It features a 1 inch cutting diameter, a 3.125 inch length of cut, and a 6 inch overall length, placing it in the extra-long length category for extended reach requirements. The FIREX coating provides high heat resistance and reduces friction at the cutting edge. A variable helix design with 35 and 38 degree helix angles minimizes chatter and promotes smooth chip evacuation. Four right-hand spiral flutes and a center-cutting geometry allow plunge, slot, and profile milling operations. This tool is intended for use by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on cast iron, steel, stainless steel, and hard materials in both horizontal and vertical machining centers. The extra-long length of cut makes it appropriate for deep cavity work, tall workpiece features, and applications where standard-length tools cannot reach. The Weldon flat shank with a 1 inch diameter provides positive drive and is compatible with standard Weldon-style end mill holders. The Series 4252 designation identifies this as part of a GUHRING high-performance end mill family optimized for aggressive feed rates in tough ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFIREX coating for elevated heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eVariable helix at 35 and 38 degrees reduces harmonic vibration during cutting\u003c\/li\u003e\n\u003cli\u003eExtra-long 3.125 inch length of cut for deep cavity and tall-feature milling\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry enables direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for secure, positive drive in standard end mill holders\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability at elevated cutting speeds\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 on CNC vertical and horizontal machining centers.

Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing tooling. Seat the Weldon flat against the setscrew in the holder and torque the setscrew per the holder manufacturer specification. Confirm runout with a dial indicator before beginning a production cut, particularly given the extra-long length of cut which amplifies deflection if the tool is not properly seated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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\u003eHelix Angle\u003c\/strong\u003e: 35 and 38 degrees (variable)\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\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\u003eCenter Cutting\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.411 pounds\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: 9042520254000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749415977266,"sku":"9042520254000","price":825.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/805eb793cfe65a9b122f9a9a51ad8bb6_1d0c8b78-856c-46df-a96e-5560ea1d113c.jpg?v=1788905811","url":"https:\/\/voomisupply.com\/products\/guhring-9042520254000-square-end-mill-1-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
