Part of the GUHRING Series 3078, this single-end mill features a variable helix design with flute angles ranging from 40 to 42 degrees, which reduces harmonic vibration and chatter during aggressive cuts. It carries a FIREX finish, a multi-layer PVD coating that provides elevated heat resistance and extended tool life in dry or near-dry cutting conditions. With a 0.75-inch cutting diameter and a 1.5-inch length of cut, this tool is suited for slotting, profiling, and peripheral milling on CNC machining centers.\u003c\/p\u003e\u003cp\u003eThe 9030780190500 is intended for machinists and CNC programmers working with stainless steel, alloy steel, and cast iron in production and job-shop environments. The Weldon flat shank diameter matches the 0.75-inch cutting diameter, providing a secure, anti-pullout grip in side-lock toolholders. The centercutting geometry allows plunge entry without a pre-drilled hole, supporting ramping and helical interpolation strategies. This tool is classified under ISO material groups P, M, K, and S, covering carbon steel, stainless steel, cast iron, and certain high-temperature alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix at 40 and 42 degrees reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eFIREX multi-layer PVD coating for extended tool life in stainless and alloy steel\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge and ramping entry\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides anti-pullout retention in side-lock holders\u003c\/li\u003e\n\u003cli\u003eSpiral flute geometry with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker — suited for continuous finishing and semi-finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with 0.75-inch side-lock or Weldon-style toolholders.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the Weldon flat against the setscrew in the toolholder and torque the setscrew to the toolholder manufacturer specification — do not rely on feel alone. Verify runout with a dial indicator before beginning a production run, as excessive runout accelerates flute wear on solid carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 to 42 degrees (variable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3078\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9030780190500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747614261554,"sku":"9030780190500","price":454.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be5fa771cc3e4ebe7bf075c70a0bd6f1_aeb70f67-047a-48d6-bfd6-3136fee32672.jpg?v=1788883481","url":"https:\/\/voomisupply.com\/products\/guhring-9030780190500-square-end-mill-0-75in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
