Unlike cutting taps, thread forming taps cold-form the thread profile by displacing material rather than cutting chips, producing stronger threads with better surface finish. This tap is manufactured from high-speed steel (HSS) and coated with titanium nitride (TiN) for improved wear resistance and lubricity. It carries a 4H class of fit with a D6 thread limit and features a bottoming chamfer with 2.5 chamfered threads, allowing threads to be formed close to the bottom of a blind hole. Machinists and toolroom professionals install this tap in CNC machining centers, drill presses, and tapping machines.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading in ductile and malleable materials including aluminum, copper, brass, and mild steel where chip evacuation is a concern. The bottoming chamfer makes it appropriate for applications requiring maximum thread depth in a blind hole. With an overall length of 3.375 inches and a 1-inch thread length, it fits standard tap holders sized for this shank diameter. The single oil groove aids lubricant distribution during the forming process. Right-hand thread direction is standard for conventional tapping operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design cold-forms threads without chips, reducing risk of chip packing in blind holes\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating improves surface hardness and extends tool life\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 2.5 chamfered threads for threading close to the bottom of a blind hole\u003c\/li\u003e\n\u003cli\u003e4H class of fit with D6 thread limit for consistent, accurate thread tolerance\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a wide range of ductile workpiece materials\u003c\/li\u003e\n\u003cli\u003eSingle oil groove supports lubricant flow during forming\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard tap holders and tapping heads that accept a 0.367-inch shank diameter with a 0.275-inch square drive.

Ensure the workpiece is securely fixtured and the tap is properly aligned to avoid thread distortion or tap breakage. Apply a suitable tapping fluid or cutting oil throughout the operation. Power down or de-energize the machine before changing or inspecting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 4H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D6\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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches (85.72 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches (9.32 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches (6.99 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\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: BXMB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: 18946-00T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52054932062514,"sku":"18946-00T","price":90.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c5b2534e311929f50f867ed27817a09.jpg?v=1790037212","url":"https:\/\/voomisupply.com\/products\/balax-18946-00t-m12x1-75-thread-forming-tap-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
