Also called a gun tap, the spiral point pushes chips ahead of the cutting edge rather than packing them into the flute, making it well suited for through-hole tapping. The tap is ground from 3% vanadium high-speed steel (HSS-E) for improved wear resistance over standard M2 HSS and is finished with a steam oxide coating that provides light lubricity and corrosion resistance during storage and use. The H2 thread limit holds close tolerances compatible with 2B and 3B class-of-fit specifications. With a 2-inch overall length and a 0.141-inch shank diameter, the 2807601 fits standard tap holders and machine spindles used in both manual and CNC tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is appropriate for production and maintenance tapping in metalworking shops, machine shops, and field repair environments. The 6-40 UNF thread size is common in instrument hardware, electrical connectors, small fastener assemblies, and precision mechanical components. The 2-flute plug chamfer geometry provides a gradual lead-in of roughly 3 to 5 threads, balancing cutting load and thread quality. Stated material applications include aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron, giving the tool broad utility across general metalworking. Right-hand cutting direction is standard for conventional 6-40 UNF fastener threads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point (gun tap) geometry pushes chips forward through the hole, reducing chip packing in through-hole applications\u003c\/li\u003e\n  \u003cli\u003e3% vanadium HSS-E construction delivers higher wear resistance compared to standard M2 high-speed steel\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating provides light lubricity and protects the tap during storage\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit ensures compatibility with 2B and 3B class-of-fit tolerances\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 2 flutes offers a balanced entry lead for both hand and machine tapping\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies use in standard tap holders without internal coolant supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe OSG 2807601 is designed as a standard replacement or production tap for any application requiring a 6-40 UNF 2B or 3B class-of-fit internal thread. Compatible material applications stated by the manufacturer include aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and operated by a machinist or tool and die technician using a standard tap wrench, tapping head, or CNC rigid tapping cycle. Before tapping, ensure the workpiece is secured and the correct drill size for a 6-40 UNF thread has been used to prepare the pilot hole. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread finish. Do not reverse the tap under load without breaking the chip; back off periodically when hand tapping to clear chips from the cutting zone.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B \/ 3B\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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.6875 inches (11\/16 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\u003eMaterial\u003c\/strong\u003e: 3% Vanadium High-Speed Steel (HSS-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 280\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2807601\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743943262514,"sku":"2807601","price":31.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6050b2b59cd463b64dec318f4ddb755c.jpg?v=1788851692","url":"https:\/\/voomisupply.com\/products\/osg-2807601-spiral-point-tap-6-40-unf-2-flute-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
