With a 0.3543 inch cutting diameter and a 1.1024 inch length of cut, this tool delivers reliable material removal in slots, pockets, and peripheral milling passes. The 0.3937 inch shank diameter provides a secure grip in standard tool holders. A 30-degree helix angle and micrograin carbide substrate combine to produce smooth chip evacuation and a long tool life. The WXL coating enhances wear resistance and thermal protection during high-speed cutting cycles. This end mill is center-cutting and right-hand cut with right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill suits CNC machining centers and manual mills in job shop, tool and die, and general precision machining environments. It is appropriate for cutting ferrous and non-ferrous metals where a fine surface finish and dimensional accuracy are required. The single-end configuration makes it a direct replacement when the tool is worn or broken during production runs. Machinists and CNC operators working in aerospace, automotive, and general manufacturing will find this a capable everyday tool for medium-depth milling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eWXL coating provides wear and heat resistance during high-speed cuts\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eFour flutes deliver a balance of chip clearance and surface finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement square end mill compatible with standard tool holders accepting a 0.3937 inch shank diameter in CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Use a properly sized collet or end mill holder rated for the 0.3937 inch shank and torque the retention nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3543 inches (9 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.1024 inches (28 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80 mm\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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WXL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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 Dimensions\u003c\/strong\u003e: 3.3 x 0.65 x 0.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 37420012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729348165938,"sku":"37420012","price":297.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03aeaa0383091d0c86ad16d7b81f6b36.jpg?v=1788703314","url":"https:\/\/voomisupply.com\/products\/osg-37420012-square-end-mill-0-3543-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
