Built from cobalt high-speed steel with a titanium nitride (TiN) coating, it handles demanding materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The plug chamfer with 4 to 4.5 chamfered threads suits through-hole threading applications where the tap enters from a clearance hole. The H10 thread limit controls the tolerance class of the finished thread. At 2.125 inches overall length and a 0.168-inch shank diameter, this tap is sized for standard machine tool chucks and tapping heads used in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations producing 8-32 UNC right-hand threads. It is well suited for machine shops, maintenance facilities, and manufacturing lines working with the listed ferrous and non-ferrous materials. The chipless forming action reduces the risk of chip packing in blind approaches and extends tool life compared to cut taps in suitable ductile materials. Machinists and tool-and-die technicians are the primary users in both CNC and manual tapping setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt HSS construction provides heat resistance for harder ferrous materials including hardened steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in high-cycle production runs\u003c\/li\u003e\n  \u003cli\u003eThread forming design produces no chips, eliminating chip-related tool breakage and tap extraction issues\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 4 to 4.5 chamfered threads optimized for through-hole threading entry\u003c\/li\u003e\n  \u003cli\u003eH10 thread limit ensures controlled internal thread tolerance for 8-32 UNC specifications\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping equipment and CNC programs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Secure the workpiece and use a tapping fluid or cutting oil appropriate for the material being tapped. Power down or disengage the spindle before loading or removing the tap from the chuck. Follow shop safety practices and applicable OSHA machine guarding requirements when operating tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4 to 4.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT (14001)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Applications\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\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: 1400115905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741555654962,"sku":"1400115905","price":38.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9e0a7535aeb52c331c9ab34d6077839_baac3c73-5988-4ab0-bf1f-bec13c706708.jpg?v=1788832158","url":"https:\/\/voomisupply.com\/products\/osg-1400115905-thread-forming-tap-8-32-unc-plug-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
