Built from micrograin carbide stock, it offers a 1\/4 inch cutting diameter with a 3\/8 inch length of cut and a 2.5 inch overall length. The ZrN (zirconium nitride) coating reduces friction and extends tool life during high-speed cutting operations. A variable helix geometry helps break up harmonic chatter, improving surface finish and cutting stability. This is a single-end, centercutting tool with a right-hand cut and right-hand flute spiral, suited for machinists running milling machines or machining centers in job shops and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill fits stub-length applications where rigidity matters more than reach. The 1\/4 inch shank diameter matches the 1\/4 inch cutting diameter, making it compatible with standard 1\/4 inch collets and end mill holders. Its three-flute design balances chip evacuation with cutting edge strength, making it a practical choice for profiling, slotting, and light pocketing in ferrous and non-ferrous materials where a ZrN-coated micrograin carbide tool is appropriate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 compatible materials\u003c\/li\u003e\n\u003cli\u003eVariable helix design minimizes chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute configuration\u003c\/li\u003e\n\u003cli\u003eStub length for maximum rigidity in short-reach setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for standard 1\/4 inch collet chucks and end mill holders used on vertical and horizontal milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and locked out before loading or changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism to the tool holder specification. Inspect the cutting edges and coating condition before each use and replace tooling that shows visible chipping or wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 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: 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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 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: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 2500229\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735648960818,"sku":"2500229","price":79.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21ba1e4f8d1ef456d33d6dd880eaf032.jpg?v=1788773448","url":"https:\/\/voomisupply.com\/products\/accupro-2500229-square-end-mill-1-4in-3-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
