The set pairs a 4.0 x 0.75 metric plug tap with a number 30 drill bit, giving technicians the correct clearance drill and tap in a single package. The tap features precision-cut, accurately formed threads for consistent, repeatable thread profiles. Both tools are heat treated and tempered to file-hard hardness, extending service life under regular hand-tapping workloads. Packaged as a 2-piece set, this combo reduces the risk of mismatched tooling on the job.\u003c\/p\u003e\n\u003cp\u003eThis combo pack is suited for maintenance, repair, and fabrication work where metric M4 x 0.75 threads are required. Typical applications include tapping threads in sheet metal, brackets, enclosures, and light structural components. The plug tap style makes it appropriate for through-holes and partially blind holes where a starting taper is not required. It is commonly used by HVAC technicians, electricians, plumbers, and general trade professionals who need to add or restore metric fastener threads in the field or shop.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.0 x 0.75 metric plug tap paired with a matching number 30 drill bit for correct thread clearance\u003c\/li\u003e\n  \u003cli\u003ePrecision-cut threads accurately formed for consistent, exact threading results\u003c\/li\u003e\n  \u003cli\u003eHeat treated and tempered to file-hard hardness for extended tool life\u003c\/li\u003e\n  \u003cli\u003ePlug-style tap designed for hand cutting applications in through-holes and partial blind holes\u003c\/li\u003e\n  \u003cli\u003e2-piece combo pack keeps drill and tap together to prevent mismatched tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand-tapping M4 x 0.75 metric threaded holes in typical trade and fabrication applications where a plug-style tap is appropriate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap set is intended for hand cutting use with a standard tap handle or T-handle wrench. Always drill the clearance hole with the included number 30 bit before tapping. Secure the workpiece firmly and apply appropriate cutting fluid to extend tap life and improve thread quality. Never force the tap against hard resistance; back off periodically to break chips and prevent breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4.0 x 0.75 metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: No 30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Hand cutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: CENTURY DRILL TOOL CO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 97507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51558626197810,"sku":"97507","price":16.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/061e287c85f4ef3f98b2e8ff0211140a_29dc4ed7-3602-403a-af8d-1ad9c8879800.jpg?v=1786416308","url":"https:\/\/voomisupply.com\/products\/century-drill-tool-97507-4-0x0-75-tap-no-30-bit-combo-2pc","provider":"Voomi Supply","version":"1.0","type":"link"}
