Unlike cutting taps, thread forming taps displace material rather than remove it, resulting in stronger threads and no chip evacuation concerns. The 1400102405 is manufactured from cobalt high-speed steel for elevated heat and wear resistance, and carries a TiN (titanium nitride) coating to further extend tool life. The bottoming chamfer — 1 to 1.5 chamfered threads — allows threading close to the bottom of a blind hole. This tap is sized for precision fastener applications and is handled by machinists, tool-and-die makers, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThe 1400102405 is suited for blind hole threading operations in a range of workpiece materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Its material application codes (P and N) indicate compatibility with ferrous and non-ferrous metal groups. The bottoming geometry makes it the correct choice when thread depth must be maximized in a blind bore, such as in fixture plates, tooling blocks, and precision mechanical assemblies where 2-56 UNC fasteners are used.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip packing in blind holes\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer (1 to 1.5 threads) for threading close to the bottom of a blind bore\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction handles elevated cutting temperatures and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life across a broad material range\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, H4 thread limit for close tolerance thread production\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement — suitable for standard machine tool setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Secure the workpiece and use a rigid tapping setup or CNC rigid tap cycle to maintain alignment and prevent tap breakage in this small diameter. Apply appropriate tapping fluid for the workpiece material before tapping. Inspect the tap for wear regularly, as cobalt tooling in hardened materials will show accelerated flank wear over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 56\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 1.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.476 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\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\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 (14001)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 1400102405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728367550770,"sku":"1400102405","price":39.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_b87784fd-2116-4cff-a92c-54a5109cf3d6.jpg?v=1788690706","url":"https:\/\/voomisupply.com\/products\/osg-1400102405-thread-forming-tap-2-56-unc-bottoming-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
