Built from HSS-E cobalt high-speed steel, it delivers added heat and wear resistance compared to standard HSS tooling. The plug chamfer distributes cutting load across the leading threads for reliable thread initiation. With a 4-48 UNF thread form, 3 flutes, and a 2B class of fit, this tap produces clean, dimensionally consistent internal threads in small-diameter applications. Machinists and maintenance technicians reach for this tap when precision threaded holes are required in ferrous metals at fine pitch.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations on small fastener threads in the 4-48 UNF specification. It performs in production and maintenance environments where consistent thread quality in steel is critical. The spiral point geometry pushes chips forward ahead of the tap, making it especially well suited for through-hole work in CNC machining centers, drill presses, and hand-tapping fixtures. The right-hand thread direction and H2\/H3 thread limit make it compatible with standard 2B tolerance requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS-E cobalt construction provides enhanced hardness and heat resistance for tapping steel\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing chip packing in through-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load gradually for smooth thread entry\u003c\/li\u003e\n  \u003cli\u003e3 flutes with H2\/H3 thread limit ensure 2B class of fit compliance\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish allows visual wear inspection during service life\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard drive compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of 4-48 UNF internal threads in steel applications, conforming to 2B class of fit tolerances per Series 3902.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and operated by machinists or maintenance technicians using a standard tap wrench, tapping head, or CNC rigid tapping cycle. Before tapping, ensure the workpiece is secured and the pilot hole diameter matches the recommended tap drill size for 4-48 UNF. Use an appropriate cutting fluid for steel to extend tool life and improve thread finish. Never reverse a spiral point tap under load without confirming chip clearance ahead of the flutes.\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 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0208 inches\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\/H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS-E Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.882 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4330 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.2760 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3902\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9039020028450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753172107570,"sku":"9039020028450","price":44.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9dcc45d8d24f27d785a46f16c9fbfd1_6b34b366-8981-4d90-b202-5ee72cd96bf7.jpg?v=1788933491","url":"https:\/\/voomisupply.com\/products\/guhring-9039020028450-spiral-point-tap-4-48-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
