Built from high-speed steel with a bright, uncoated finish, this tap delivers consistent thread geometry across a wide range of ferrous and non-ferrous materials. It features a taper chamfer for easy thread entry and a 2B class of fit, which meets standard tolerance requirements for most threaded fastener assemblies. The right-hand thread direction and H2 thread limit keep dimensional control tight. Overall length is 1.875 inches, and the tool weighs approximately 0.1 pounds. Machinists, tool-and-die workers, and maintenance technicians use this tap for hand or machine tapping where fine unified threads are required.\u003c\/p\u003e\n\u003cp\u003eThe K008100AS is suited for light to medium threading work on small-diameter holes calling for a 4-48 UNF thread form. The taper chamfer style distributes cutting load across several leading threads, making it well-suited for through-hole applications and for starting threads in blind holes where a bottoming tap is not yet needed. Typical applications include instrument components, precision assemblies, and small fastener repair work where the 4-48 fine thread provides greater holding strength than a coarse-thread equivalent of the same nominal diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-48 UNF thread size with taper chamfer for smooth thread entry and distributed cutting load\u003c\/li\u003e\n  \u003cli\u003e2B class of fit meets standard tolerance requirements for general-purpose threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for controlled dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e3 straight flutes for chip clearance in through-hole and short blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating thickness variation affecting thread tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or general-use straight flute tap for 4-48 UNF threading operations in hand-tapping fixtures, drill presses, tapping heads, and CNC machines equipped with a tap holder of the appropriate shank size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by a machinist or tool-and-die technician using a tap wrench, tapping head, or rigid machine holder sized to the shank. Ensure the workpiece is securely fixtured and the pilot hole diameter is correctly sized for a 4-48 UNF thread before beginning. Apply appropriate cutting fluid to reduce heat and extend tool life, particularly in ferrous materials. Inspect flutes for chips or damage before each use and replace the tap if cutting edges show signs of wear to avoid thread form degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48\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: Taper\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.875 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: Bright \/ Uncoated\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: 0.1 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: K008100AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728064151858,"sku":"K008100AS","price":21.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85ac8790a46c63fd67c6cbc7e72bc356.jpg?v=1788687304","url":"https:\/\/voomisupply.com\/products\/hertel-k008100as-straight-flute-tap-4-48-unf-taper-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
