Built from high-speed steel (HSS) with a bright uncoated finish, this 4-flute tap delivers consistent thread geometry in a range of metalworking applications. The plug chamfer style provides a gradual lead-in with several partial threads at the start, making it suitable for through-hole tapping where the tool can pass completely through the workpiece. The tap carries a Class of Fit designation of 6H and a Thread Limit of D9, ensuring threads fall within standard tolerance for metric fastener fitment. Overall length is 5.44 inches, with a thread length of 2.563 inches.\u003c\/p\u003e\u003cp\u003eThis hand tap is used in machine shops, maintenance facilities, and production environments where M30 metric coarse threads are required. It is suited for tapping cast iron and non-ferrous metals, as indicated by the manufacturer material application data. The straight-flute design makes it appropriate for through-hole applications and for use in materials that produce short, brittle chips. It is intended for hand tapping operations or low-speed machine tapping setups where controlled feed and chip management are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM30x3.50 Metric Coarse thread form for standard metric fastener compatibility\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across cast iron and non-ferrous metal workpieces\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (partial thread lead-in) suits through-hole tapping applications\u003c\/li\u003e\n\u003cli\u003e4-flute straight-flute geometry supports chip control in brittle materials\u003c\/li\u003e\n\u003cli\u003e6H Class of Fit and D9 Thread Limit meet standard metric tolerance requirements\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup affecting thread dimension accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for M30x3.50 Metric Coarse through-hole tapping in cast iron and non-ferrous metal workpieces.

Always secure the workpiece fully before beginning the tapping operation, and use the appropriate tap wrench or tapping attachment sized for the shank diameter. Apply a suitable cutting fluid for the workpiece material to reduce heat and extend tool life. Back the tap out periodically to break and clear chips during deep or blind-hole applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M30x3.50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\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\u003eClass of Fit\u003c\/strong\u003e: 6H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: D9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight Flute\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.563 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.021 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4130578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750782533938,"sku":"4130578","price":608.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d33fd9d0c04b3be85c3214ba6ffffccf.jpg?v=1788919633","url":"https:\/\/voomisupply.com\/products\/kennametal-4130578-m30x3-50-hand-tap-plug-rh-6h-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
