Built from high speed steel with a TiN (titanium nitride) coating, this tap offers improved surface hardness and wear resistance compared to uncoated HSS tooling. It features a plug chamfer for general-purpose hand tapping, a 3B class of fit for standard tolerance threaded assemblies, and an H1 thread limit for close control of thread size. Overall length is 1-11\/16 inches with a thread length of 3\/8 inches. Machinists, tool and die makers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for hand tapping 1-72 UNF threads in through-holes and blind holes in ferrous and non-ferrous metals, plastics, and similar materials where fine-pitch, small-diameter internal threads are required. The plug chamfer style — typically 3 to 5 threads of taper — makes it appropriate for starting threads in through-holes or continuing threads after a taper tap in blind-hole applications. It is commonly used in instrument manufacturing, electronics assembly, and precision mechanical work where 1-72 thread series components are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-72 UNF thread form with right-hand direction for standard fine-pitch small fastener applications\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life in production and repetitive hand tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style suits through-hole and general-purpose blind-hole tapping\u003c\/li\u003e\n  \u003cli\u003e3B class of fit and H1 thread limit deliver consistent, close-tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003e2-flute straight flute geometry for chip clearance in short-chipping materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap handles and tapping fixtures that accept the shank size appropriate for 1-72 UNF hand taps.

Ensure the workpiece is securely fixtured and the tap is started perpendicular to the hole to avoid thread misalignment or tap breakage at this small diameter. Apply a suitable cutting fluid or tapping compound for the workpiece material before beginning the threading operation. Back the tap off periodically to break chips and clear flutes, particularly in blind-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eChamfer Type\u003c\/strong\u003e: Plug\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: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 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: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3\/8 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: 0.06 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008022AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746513453362,"sku":"K008022AS25","price":42.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e6e1b7c2ef50f6ccde18b9144f14ba9.jpg?v=1788870947","url":"https:\/\/voomisupply.com\/products\/hertel-k008022as25-hand-tap-1-72-unf-tin-hss-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
