It features a 0.5 inch cutting diameter, a 1.25 inch length of cut, and a 6 inch overall length, making it well suited for deep-reach applications where rigidity and accuracy matter. The micrograin carbide substrate provides hardness and wear resistance, while the ZrN (zirconium nitride) coating reduces friction and extends tool life in ferrous and non-ferrous materials. This tool is installed and used by machinists and CNC operators in production and job shop settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for slotting, profiling, and peripheral milling in a range of materials including steel, aluminum, and engineered alloys. The centercutting geometry allows for plunge entry, adding flexibility to the operation. The 37-degree helix angle promotes smooth chip evacuation and reduced cutting forces. With a 0.5 inch shank diameter, it mounts directly to standard collets, end mill holders, and shrink-fit tooling commonly found in vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and extends tool life in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003e37-degree spiral flute helix promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC spindle use\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of plus 0.000 \/ minus 0.002 inches for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 0.5 inch shank square end mill applications in vertical and horizontal CNC machining centers using collet chucks, end mill holders, or shrink-fit toolholders rated for 0.5 inch shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in a safe, locked-out state before tool changes. Ensure the shank is clean and free of chips before seating in the holder, and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator after clamping before resuming cuts. Consult applicable shop safety standards and machine tool manufacturer guidelines for proper tool-change procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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 \/ Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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: plus 0.000 \/ minus 0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 \/ minus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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: 319901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746202976562,"sku":"319901","price":259.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7a13a0cc9cdb9c97b6eb0551905b927.jpg?v=1788867081","url":"https:\/\/voomisupply.com\/products\/accupro-319901-square-end-mill-0-5-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
