It features a 3\/4-inch diameter, a 1-5\/8-inch length of cut (1.6250 inches), and a 6-inch overall length with a 37-degree helix angle. The ZrN (zirconium nitride) coating improves wear resistance and extends tool life in ferrous and non-ferrous materials. With an extended reach design and a 3-3\/8-inch reach length, this end mill is well suited for deep-pocket and profiling operations where standard-length tools cannot access the workpart. It is installed by CNC machinists and tool-and-die professionals in production and job shop settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for precision milling operations requiring a controlled corner radius of 0.0300 inches. The three-flute, right-hand cutting and right-hand flute spiral geometry provides a balance between chip evacuation and surface finish quality. The centercutting capability allows direct plunge entry into workpiece material without a pre-drilled pilot hole. It is commonly used in mold-making, die work, and aerospace component machining where tight tolerances and surface integrity are critical. The micrograin solid carbide substrate supports the tight diameter and shank tolerances required for close-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and dimensional stability under cutting loads\u003c\/li\u003e\n  \u003cli\u003eZrN coating for improved hardness and extended tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e37-degree helix angle optimized for chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 3-3\/8 inches (3.3750 inches) for deep-pocket and hard-to-reach profiling\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0300 inches reduces stress concentration and chipping at workpart corners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4-inch diameter CNC milling chucks, collets, and shrink-fit toolholders. Suited for vertical and horizontal machining centers running right-hand spindle rotation.

Secure the 3\/4-inch shank in a precision-balanced toolholder and verify runout before operation, as shank diameter tolerance is -0.0001 to -0.0004 inches. Do not exceed the tool manufacturer's recommended feeds and speeds for the workpiece material and coating type. Inspect the corner radius and cutting edges for chipping or wear before each setup.\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.7125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3-3\/8 inches (3.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00200 to -0.00200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.003000 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\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\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\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 315679\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750713917746,"sku":"315679","price":456.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0bcbaa8c7e20ee993c63e70c73842b4_8e2694fd-02b3-4d2f-a132-72116b0af3cb.jpg?v=1788918897","url":"https:\/\/voomisupply.com\/products\/accupro-315679-corner-radius-end-mill-3-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
