Built from micrograin solid carbide, this tool offers the rigidity and edge retention needed for demanding cutting applications. The 0.060 inch corner radius reduces stress concentrations at the cutting edge and produces a blended radius on inside corners. A ZrN (zirconium nitride) coating adds surface hardness and improves lubricity, extending tool life in dry or light-lubrication machining environments. With a 45-degree helix angle and two right-hand spiral flutes, it delivers smooth chip evacuation and reduced cutting forces during full-depth passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual knee mills in job shop, tool-and-die, and general metalworking operations. The 0.750 inch diameter and 1.625 inch length of cut make it appropriate for medium-depth slotting, peripheral milling, and profiling passes where a corner radius is specified on the finished part. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. It is intended for use by machinists and CNC operators working with steel, stainless, aluminum, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.060 inch corner radius for blended inside corner geometry and improved tool life at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides high hardness and wear resistance across a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eZrN coating increases surface lubricity and reduces heat buildup during cutting\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle with two right-hand spiral flutes promotes efficient chip flow and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 3\/4 inch shank diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-geometry replacement or stock cutting tool for CNC machining centers and manual mills accepting a 3\/4 inch straight shank end mill holder or collet.

Secure the shank fully in a precision collet or end mill holder to the depth specified by the toolholder manufacturer, ensuring runout is within acceptable limits before cutting. Confirm spindle speed, feed rate, and depth of cut against published carbide end mill guidelines for the specific workpiece material before engaging the cut. Inspect the cutting edges for chips or coating damage before each use and replace the tool if edge condition is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.000 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eVariable Helix\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 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: 0.05 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: 313447\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733128216882,"sku":"313447","price":314.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14244abe6f05a202ada44b54f1ff3d61.jpg?v=1788751603","url":"https:\/\/voomisupply.com\/products\/accupro-313447-corner-radius-end-mill-3-4-in-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
