Built from high-speed steel (HSS) with a bright\/uncoated finish, this tap features a taper chamfer to ease thread entry and a left-hand thread form. The 4-flute straight flute geometry moves chips back along the flute rather than forward, making it suitable for through-hole and blind-hole applications in harder materials. With an overall length of 5.4375 inches and a thread length of 2.5625 inches, this tap is sized for heavy industrial threading work where M30 fastener applications are required.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, maintenance and repair operations, and production environments where large-diameter metric left-hand threads must be cut or restored. Left-hand thread taps are typically selected for applications involving left-hand fasteners, reverse-threaded components, or assemblies that require counter-rotation resistance. The taper chamfer style makes this tap well suited for starting threads from scratch in through-hole work or where gradual thread engagement is preferred. Machinists and toolmakers working with steel, cast iron, and similar ferrous materials will find this tool appropriate for standard machine tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM30x3.50 metric coarse thread form for large-diameter internal threading\u003c\/li\u003e\n  \u003cli\u003eLeft-hand thread direction for reverse-threaded fastener applications\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer for gradual thread engagement and easier tap entry\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip clearance in through-hole and blind-hole work\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in ferrous metal applications\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit for controlled tolerance threading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for machine tapping operations requiring M30x3.50 metric coarse left-hand threads in standard tapping chucks and holders accepting a 1.0210-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed and operated by qualified machinists familiar with tapping speeds, feeds, and cutting fluid requirements for HSS tooling. Ensure the tapping machine or lathe is powered down and properly locked out before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Do not exceed recommended surface speeds for high-speed steel taps in the material being threaded.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.4375 inches (5-7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5625 inches (2-9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.0210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.7660 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: REGAL CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 029261AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REGAL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":67916487033138,"sku":"029261AS","price":312.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53ea93732bc17d80307d7cf87d811580.jpg?v=1791258138","url":"https:\/\/voomisupply.com\/products\/regal-cutting-tools-029261as-straight-flute-tap-m30x3-50","provider":"Voomi Supply","version":"1.0","type":"link"}
