The spiral point geometry drives chips forward ahead of the cutting flutes, reducing clogging and allowing smooth through-hole tapping. Built from HSS, this tap offers the hardness and wear resistance needed for production threading in ferrous and non-ferrous materials. It is a standard import-grade tool suited for use in manual tap handles, tap wrenches, or CNC tapping cycles on light machine setups.\u003c\/p\u003e\u003cp\u003eThis tap covers the 4-40 thread standard, a fine unified national coarse (UNC) designation common in small-fastener applications such as electronics enclosures, instrument panels, and precision assemblies. It is appropriate for through-hole tapping in sheet metal, aluminum, brass, mild steel, and similar materials. Machinists, tool-and-die makers, maintenance technicians, and production operators typically deploy this size in benchtop drill press work or hand-tapping fixtures where small thread profiles are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 thread form for small-fastener and fine-pitch applications\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward for cleaner through-hole tapping\u003c\/li\u003e\n\u003cli\u003eHSS construction provides hardness and wear resistance across common workpiece materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer style allows entry into through holes and partially started threads\u003c\/li\u003e\n\u003cli\u003eCompatible with standard tap handles, T-wrenches, and CNC tapping attachments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 plug tap for use in through-hole tapping operations across common metalworking and fabrication setups.

Always secure the workpiece firmly and align the tap perpendicular to the drilled pilot hole before beginning the cut. Back the tap off periodically to break chips and clear the cutting zone. Handle HSS taps with care to avoid chipping the flutes, as they are brittle under lateral loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Style\u003c\/strong\u003e: Spiral Point Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SP-440-P-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51234037694770,"sku":"SP-440-P-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307624365.png?v=1780115845","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-sp-440-p-i-4-40-hss-spiral-point-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
