It features a 3\/8 inch cutting diameter, a 1.5 inch length of cut, and a 4 inch overall length, making it well-suited for slotting, profiling, and peripheral milling. The 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces. A diamond-like carbon (DLC) finish is applied to improve surface hardness and extend tool life. This end mill is centercutting, allowing direct plunge entry into the workpiece. It is installed and operated by machinists and CNC tooling professionals in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThe OSG 86300909 is intended for use in CNC machining centers and manual milling machines where a standard 3\/8 inch shank toolholder or collet is used. The right-hand cut and right-hand flute configuration is the standard orientation for conventional and climb milling. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. This tool is commonly selected for finishing and semi-finishing passes on ferrous and non-ferrous materials where a DLC coating provides a performance advantage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch cutting diameter with matching 3\/8 inch shank diameter for direct collet mounting\u003c\/li\u003e\n  \u003cli\u003e1.5 inch length of cut supports moderate-depth slotting and profiling operations\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip flow and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eDLC finish increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate supports elevated cutting speeds and extended tool life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8 inch shank toolholders, collet chucks, and end mill holders on CNC machining centers and conventional knee mills.

Power down and lock out the spindle before mounting or removing the end mill. Seat the shank fully into the collet or toolholder and torque the retention hardware according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut, as excessive runout will reduce tool life and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 4.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\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: 86300909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732092911922,"sku":"86300909","price":111.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/322fbfd5a2320cf18d0879c8cc2aed35_0df68b8b-5f26-47b0-b739-7f8862880a48.jpg?v=1788739112","url":"https:\/\/voomisupply.com\/products\/osg-86300909-square-end-mill-3-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
