Built from vanadium high-speed steel (HSS-E) and finished with a steam oxide coating, this tap is engineered for controlled chip ejection in through-hole threading operations. It carries an H2 thread limit and suits Class 2B and 3B fits. The two-flute spiral point geometry pushes chips forward ahead of the cutting zone, making it well-suited for production tapping in through holes where chip packing is a concern. Overall length is 1.937 inches, with a thread length of 0.299 inches and a shank diameter of 0.141 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in through-hole tapping applications across a broad range of metalworking environments, from job shops to production lines. The steam oxide finish reduces friction and provides modest lubrication retention during the cut. The H2 thread limit and 2B\/3B class of fit make it appropriate for standard fastener thread tolerances in general mechanical assemblies. Material compatibility covers aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, cast iron, and hardened steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-40 UNC thread form with H2 thread limit and 2B\/3B class of fit\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral point geometry pushes chips forward for use in through holes\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel (HSS-E) construction for wear resistance across a wide range of work materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and improves lubrication retention\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for standard entry and full thread engagement over the first few threads\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style cutting tool for through-hole 5-40 UNC threading operations in materials including aluminum, stainless steel, alloy steel, die steel, cast iron, and low-, medium-, and high-carbon steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a compatible tap holder or CNC tapping chuck sized for a 0.141-inch shank diameter. Power down or disable the machine spindle before loading or changing tooling. Use appropriate cutting fluid for the work material — the steam oxide finish assists but does not replace proper lubrication. Follow shop-standard speeds and feeds for HSS taps in the target material; exceeding recommended parameters will accelerate wear or cause breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eMaterial\u003c\/strong\u003e: 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\u003eOverall Length\u003c\/strong\u003e: 1.937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.299 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 2807001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736755274034,"sku":"2807001","price":36.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/829bf59e45ba7a342add6840f6347873.jpg?v=1788779965","url":"https:\/\/voomisupply.com\/products\/osg-2807001-spiral-point-tap-5-40-unc-2-flutes-h2-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
