It cuts a 3-48 UNC right-hand thread and is suited to threading holes close to the bottom, where a bottoming chamfer is required to maximize thread engagement depth. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance in short-run and production tapping applications. With a 0.5-inch thread length and an overall length of 1.8125 inches, it fits standard tap holders and T-handle wrenches used in manual and machine tapping setups. The H2 thread limit ensures dimensional control within industry-standard tolerance ranges for a 2B class of fit.\u003c\/p\u003e\u003cp\u003eThis tap is sized for the smallest common machine screw thread in the UNC series, making it a standard choice when threading 3-48 tapped holes in instrument housings, electronic enclosures, small mechanical assemblies, and precision hardware. The 3-flute straight flute geometry is well matched to through-hole and shallow blind-hole applications. It is installed by machinists, tool-and-die workers, maintenance technicians, and assembly personnel working on equipment requiring small-diameter machine screw threads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer allows threading to the full depth of blind holes\u003c\/li\u003e\n\u003cli\u003e3-48 UNC thread form with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eH2 thread limit holds 2B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003e3 straight flutes for chip management in short-chipping materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3-48 UNC bottoming tap compatible with T-handle tap wrenches, tapping attachments, and CNC tapping heads sized for small-diameter taps.

Always use a properly sized tap drill for a 3-48 UNC thread before tapping, and apply appropriate cutting fluid to reduce friction and extend tool life. Secure the workpiece firmly to prevent movement during the tapping operation. Reverse the tap periodically during hand tapping to break chips and prevent tap breakage in blind holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\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: Bottoming\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.8125 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: 0.15 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: K008060AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739990262066,"sku":"K008060AS","price":28.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84806235ac3ffc591fba5690948f8dff.jpg?v=1788821180","url":"https:\/\/voomisupply.com\/products\/hertel-k008060as-straight-flute-tap-3-48-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
