Built from powdered metal and coated with titanium nitride (TiN), it delivers elevated hardness and wear resistance suited to stainless steel and other demanding materials. With three flutes and a plug chamfer, the tap progressively engages the workpiece and pushes chips ahead of the cutting edge into the through-hole. The right-hand thread direction and H2 thread limit support accurate Class 3B fits. Overall length is 1.882 inches with a shank diameter of 0.141 inches. This tap is appropriate for machinists and maintenance trades requiring reliable fine-thread formation at small diameters.\u003c\/p\u003e\u003cp\u003eThis tap is intended for through-hole threading operations where chip evacuation ahead of the tap is acceptable. The 4-48 UNF thread designation makes it suited for small fastener applications in precision assemblies, instrument enclosures, and mechanical components where fine thread engagement is required. The TiN coating reduces friction and extends tool life, particularly when threading stainless steel or similarly abrasive alloys. It is used in CNC tapping, drill press, and hand-tapping setups where a 4-48 right-hand thread is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-48 UNF thread form with right-hand direction and Class 3B fit tolerance\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for consistent dimensional accuracy across production runs\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, clearing the cutting zone in through-hole applications\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction provides higher hardness and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends service life, especially in stainless steel\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3 flutes for progressive thread engagement and controlled torque load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading of 4-48 UNF threads, with a stated material application of stainless steel.

Ensure the workpiece is securely fixtured and the spindle or tapping head is properly aligned before engaging the tap. Use a suitable cutting fluid or tapping compound rated for the workpiece material, particularly when threading stainless steel, to reduce heat buildup and galling. Never reverse-drive a tap without first confirming adequate chip clearance, and inspect the tap for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eThreads per Inch\u003c\/strong\u003e: 48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\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\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.882 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\u003eWeight\u003c\/strong\u003e: 0.025 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3997\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: 9039970028450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730635587890,"sku":"9039970028450","price":47.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13818b0ff8f782969e9f0c743191e66e_5a3653bb-674e-4c19-8986-885b04955249.jpg?v=1788720624","url":"https:\/\/voomisupply.com\/products\/guhring-9039970028450-spiral-point-tap-4-48-unf-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
