Built on OSG's VG446 series platform, this single-end tool features a 0.5-inch mill diameter, 4 flutes with a variable flute type and 35-degree medium helix angle, and a 0.02-inch chamfer width at a 45-degree chamfer angle. The TiAlN PVD coating provides thermal resistance and wear protection during aggressive cuts in ferrous and difficult-to-machine materials. With an extended reach design and Weldon flat shank, this tool is suited for setups requiring additional projection from the holder without sacrificing rigidity.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where shouldering, slotting, ramp-down entry, helical interpolation, drill milling, and plunging or recessing operations are required. It is rated for primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The extended reach of 2.25 inches and neck diameter of 0.47 inches allow access to deeper features while the 0.625-inch length of cut handles a range of depth-of-cut requirements in both roughing and finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for thermal protection and extended tool life in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003eVariable index, 4-flute geometry reduces chatter during slotting and side milling\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.02-inch chamfer width for consistent edge preparation\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with extended reach supports secure clamping and deep-feature access\u003c\/li\u003e\n  \u003cli\u003eCentercutting capable, supporting plunge entry and drill-mill operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and mills accepting a 0.5-inch Weldon flat shank.

Secure the Weldon flat shank in a properly sized end mill holder or collet before operation and confirm runout is within acceptable tolerance before cutting. Verify spindle speed, feed rate, and depth of cut against OSG published cutting data for the target workpiece material before engaging the cut. Do not exceed the rated reach or apply side loads beyond the tool geometry's intended envelope.\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: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eNeck Diameter\u003c\/strong\u003e: 0.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 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\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0015 inches\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: VG446-5003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754900848946,"sku":"VG446-5003","price":176.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c21c71a6ac290e287a9f25895fccc0bf.jpg?v=1788949646","url":"https:\/\/voomisupply.com\/products\/osg-vg446-5003-corner-chamfer-end-mill-0-5in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
