Built from micrograin solid carbide, it delivers rigidity and wear resistance in demanding cutting environments. The 1\/2 inch diameter cutter features a 45-degree helix angle and a ZrN (zirconium nitride) coating that reduces friction and extends tool life at elevated cutting speeds. With 2 spiral flutes and a centercutting geometry, this end mill handles plunge entry, slotting, profiling, and peripheral milling. It is a right-hand cut, right-hand flute tool suited for CNC machining centers and manual mills where consistent, repeatable results are required.\u003c\/p\u003e\u003cp\u003eThis end mill is a general-purpose choice for shops machining aluminum, steel, stainless steel, and similar materials where a short-LOC, standard-reach tool fits the job. The 1 inch length of cut paired with a 3 inch overall length keeps the tool stiff and minimizes deflection during aggressive passes. The ZrN finish adds a layer of lubricity that benefits dry and semi-dry cutting strategies, helping maintain edge sharpness over longer run times. Machinists, tool-and-die makers, and CNC operators working in job shop and production environments will find this geometry well-suited to everyday roughing and finishing tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces friction and extends tool life in dry or semi-dry cuts\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute configuration for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eConsistent mill diameter tolerance of +0.000 \/ -0.002 inches for repeatable fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 1\/2 inch collet or end mill holder systems on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully within a clean, properly sized collet or end mill holder, verifying runout before cutting. Power down and lock out the spindle before changing tooling. Confirm that feed rates, speeds, and depth of cut are within the machine and tool manufacturer guidelines for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (+0.000 \/ -0.002 inches tolerance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches (+0.0001 \/ -0.0004 inches tolerance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eExtended Reach\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 313300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733050392882,"sku":"313300","price":115.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f2bbac397a715b772591f1915fbad3b.jpg?v=1788750954","url":"https:\/\/voomisupply.com\/products\/accupro-313300-square-end-mill-1-2-in-2-flute-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
