Built to Series 524 long-series specifications, it carries a 1\/16 inch (1.59 mm) mill diameter with four flutes and an AlTiN coating that improves heat resistance and extends tool life in demanding cutting conditions. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece as well as cut along the periphery. Machinists and tool-and-die professionals working on CNC mills, VMCs, and manual knee mills will find this tool suited to fine-detail and tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis end mill is configured for right-hand cutting with a right-hand spiral flute and a straight 1\/8 inch shank. The long-series overall length of 2.5 inches provides extended reach into deep pockets, slots, and contoured features where a standard-length tool cannot access. The 5\/16 inch length of cut accommodates moderate depth-of-cut passes while maintaining rigidity at this small diameter. It is primarily rated for steel (ISO material code P) and is well suited for mold work, die work, and general-purpose ferrous machining where fine feature definition is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance at 1\/16 inch diameter\u003c\/li\u003e\n\u003cli\u003eAlTiN coating enhances heat resistance and reduces friction during dry or semi-dry cutting in steel\u003c\/li\u003e\n\u003cli\u003eFour-flute design improves surface finish and feed-rate capability compared to two-flute alternatives\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral helix promotes efficient chip flow out of the cut zone\u003c\/li\u003e\n\u003cli\u003eLong-series length of 2.5 inches provides extended reach for deep-pocket and contour work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a fractional-inch series replacement and general-purpose end mill for CNC and manual milling machines accepting a 1\/8 inch straight shank; primary workpiece material rating is steel (ISO code P).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall this end mill in a collet or end-mill holder rated for 1\/8 inch straight shanks; ensure the holder is clean and free of debris before seating the tool. Power down and lock out the spindle before any tool change. At 1\/16 inch diameter, this tool is sensitive to runout — verify holder and spindle runout with a dial indicator before cutting to avoid premature breakage. Feed and speed parameters should be established from the manufacturer's published data for AlTiN-coated carbide in the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches \/ 1.59 mm)\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inch (0.3125 inches \/ 7.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches \/ 3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (63.5 mm)\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\u003eShank Type\u003c\/strong\u003e: Straight\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 524\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14981768\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732689846578,"sku":"14981768","price":46.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_48e2fc72-07ca-43cc-ba10-febad86c6e13.jpg?v=1788745748","url":"https:\/\/voomisupply.com\/products\/accupro-14981768-1-16-in-4-flute-carbide-square-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
