With a 0.2559 inch (6.50 mm) cutting diameter, four flutes, and a 30-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action on a wide range of workpiece materials. The WXL finish coating enhances wear resistance and extends tool life in abrasive and harder materials. Centercutting geometry allows for plunge milling in addition to peripheral and slot milling operations. The single-end design is standard for precision CNC and manual mill applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers, vertical mills, and manual knee mills across job shop, tool and die, and production environments. It handles a length of cut up to 0.9449 inches (24.00 mm), making it appropriate for moderate-depth slotting, profiling, and contouring. The 8.00 mm (approximately 0.315 inch) shank diameter and 70.00 mm (approximately 2.756 inch) overall length are typical for compact toolholders and collet chucks used in precision metalworking. Right-hand cut and right-hand flute configuration are standard for conventional CNC spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and thermal stability in hard materials\u003c\/li\u003e\n\u003cli\u003eWXL finish coating for improved wear resistance and tool longevity\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge entry and ramp milling\u003c\/li\u003e\n\u003cli\u003eFour-flute configuration balances chip load capacity with surface finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement solid carbide square end mill for use with standard collet chucks, shrink-fit holders, and weldon-style toolholders accepting an 8.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before inserting or removing the end mill. Seat the shank fully into the toolholder to the recommended gauge line and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a cut, as excessive runout accelerates tool wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2559 inches (6.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.9449 inches (24.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (approximately 0.315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm (approximately 2.756 inches)\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: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: WXL\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.095 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 37420007\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753377005874,"sku":"37420007","price":211.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03aeaa0383091d0c86ad16d7b81f6b36_88a06b9d-e930-462e-88ac-ac9342b8ffb2.jpg?v=1788936000","url":"https:\/\/voomisupply.com\/products\/osg-37420007-square-end-mill-0-2559-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
