This single-end tool features a 0.4375 inch (7\/16 inch) cutting diameter, a 2 inch length of cut, and a 4.5 inch overall length. It carries a FIREX coating, a multi-layer physical vapor deposition finish that extends tool life when cutting ferrous materials. The variable helix geometry reduces vibration and chatter during cuts. With four flutes and a right-hand spiral configuration, it is suited for finishing and semi-finishing passes where surface quality and tool stability matter. Licensed machinists and CNC operators in job shops and production facilities are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for milling cast iron and steel as primary workpiece materials, with secondary capability in hard materials, stainless steel, and high-temperature alloys. The long-series length type provides extended reach for deep pocket milling, slotting, and profiling operations where a standard-length tool cannot access the feature. The straight cylindrical shank with h6 tolerance fits standard ER collet chucks and side-lock holders. The FIREX coating and variable helix make it particularly effective on materials that generate high cutting temperatures or cause built-up edge on uncoated tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and hard material applications\u003c\/li\u003e\n  \u003cli\u003eFIREX multi-layer coating extends tool life in high-heat cutting conditions\u003c\/li\u003e\n  \u003cli\u003eVariable helix flute geometry reduces harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eFour-flute, right-hand spiral, right-hand cut configuration for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eLong-series overall length (4.5 inches) with 2 inch length of cut for deep-feature reach\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable — suitable for plunge entry as well as peripheral milling\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with h6 tolerance for precise collet or side-lock chuck fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the GUHRING Series 4250. Designed for use in CNC machining centers and manual mills equipped with ER collet chucks or other holders accepting a 0.4375 inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel (ISO material codes K and P); secondary workpiece materials include hard materials, stainless steel, and high-temperature alloys (ISO codes H, M, and S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in an e-stop or tool-change state. Seat the shank fully into the collet or holder to the recommended gauge length before torquing the retention nut to the holder manufacturer specification. Inspect the cutting edges and coating for chips or damage before each use — do not run a damaged carbide tool. Verify spindle speed and feed rate parameters in the CAM program or operator sheet match the tool diameter and workpiece material before initiating the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel (ISO K, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material, Stainless Steel, High-Temperature Alloys (ISO H, M, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9042500111100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727135080754,"sku":"9042500111100","price":185.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/913b67042303736a9eeed6cf0ad4cfa7.jpg?v=1788673885","url":"https:\/\/voomisupply.com\/products\/guhring-9042500111100-square-end-mill-0-4375-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
