It features a 3\/4-inch diameter, a 1-inch length of cut, and a 5-inch overall length with an extended reach of 2.5 inches. The ZrN (zirconium nitride) coating improves wear resistance and reduces heat buildup at the cutting edge. With three right-hand spiral flutes and a 37-degree helix angle, the 315656 is centercutting and suited for both roughing and finishing passes where edge integrity and tool life are critical. Machinists and CNC operators working in aerospace, die-mold, or precision job shop environments will find this tool appropriate for deep-cavity and extended-reach applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers for milling steel, stainless steel, and other ferrous and non-ferrous materials where a small corner radius is required to reduce stress concentrations in part features. The 0.060-inch corner radius and micrograin carbide substrate make it well suited for finishing floors and walls in pockets, slots, and contours. The extended reach neck diameter of 0.7125 inches and 2.5-inch reach length allow access to deeper part features without sacrificing rigidity in typical setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch mill diameter with tight tolerance: +0.000000 \/ -0.003000 inches\u003c\/li\u003e\n  \u003cli\u003eZrN coating for improved wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for edge stability and hardness\u003c\/li\u003e\n  \u003cli\u003e0.060-inch corner radius reduces stress risers in milled features\u003c\/li\u003e\n  \u003cli\u003eExtended reach design: 2.5-inch reach length, 0.7125-inch neck diameter\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eThree right-hand spiral flutes with right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a single-end corner radius end mill with a 3\/4-inch shank diameter, compatible with standard CNC milling tool holders accepting 3\/4-inch straight shanks. Shank diameter tolerance is -0.0001 to -0.0004 inches for secure clamping in collet chucks, end mill holders, and hydraulic holders of the appropriate bore size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician with the machine in a fully stopped and locked-out state before tool changes. Ensure the tool holder bore and shank are clean and free of chips or contamination before clamping. Confirm runout with a dial indicator after seating to avoid premature edge wear. Extended-reach tools are more sensitive to overhang and should be set to the minimum projection required for the specific application.\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 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (5.0000 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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 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\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\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: 315656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727981969714,"sku":"315656","price":386.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5678dff7da38308c86c6ca7c57d9d29b.jpg?v=1788685412","url":"https:\/\/voomisupply.com\/products\/accupro-315656-corner-radius-end-mill-3-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
