It cuts a 3-48 UNC right-hand thread with 3 flutes and a plug chamfer that eases entry and distributes cutting load across multiple teeth. The tap is manufactured from HSS-E cobalt high-speed steel and carries a TiN (titanium nitride) coating that reduces friction and extends tool life in production threading operations. At 1.811 inches overall length with a 0.5 inch thread length and a shank diameter of 0.141 inches, this tap is sized for small-fastener work where precision and consistency are critical. Thread limit is H2\/H3, class of fit is 2B.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading through-holes in steel components where chip evacuation is a priority. The spiral point design pushes chips forward ahead of the tap rather than packing them in the flutes, making it well-suited for production environments and CNC tapping cycles. It is commonly used by machinists, tool-and-die technicians, and maintenance professionals working with small 3-48 fastener applications in light to medium steel. Coolant-through is not supported on this tap, so flood or mist coolant at the outside is the standard approach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-48 UNC thread form, right-hand cut, class of fit 2B\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n\u003cli\u003eHSS-E cobalt substrate improves heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and increases tool life in steel applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides stable entry and distributes cutting forces\u003c\/li\u003e\n\u003cli\u003eThread limit H2\/H3 for consistent tolerance control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading applications requiring a 3-48 UNC right-hand thread in steel.

Always secure the workpiece and ensure the tap is aligned perpendicular to the hole before beginning the threading cycle. Use appropriate cutting fluid or flood coolant directed at the tool exterior, as this tap does not support coolant-through delivery. Follow shop safety procedures and applicable OSHA standards when operating tapping equipment.\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\u003eThreads per Inch\u003c\/strong\u003e: 48\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: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\/H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\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\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.811 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0208 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: 3916\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9039160025150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748698521906,"sku":"9039160025150","price":44.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8767999dd1549bc6450fdc8be91dbc0_15c703ab-6536-4d70-8394-59015deb72a4.jpg?v=1788896931","url":"https:\/\/voomisupply.com\/products\/guhring-9039160025150-spiral-point-tap-3-48-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
