The spiral point geometry drives chips forward ahead of the cutting flutes, reducing clogging and allowing continuous feed in production and maintenance threading operations. This tap is sized to the 7\/16-20 UNF thread standard, making it suited for fine-pitch fastener work in ferrous and non-ferrous materials. Machinists, tool-and-die technicians, and maintenance professionals reach for plug taps as the standard starting choice for most through-hole tapping jobs.\u003c\/p\u003e\u003cp\u003eThis tap is used in general machine shop, production, and field maintenance environments where fine-thread 7\/16-20 UNF internal threads are required. Typical applications include threading steel, aluminum, brass, and similar machinable materials in through-hole configurations. The plug chamfer — generally 3 to 5 threads of lead — provides a gradual start that guides the tap into the hole without the aggressive engagement of a taper tap or the restricted use-case of a bottoming tap. It is equally at home in manual tap wrenches, hand drills, and machine tapping setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point design pushes chips ahead of the tap, reducing chip packing in through-hole work\u003c\/li\u003e\n\u003cli\u003e7\/16-20 UNF thread form for fine-pitch internal threading\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides hardness and wear resistance across common shop materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer lead suits the majority of standard through-hole tapping applications\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1, available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for any application requiring a 7\/16-20 UNF spiral point plug tap in HSS.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a standard tap wrench, T-handle, or machine tapping setup. Always use the correct tap drill size for 7\/16-20 UNF threads before tapping, and apply cutting fluid appropriate to the workpiece material to extend tool life. Back the tap off periodically during hand tapping to break chips. Inspect the tap for chipping or wear before reuse to avoid thread damage or tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Spiral Point Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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-4375-20-P-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233498169650,"sku":"SP-4375-20-P-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307624366.png?v=1780101464","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-sp-4375-20-p-i-7-16-20-hss-spiral-point-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
