Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS cannot match. The cutter measures 1.5 inches in diameter with a 3-inch length of cut, a 1.25-inch shank diameter, and a 5.5-inch overall length. Four spiral flutes with a 30-degree right-hand helix generate efficient chip evacuation and smooth cutting action across a wide range of ferrous and non-ferrous workpiece materials. This is a single-end, centercutting tool suitable for slotting, profiling, and plunging operations. It ships bright and uncoated.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. The 1.25-inch shank fits standard R8, CAT, BT, and direct-mount toolholders of the appropriate bore. Typical applications include profile milling, shoulder milling, and full-slot cutting on vertical mills, horizontal mills, and CNC machining centers. The regular-length geometry and 3-inch length of cut give machinists adequate reach for most medium-depth cavity and pocket work without sacrificing rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance versus standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e1.5-inch cutting diameter with 3-inch length of cut for medium-depth slotting and profiling\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes at 30-degree right-hand helix for efficient chip flow and smooth finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — compatible with regrinding services and standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eSingle-end construction; OSG Series 548 regular-length geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool compatible with any machine spindle or toolholder accepting a 1.25-inch round shank, including standard milling chucks, collet holders, and side-lock holders. Primary workpiece material codes P, M, K, S, N, and H are supported per the manufacturer specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified CNC operator should install and set this tool. Power down and lock out the spindle drive before loading or changing the cutter. Seat the shank fully in the toolholder and torque the retention hardware to the toolholder manufacturer's specification. Verify runout with a dial indicator before cutting, and confirm that cutting fluid or air blast is directed at the flutes to prevent chip re-cutting and premature edge wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 548\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy, Aluminum and Non-Ferrous, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 5486200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728462315826,"sku":"5486200","price":302.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a8dc006b1ec01ed404cacbfb9693fa9.jpg?v=1788691587","url":"https:\/\/voomisupply.com\/products\/osg-5486200-square-end-mill-1-5in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
