Manufactured from high-speed steel with a titanium nitride (TiN) coating, it offers improved wear resistance and reduced friction compared to uncoated taps. The plug chamfer profile distributes cutting load across several leading threads, making it well suited for through-hole tapping applications. With 2 flutes and an H2 thread limit, this tap produces a 2B class of fit, which is the standard tolerance for general-purpose fastener assembly. Machinists and maintenance technicians working with fine-pitch miniature threads will find this tap appropriate for precision work in metals.\u003c\/p\u003e\u003cp\u003eThis tap is used in through-hole tapping operations where a 1-72 UNF thread is required. It is common in instrument manufacturing, electronics assembly, precision mechanical assemblies, and any application requiring small-diameter fine-pitch threaded holes. The right-hand thread direction and plug chamfer make it compatible with standard tapping operations on drill presses, CNC machining centers, and hand-tapping setups. The TiN coating extends tool life in higher-volume production runs as well as in intermittent maintenance use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-72 UNF thread form with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with TiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003ePlug chamfer distributes cutting load for through-hole tapping\u003c\/li\u003e\n\u003cli\u003eH2 thread limit produces 2B class of fit for standard general-purpose assemblies\u003c\/li\u003e\n\u003cli\u003e2-flute design aids chip evacuation in through-hole applications\u003c\/li\u003e\n\u003cli\u003e0.1410-inch shank diameter and 3\/8-inch thread length suit miniature thread work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for applications requiring a 1-72 UNF plug spiral point tap with a 2B class of fit and H2 thread limit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and operated by machinists or maintenance technicians using a tap wrench, tapping head, or CNC rigid tapping cycle. Ensure the workpiece is properly secured and the pilot hole is drilled to the correct tap drill diameter for 1-72 UNF threads before tapping. Apply appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Do not force the tap through the hole; back off periodically to break chips and prevent tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-72\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008027AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751258325298,"sku":"K008027AS25","price":36.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c41019149bacb9a2e9a5d3b2287d3da.jpg?v=1788922520","url":"https:\/\/voomisupply.com\/products\/hertel-k008027as25-spiral-point-tap-1-72-unf-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
