Part of the Series 4252 lineup, this single-end mill features a variable helix geometry with angles ranging from 35 to 38 degrees, reducing harmonic vibration and improving surface finish during cuts. At 0.5 inches in diameter with a 3-inch length of cut and 5-inch overall length, it is built for extra-long reach operations where standard-length tooling falls short. The FIREX coating provides enhanced thermal resistance and wear protection, extending tool life in abrasive and hard materials. Installation is performed by machinists on CNC milling centers or manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling cast iron, steel, stainless steel, and hard materials in both roughing and finishing passes. The centercutting design allows plunge entry, and the right-hand spiral flute with right-hand cut orientation makes it compatible with standard spindle setups. The Weldon flat shank provides positive drive and resistance to pullout under high feed rates. Its extra-long length of cut makes it well matched for deep-pocket milling, slot milling, and profile work where reach is a primary concern. It is appropriate for production environments handling medium to high hardness ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix angles of 35 and 38 degrees reduce chatter and improve chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFIREX coating improves thermal and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank resists pullout under aggressive feed conditions\u003c\/li\u003e\n  \u003cli\u003eExtra-long 3-inch length of cut supports deep-pocket and extended-reach operations\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and edge retention superior to HSS tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 0.5-inch collet chucks, end mill holders, or Weldon-style side-lock holders on CNC machining centers and manual mills.

Ensure the spindle is fully stopped and machine power is locked out before inserting or removing the end mill. Seat the Weldon flat against the set screw in the holder and tighten to the tool holder manufacturer's specification to prevent axial pullout. Verify runout with a dial indicator before initiating cutting operations, especially at extended reach.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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: 3 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: 0.5 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\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Helix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: Extra Long\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\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: 4252\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.196 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: 9042520127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748199432498,"sku":"9042520127000","price":269.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/805eb793cfe65a9b122f9a9a51ad8bb6_0625a7b8-82dd-4641-a5a3-8cfe65d7ffcd.jpg?v=1788890235","url":"https:\/\/voomisupply.com\/products\/guhring-9042520127000-square-end-mill-0-5in-4f-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
