Built with three flutes, a 0.03-inch corner radius, and an integrated chipbreaker geometry, it breaks chips into smaller segments to reduce heat buildup and cutting forces during heavy cuts. The variable-pitch flute spacing helps suppress chatter and vibration. With a high helix spiral flute design and right-hand cutting direction, it suits high-feed roughing passes on a wide range of workpiece materials. This is a single-end, center-cutting tool intended for use by machinists and toolroom professionals on CNC milling machines and manual mills.\u003c\/p\u003e\u003cp\u003eThe 120669 is suited for roughing applications in job shop, production, and maintenance environments. Its 0.75-inch mill diameter and 0.75-inch straight cylindrical shank fit standard ER and side-lock toolholders sized for 3\/4-inch shanks. The 1.625-inch length of cut accommodates moderate depth-of-cut passes, while the 4-inch overall length keeps the tool rigid in the spindle. The submicron carbide grade and bright uncoated finish make it appropriate for dry or light-coolant roughing where coating adhesion is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChipbreaker geometry reduces chip load and heat in heavy roughing cuts\u003c\/li\u003e\n\u003cli\u003eVariable-pitch flutes suppress chatter and vibration during aggressive passes\u003c\/li\u003e\n\u003cli\u003eHigh helix spiral flute design improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting construction allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide grade provides wear resistance and edge toughness\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of materials and cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for CNC and manual milling machines accepting a 0.75-inch straight cylindrical shank with h6 tolerance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists or toolroom technicians into a compatible milling machine spindle using an appropriate toolholder sized for a 0.75-inch shank. Ensure the machine spindle is fully stopped and the tool changer or drawbar is disengaged before mounting or removing the end mill. Verify toolholder runout before beginning a cut, as excessive runout accelerates edge wear on carbide tooling. Coolant-through is not supported on this tool; use flood or mist coolant directed at the cutting zone if required by the application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.002 to -0.002 inches\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: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Variable\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\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 120669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747729506610,"sku":"120669","price":444.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97554f187cc4efc0d4014dd5f6d58697.jpg?v=1788884762","url":"https:\/\/voomisupply.com\/products\/accupro-120669-roughing-end-mill-3-flute-0-75-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
