Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cuts. The tool features a variable helix geometry and a zirconium nitride (ZrN) coating that reduces heat buildup and extends tool life in production environments. With a 3\/4-inch mill diameter, a 1-inch length of cut, and a 4-inch overall length, it is sized for stub-length applications where rigidity is the priority. Licensed machinists and CNC operators working on mills and machining centers are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, profiling, and peripheral milling operations. The stub-length configuration reduces deflection, making it a practical choice for rigid setups where depth of cut is limited to 1 inch. The 3\/4-inch shank diameter matches the mill diameter for direct collet or end mill holder mounting. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling spindles. The center-cutting design allows for plunge entry, adding flexibility in toolpath programming.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN (zirconium nitride) coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003eVariable helix flute geometry reduces harmonic vibration during cutting\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports plunge milling operations\u003c\/li\u003e\n\u003cli\u003eStub-length design (1-inch LOC) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral — compatible with standard CNC milling spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling for standard 3\/4-inch collet chucks, shrink-fit holders, and end mill holders on CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing the tool. Seat the shank fully in the holder to the recommended grip length and verify runout with a dial indicator before production cutting. Follow the machine tool manufacturer's torque specifications for the specific holder type in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.75 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\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\u003eHelix\u003c\/strong\u003e: Variable\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\u003eCenter Cutting\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: 1 pound\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: 2500219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731292193074,"sku":"2500219","price":257.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a74f0f15f864fe7b40befb9d576c2f73.jpg?v=1788729341","url":"https:\/\/voomisupply.com\/products\/accupro-2500219-square-end-mill-3-4-in-3-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
