Built from cobalt high-speed steel and finished with a TiN coating, this tap produces M4x0.70 metric coarse threads to a 4H class of fit with a D4 thread limit. The bottoming chamfer (1 to 1.5 thread pitch) allows threading close to the bottom of a blind hole. Right-hand thread direction. Overall length is 2.126 inches with a thread length of 0.3307 inches and a tapping depth of 0.7717 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production and maintenance threading operations in alloy steel, carbon steel, aluminum, die steel, hardened steel, and stainless steel workpieces. The thread forming method displaces material rather than cutting it, resulting in stronger threads and no chip evacuation concerns in blind hole applications. Machinists, tool and die makers, and maintenance technicians working with M4 fastener threads in tight-tolerance assemblies will find this tap appropriate for both CNC and manual tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design eliminates chip packing in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides heat and wear resistance in tough alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in high-volume applications\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (1 to 1.5P) threads to near-bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e4H class of fit and D4 thread limit for standard metric tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through required; suitable for conventional flood or manual tapping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for M4x0.70 metric coarse blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Secure the workpiece and ensure the tap is aligned perpendicular to the hole before engaging to avoid cross-threading or tap breakage. Use a calibrated tapping chuck or torque-controlled driver when possible to avoid overloading the tap shank. Follow applicable shop safety practices and machine guarding requirements when power tapping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.126 inches (54.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3307 inches (8.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.7717 inches (19.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1680 inches (4.27 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1310 inches (3.33 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 6.35 mm\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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14101)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1410102405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51750843285810,"sku":"1410102405","price":38.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04585df72c51519148fe7ee505b04d0a.jpg?v=1788920124","url":"https:\/\/voomisupply.com\/products\/osg-1410102405-thread-forming-tap-m4x0-70-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
