It features a variable index geometry combined with a chipbreaker (nicked) flute profile, which breaks up long chips and reduces cutting forces during aggressive material removal passes. The 1\/2-inch mill diameter pairs with a 1\/2-inch straight-cylindrical shank for direct fit in standard collets and end mill holders. Applied EXO coating enhances surface hardness and heat resistance. This tool is installed and operated by CNC machinists, tool-and-die professionals, and precision machining technicians.\u003c\/p\u003e\n\u003cp\u003eThe VGM5-2130 is suited for milling ferrous and non-ferrous metals in both roughing and semi-finishing operations on vertical and horizontal machining centers. The chipbreaker geometry makes it particularly effective in deep-pocket and full-width slot milling where chip evacuation is critical. The 1-inch length of cut and regular-length body fit standard tool-length setups without requiring extended-reach adapters. The 40-degree helix angle promotes smooth cutting action and stable tool engagement across a range of workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eChipbreaker (nicked) flute profile breaks chips and reduces cutting forces in aggressive passes\u003c\/li\u003e\n  \u003cli\u003eVariable index geometry minimizes chatter and vibration during high-feed milling\u003c\/li\u003e\n  \u003cli\u003eEXO coating provides elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e5-flute configuration increases feed rate capability compared to 4-flute designs\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip flow and stable engagement\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement within the OSG VGM5-NIK series.

Secure the shank fully within the holder to the recommended gauge length and verify runout with a dial indicator before cutting. Confirm spindle and coolant systems are off and the machine is in a safe state before tool changes. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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: EXO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Chipbreaker\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\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: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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 \/ -0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VGM5-NIK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.269 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: VGM5-2130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746563457330,"sku":"VGM5-2130","price":125.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fde0481c45bf480ac8edd6c7a80f1382_cf694ef8-401a-4fe3-baf5-77e882347d28.jpg?v=1788871339","url":"https:\/\/voomisupply.com\/products\/osg-vgm5-2130-variable-geometry-end-mill-1-2-inch-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
