Built from micrograin solid carbide, this tool delivers high wear resistance and edge retention across a range of ferrous and non-ferrous materials. It features a 3\/4 inch cutting diameter, a 5 inch length of cut, and an 8 inch overall length, making it well-suited for deep-cavity and extended-reach milling work. The zirconium nitride (ZrN) coating reduces friction and extends tool life. With three flutes and a 37-degree right-hand spiral helix, it provides an efficient balance of chip evacuation and cutting performance. Licensed machinists and CNC operators install and run this tool in production shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical and horizontal CNC machining centers for slotting, profiling, and peripheral milling operations. The centercutting geometry allows for plunge entry directly into the workpiece without a pre-drilled hole. The 3\/4 inch shank diameter provides solid tool holding in standard ER, side-lock, and shrink-fit collet systems. It is appropriate for general-purpose milling of steel, stainless steel, cast iron, and non-ferrous alloys where a long-reach, high-flute-count carbide tool is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eZrN (zirconium nitride) coating reduces heat and tool wear during cutting\u003c\/li\u003e\n  \u003cli\u003e37-degree right-hand spiral helix promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003e3 flutes provide a balance of chip clearance and surface finish capability\u003c\/li\u003e\n  \u003cli\u003eMatched 3\/4 inch cutting diameter and shank diameter for consistent tool holding\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 accepting a 3\/4 inch diameter shank.

Always power down and lock out the spindle before changing tooling. Confirm runout at the cutting diameter with a dial indicator before production use, and verify that the collet or chuck is clean and free of chips or debris prior to tightening. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and cut depth.\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 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5 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: 3\/4 inch (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\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\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\u003eCentercutting\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: 1.5 pounds\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: 315047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727521415474,"sku":"315047","price":697.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28f5a3090ec8c2dc50a024cf51dc2347.jpg?v=1788678847","url":"https:\/\/voomisupply.com\/products\/accupro-315047-square-end-mill-3-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
