It features a 1-inch cutting diameter, a 5-1\/2-inch length of cut, and a 37-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. Three right-hand spiral flutes deliver a balance of rigidity and material removal across a range of peripheral and slot milling applications. The micrograin carbide substrate provides hardness and edge retention suited to demanding production environments. This tool is installed and operated by machinists and tool-and-die professionals working on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for deep-reach milling applications where a standard-length tool cannot access the full depth of a workpiece feature. The 8-inch overall length and 5-1\/2-inch length of cut make it appropriate for slotting, profiling, and pocket milling where extended reach is required. The bright\/uncoated finish makes it a practical choice for aluminum, copper alloys, and other non-ferrous materials where coated tools may cause built-up edge. The center-cutting geometry also allows plunge entry when the operation requires it.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch mill diameter with a tight tolerance of +0.000 \/ -0.005 inches for accurate fitment in collets and tool holders\u003c\/li\u003e\n\u003cli\u003e5-1\/2-inch length of cut enables deep-reach profiling and slotting operations\u003c\/li\u003e\n\u003cli\u003e37-degree right-hand helix angle promotes smooth chip flow and reduces chatter at the cutting edge\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers edge retention and resistance to deflection under load\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish is well-suited to non-ferrous and softer workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 1-inch straight shank with a shank diameter tolerance of +0.0001 \/ -0.0004 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by qualified machinists following standard toolholding procedures for collet chucks, end mill holders, or hydraulic chucks rated for 1-inch shank diameters. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout within acceptable limits before beginning a cut, as extended-reach tools are more sensitive to spindle and holder runout than stub-length tools. Follow the machine manufacturer and tooling manufacturer guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 315101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739282604338,"sku":"315101","price":1202.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cefce5efb7c3d91447fe6143a2831677_9ef18508-047e-4d7a-b500-545592e1e0ba.jpg?v=1788812665","url":"https:\/\/voomisupply.com\/products\/accupro-315101-square-end-mill-1-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
