With a 0.4375 inch (7\/16 inch) mill diameter, 4 flutes, and a stub-length profile, this end mill delivers rigid performance in shallow-to-moderate depth cuts. The Duarise coating reduces friction and extends tool life in demanding materials. Variable helix and variable index geometry help suppress chatter and improve surface finish. Micrograin carbide construction provides the hardness and edge retention needed for high-speed cutting in ferrous and non-ferrous materials. This is a single-end, centercutting tool with right-hand cut and right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThe OSG 82300621 is suited for CNC machining centers and manual mills in job shop, toolroom, and production environments. The stub length and 0.4375 inch shank diameter make it a practical choice for side milling, slotting, and profiling operations where rigidity is a priority. The straight flute design is appropriate for applications where axial cutting forces need to be minimized. This tool is installed and operated by machinists and CNC operators working to standard machining tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eDuarise coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry suppress chatter and improve surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry\u003c\/li\u003e\n\u003cli\u003eStub length profile maximizes rigidity in shallow-cut applications\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.0000 \/ -0.0008 inches for precise fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 7\/16 inch collet or end mill holder tooling systems.

Secure the shank fully in a matched collet or end mill holder and torque to the toolholder manufacturer's specifications. Ensure the spindle and machine are powered down and locked out before changing tooling. Verify runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5469 inches (35\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Duarise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8230\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: 82300621\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51745963278642,"sku":"82300621","price":162.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/441647a8da8829deeaa170baa6eb5f12_0579dbba-402d-4bca-99d3-e1f4485de5cb.jpg?v=1788866079","url":"https:\/\/voomisupply.com\/products\/osg-82300621-square-end-mill-7-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
