die cast aluminum components, reflecting its BXDIECAST series designation. The thread forming process displaces material rather than cutting it, which eliminates chips in the hole and produces a stronger, work-hardened thread form. It is well suited to high-volume production cells where chip management in blind bores presents a reliability problem. The 2.5-thread chamfer length (bottoming style) allows threading close to the bottom of a blind hole, making it a practical choice for parts with limited thread engagement depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer with 2.5 thread lead for threading near the base of blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal high-speed steel construction for improved wear resistance over conventional HSS\u003c\/li\u003e\n\u003cli\u003eBal-Plus coating reduces friction and extends tap life in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eThread forming design eliminates chips, reducing tap breakage risk in blind bore applications\u003c\/li\u003e\n\u003cli\u003e6H class of fit with D10 thread limit for precise metric thread tolerance control\u003c\/li\u003e\n\u003cli\u003eSingle oil groove supports lubrication flow during the forming process\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming in die cast aluminum workpieces as part of the BXDIECAST series.

Ensure the spindle is fully stopped and the workpiece is securely fixtured before tool changes. Use a cutting or forming fluid appropriate for aluminum to prevent galling and extend tool life. Follow applicable shop safety procedures and manufacturer feed rate recommendations for thread forming taps in non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1.25\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: D10\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\u003eOverall Length\u003c\/strong\u003e: 2.719 inches (69.06 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.880 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.125 inches (28.57 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches (8.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches (6.05 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\/Finish\u003c\/strong\u003e: Bal-Plus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Die Cast Aluminum\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: BXDIECAST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 18680-91L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52054035726642,"sku":"18680-91L","price":64.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3808d8809a29c91096d7be535caca657.jpg?v=1790036558","url":"https:\/\/voomisupply.com\/products\/balax-18680-91l-thread-forming-tap-m8x1-25-bottoming-6h","provider":"Voomi Supply","version":"1.0","type":"link"}
