Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for aggressive cutting passes. The 1\/4 inch diameter tool features 3 spiral flutes with an integrated chipbreaker geometry that breaks chips into shorter segments, reducing heat buildup and improving chip evacuation at the cut. A high-helix flute design promotes efficient chip flow. This end mill is center-cutting and designed for right-hand cutting and flute direction. Licensed machinists and CNC operators typically run this tooling in machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThe 120653 suits roughing operations in ferrous and non-ferrous metals, plastics, and composites where material removal rate takes priority over surface finish. The 3\/4 inch length of cut and 2-1\/2 inch overall length make it appropriate for shallow-to-medium-depth pocketing, slotting, and profile roughing. The bright, uncoated finish makes it straightforward to inspect for wear between passes. The 1\/4 inch shank with an h6 tolerance fits standard collet chucks and end mill holders without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for extended tool life under heavy cutting loads\u003c\/li\u003e\n  \u003cli\u003eIntegrated chipbreaker geometry reduces chip length and lowers cutting forces during roughing passes\u003c\/li\u003e\n  \u003cli\u003eHigh-helix spiral flute design promotes efficient chip evacuation from the cut zone\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and flute direction; compatible with standard CNC and manual milling setups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish simplifies visual wear inspection between operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 1\/4 inch collet chucks and end mill holders on CNC machining centers and manual vertical mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Confirm the spindle is fully stopped and the machine is locked out before changing tooling. Seat the 1\/4 inch shank fully into a clean, undamaged collet or end mill holder and torque the retention mechanism to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, and confirm chip evacuation is adequate for the selected feed and speed parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35 mm)\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: 3\/4 inch (0.7500 inch \/ 19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Submicron-grade solid carbide\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: +0.0000 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\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 120653\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753094021426,"sku":"120653","price":90.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/525f22f2a0e6b6b115c192e22f87a028.jpg?v=1788932744","url":"https:\/\/voomisupply.com\/products\/accupro-120653-roughing-end-mill-1-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
