Built from micrograin solid carbide and coated with AlCrTiN for heat and wear resistance, this tool handles high-speed cutting in hardened steels, stainless steels, and other difficult materials. It features a 3\/4 inch diameter, a 3-1\/4 inch length of cut, and a 38-degree helix angle with 7 flutes for improved chip evacuation and surface finish. The right-hand flute direction and right-hand cutting direction make it compatible with standard CNC machining centers and manual mills. This tool is installed and set up by machinists and tooling specialists in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for deep-cavity milling, profiling, and finishing passes where corner radius geometry reduces stress concentration and extends tool life. The 6 inch overall length provides extended reach for deeper pockets and tall workpiece features. The straight-cylindrical shank with a 3\/4 inch diameter seats securely in standard end mill holders and collet chucks. Its noncentercutting design means it is intended for peripheral and slot milling rather than direct plunge operations. It belongs to the ACCUPRO Series HS lineup, targeting high-performance roughing and finishing applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrTiN coating provides thermal barrier and oxidation resistance for extended tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers hardness and rigidity for tight-tolerance work\u003c\/li\u003e\n  \u003cli\u003e7-flute design increases feed rates and improves surface finish compared to standard 4-flute tools\u003c\/li\u003e\n  \u003cli\u003e0.120 inch corner radius reduces corner chipping and stress concentration at workpiece edges\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes smooth cutting action and efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eNoncentercutting geometry suited for peripheral milling, profiling, and finishing passes\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with straight-cylindrical shank for use in standard end mill holders and collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with standard 3\/4 inch end mill holders, collet chucks, or milling adapters accepting a straight-cylindrical shank.

Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool. Seat the shank fully into the holder to the recommended gauge line and torque the retention hardware per the holder manufacturer specifications. Because this is a noncentercutting end mill, do not use it for direct axial plunge cuts; ramp or helical entry is required when entering closed pockets.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3-1\/4 inches (3.2500 inches \/ 82.55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.120 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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: AlCrTiN\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\u003c\/strong\u003e: 3\/4 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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: No\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\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: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\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: 312777\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731079889202,"sku":"312777","price":330.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d65f8b895eb0617509e51640a2ceb153_9038132e-5a92-4329-8fcc-cec7c25e3b31.jpg?v=1788726705","url":"https:\/\/voomisupply.com\/products\/accupro-312777-corner-radius-end-mill-3-4-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
