The spiral point geometry pushes chips forward ahead of the cutting zone, which reduces chip packing in through-hole tapping applications. Built from high-speed steel (HSS) for durability and heat resistance, the tap features a plug chamfer for general-purpose threading and carries an elektraLUBE coating that lowers friction and extends tool life across high-volume production runs. With 2 flutes and an H7 thread limit, this tap is suited for applications requiring close tolerance fits and consistent thread form.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole tapping in materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The 4-40 UNC thread form is common in precision instrument work, electronics enclosures, and light mechanical assemblies. The plug chamfer makes it adaptable as a starting tap in most standard production setups. It is used primarily by machinists and maintenance professionals in both shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point design pushes chips forward for clean through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eelektraLUBE coating reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit supports close-tolerance thread fits\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction resists heat and wear across a wide material range\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer suitable for general-purpose and production tapping\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole tapping of 4-40 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel.

Always secure the workpiece and ensure proper alignment before beginning the tapping cycle. Power down or de-energize any machine tool before changing or setting tooling. Use appropriate cutting fluid or lubricant for the workpiece material even when the elektraLUBE coating is present, particularly in harder steels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: elektraLUBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5625 inches\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: 105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 2003102\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734829564210,"sku":"2003102","price":34.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da4d98025f1ed84efa20ab6464322202.jpg?v=1788767209","url":"https:\/\/voomisupply.com\/products\/osg-2003102-spiral-point-tap-4-40-unc-hss-elektralube","provider":"Voomi Supply","version":"1.0","type":"link"}
