With a 1 inch cutting diameter, a 2.25 inch length of cut, and a 5 inch overall length, this tool is built for rigidity and precision. It features a FIREX coating for extended tool life in abrasive and high-temperature cutting conditions. The variable helix spiral flute geometry reduces chatter and improves chip evacuation. Installation and use are handled by machinists and CNC operators working with vertical or horizontal milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing and finishing operations in steel, cast iron, stainless steel, and hard materials. The 4-flute, right-hand spiral flute design provides efficient chip removal and surface finish quality across a range of material grades. The Weldon flat shank with a 1 inch shank diameter provides secure tool holding and minimizes pullout risk in heavy-cut scenarios. This is a single-end, center-cutting tool, meaning it can be used for both peripheral milling and direct plunge entry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with h10 mill diameter tolerance for consistent fit\u003c\/li\u003e\n\u003cli\u003eFIREX coating for heat and wear resistance in ferrous and hard material applications\u003c\/li\u003e\n\u003cli\u003eVariable helix design reduces vibration and chatter during cutting\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with center-cutting capability for plunge entry\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank with h6 shank diameter tolerance for secure tool holder engagement\u003c\/li\u003e\n\u003cli\u003eNo coolant-through — designed for external coolant or dry machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1 inch Weldon-style end mill holders.

Confirm runout with a dial indicator before beginning the cut. Ensure the milling machine spindle and tool holder are clean and free of debris before seating the shank. Follow the machine manufacturer and GUHRING Series 4250 application guidelines for appropriate feed, speed, and depth-of-cut parameters for the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material, Stainless Steel\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: 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: 9042500254000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729272570162,"sku":"9042500254000","price":773.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/913b67042303736a9eeed6cf0ad4cfa7_bb2160e3-dfd2-4672-b125-769867f919e9.jpg?v=1788702357","url":"https:\/\/voomisupply.com\/products\/guhring-9042500254000-square-end-mill-1-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
