Manufactured from cobalt high-speed steel and finished with a TiN (titanium nitride) coating, this tap displaces material rather than cutting chips, producing strong, work-hardened threads with no chip evacuation concerns. The modified bottoming chamfer with 2 to 2.5 chamfered threads allows threading close to the bottom of blind holes. It carries a 4H class of fit with a D3 thread limit, making it suitable for precision threaded connections in tight-tolerance components. This tap is part of the OSG HY-PRO NRT series and is installed by machinists, toolroom technicians, and production operators.\u003c\/p\u003e\n\u003cp\u003eThe 1410100205 is suited for blind hole threading in a wide range of ferrous and non-ferrous materials. Rated for use in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum, it covers a broad material application range. Its small M1.7 thread size makes it a common choice for precision instrument components, medical device hardware, electronics enclosures, and miniature fastener applications where clean thread form and dimensional accuracy are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material for chip-free blind hole threading\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides heat and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in production environments\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5P) enables threading close to hole bottom\u003c\/li\u003e\n  \u003cli\u003e4H class of fit with D3 thread limit for consistent, precision thread geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping chucks and tap holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in blind hole threading operations on alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces.

Secure the workpiece and use a calibrated torque-controlled tapping machine or CNC tapping cycle to avoid tap breakage at this small diameter. Apply appropriate tapping fluid for the workpiece material before use. Inspect the tap for wear or distortion regularly, as small-diameter forming taps are sensitive to misalignment and overloading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M1.7x0.35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\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: D3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.689 inches (42.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches (9.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.4134 inches (10.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches (3.58 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches (2.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 4.76 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: HY-PRO NRT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\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: 1410100205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736859836722,"sku":"1410100205","price":48.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_02551c8f-edc6-4507-8589-4b2b027f8c35.jpg?v=1788781191","url":"https:\/\/voomisupply.com\/products\/osg-1410100205-thread-forming-tap-m1-7x0-35-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
