With a 0.125 inch (1\/8 inch) cutting diameter and a 40-degree helix angle, it delivers aggressive chip evacuation and smooth cutting action. The diamond-like carbon (DLC) finish reduces friction and improves wear resistance in high-speed applications. Three flutes provide a balance between chip clearance and surface finish quality. This end mill is centercutting, allowing plunge entry directly into the workpart. It is a single-end tool intended for CNC machining centers and manual mills operated by machinists and tool-and-die technicians.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, profiling, and contouring operations in light to medium-duty applications. The 3\/8 inch length of cut accommodates shallow to moderate depth passes, making it appropriate for precision work in mold making, prototype machining, and general-purpose shop use. Right-hand cut with right-hand flute orientation is standard for conventional CNC spindle configurations. The 1\/8 inch shank diameter fits standard collets and tool holders commonly used in small-diameter machining setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eDLC finish reduces friction and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eThree-flute design balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills using 1\/8 inch collets or tool holders accepting a 0.125 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard tool-holding procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the collet or chuck. Use a calibrated torque wrench on collet nuts and verify tool runout with a dial indicator before beginning production cuts. Do not exceed the recommended depth of cut for the tool diameter to avoid tool deflection or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.7 x 0.45 x 0.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 86300009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747980280114,"sku":"86300009","price":48.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/322fbfd5a2320cf18d0879c8cc2aed35_c1c42054-2626-4e61-a44e-8cf56530021a.jpg?v=1788887687","url":"https:\/\/voomisupply.com\/products\/osg-86300009-square-end-mill-1-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
