Unlike cutting taps, this forming tap displaces material rather than cutting it, producing stronger threads with no chips to clear. It is manufactured from powdered metal high-speed steel with a bright, uncoated finish. The 4H class of fit and D4 thread limit provide consistent tolerance control for precision threaded assemblies. With a bottoming chamfer of 2.5 threads, it threads closer to the bottom of a blind hole than plug or taper style taps. Machinists, tool and die makers, and CNC operators use this tap in production environments where chip-free threading is required.\u003c\/p\u003e\u003cp\u003eThis tap is suited for blind hole threading in ductile metals such as aluminum, mild steel, and similar materials that respond well to cold forming. The bottoming chamfer makes it the correct choice when thread engagement is needed close to the base of a blind hole. It fits standard M4 tap holders and collets with a 0.168-inch shank diameter and a 0.131-inch square drive. The BXMSG series from BALAX is designed for consistent performance in both manual and CNC tapping setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting, eliminating chips in blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal high-speed steel construction provides wear resistance in repetitive production tapping\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer (2.5P) allows threading to within a very short distance of hole bottom\u003c\/li\u003e\n\u003cli\u003e4H class of fit with D4 thread limit ensures consistent, precise thread tolerance\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping attachments and CNC rigid tap cycles\u003c\/li\u003e\n\u003cli\u003eSingle oil groove supports lubrication delivery during the forming process\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard M4 tap holders, floating tap collets, and rigid tapping chucks accepting a 0.168-inch shank diameter.

Adequate lubrication or tapping fluid appropriate for the workpiece material must be applied to extend tap life and produce clean threads. Always secure the workpiece and ensure the tap is properly aligned to avoid tap breakage or thread distortion. Follow applicable shop safety procedures and machine manufacturer guidelines when using in CNC tapping cycles.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4x0.70\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: 4H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D4\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\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: Powdered Metal 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: 2.125 inches (53.98 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.470 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.750 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches (4.27 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches (3.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\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: BXMSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 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: 18074-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":51972050878770,"sku":"18074-010","price":49.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e3287bae53c9d255fa76aace16af7db.jpg?v=1789962023","url":"https:\/\/voomisupply.com\/products\/balax-18074-010-thread-forming-tap-m4x0-70-4h-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
