Built from cobalt high-speed steel and finished with a TiN (titanium nitride) coating, this tap handles demanding materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. It produces M4x0.70 Metric Coarse threads to a 4H class of fit with a D4 thread limit. The modified bottoming chamfer, with 2 to 2.5 chamfered threads, allows threading close to the bottom of a blind hole. Installed by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis tap is intended for blind hole threading applications across a wide range of ferrous and non-ferrous workpiece materials. The thread forming method displaces material rather than cutting it, resulting in stronger threads and no chip evacuation concerns. It is well suited for production environments running alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum components where thread quality and tool life are critical. The right-hand thread direction and standard shank geometry fit conventional tapping chucks and CNC toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design produces chips-free M4x0.70 Metric Coarse internal threads in blind holes\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction provides heat resistance for harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life across ferrous and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2 to 2.5 chamfered threads) enables threading close to hole bottoms\u003c\/li\u003e\n\u003cli\u003e4H class of fit with D4 thread limit for precise, repeatable thread geometry\u003c\/li\u003e\n\u003cli\u003eCompatible with material application codes P and N covering steels and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Rigid tapping or a synchronized tapping head is strongly recommended to maintain accurate feed rate and avoid tap breakage. Apply appropriate tapping fluid or cutting oil for the workpiece material before tapping. Ensure the workpiece is securely fixtured and the spindle speed is set per the tap manufacturer guidelines for the material being tapped.\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\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 2.5P\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\/Finish\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: 0.168 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\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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\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: HY-PRO NRT (14101)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1410102605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728300671282,"sku":"1410102605","price":35.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_4c525902-d6cd-45bf-b67e-0d831a596a7e.jpg?v=1788690347","url":"https:\/\/voomisupply.com\/products\/osg-1410102605-thread-forming-tap-m4x0-70-metric-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
