Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers improved wear resistance and surface hardness compared to uncoated HSS tooling. The plug chamfer geometry, with approximately 3-5 threads of taper, makes it a general-purpose choice suited for through holes and blind holes with adequate clearance. Three flutes provide chip clearance and cutting stability at this small thread diameter. Thread limit is H2, and the class of fit is 2B\/3B, covering both standard commercial and precision thread applications. This tap is installed by machinists and maintenance trades working with metal components.\u003c\/p\u003e\n\u003cp\u003eThe K008116AS25 is used in machine shop, maintenance, repair, and production environments where 5-40 UNC threads are required. Its compact overall length of 1-15\/16 inches and thread length of 5\/8 inches make it appropriate for small fastener tapping operations in aluminum, mild steel, brass, and similar machinable materials. The TiN coating extends tool life in higher-volume tapping applications. It is compatible with standard tap wrenches, tapping heads, and CNC or manual drill press setups at appropriate speeds for the material and thread size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread form with H2 thread limit for precise fit control in 2B and 3B class applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness for hand and machine tapping\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating increases surface hardness and reduces tool wear\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) suits both through-hole and blind-hole applications with clearance\u003c\/li\u003e\n  \u003cli\u003eThree-flute design aids chip evacuation at small thread diameters\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, no coolant-through — standard tooling setup required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style replacement or direct-use tap for any application requiring a 5-40 UNC straight flute plug tap with H2 thread limit and 2B\/3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a tap wrench, tapping head, or CNC spindle with the correct tap adapter for the shank size. Power down or disengage machine drives before manually seating the tap. Use appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Do not force the tap if resistance increases unexpectedly — back off to break and clear chips before continuing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B \/ 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008116AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733616820530,"sku":"K008116AS25","price":26.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/597cdb1153d0d64a3218b90fd85aedf8.jpg?v=1788756964","url":"https:\/\/voomisupply.com\/products\/hertel-k008116as25-straight-flute-tap-5-40-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
