With a 1\/2 inch cutting diameter, a 5\/8 inch length of cut, and a 3 inch overall length, this tool handles slotting, profiling, and peripheral milling with consistent accuracy. The three-flute geometry with a variable helix design reduces chatter and harmonic vibration during cutting, improving surface finish and tool life. A ZrN (zirconium nitride) coating adds hardness and heat resistance to the micrograin carbide substrate, making this end mill well suited for a range of ferrous and non-ferrous workpiece materials. It is single-end, right-hand cutting, and right-hand flute direction.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for precision part manufacturing, mold work, die work, and general-purpose metal removal. The stub length type and 1\/2 inch shank diameter make it compatible with standard ER and side-lock toolholders. Its centercutting capability allows plunge entry into the workpiece, expanding its use to pocketing and ramping operations. Machinists, tool and die makers, and CNC operators in job shops and production facilities are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch cutting diameter with a plus 0.000 \/ minus 0.002 inch diameter tolerance for precise fitment\u003c\/li\u003e\n  \u003cli\u003eVariable helix flute geometry reduces chatter and improves surface finish in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eZrN coating increases surface hardness and thermal resistance, extending tool life\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction delivers rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry for pocketing and ramping operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute spiral for use with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for CNC machining centers and manual mills using 1\/2 inch shank toolholders with right-hand spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholder torque and runout procedures for the machine in use. Ensure the spindle is fully stopped and locked out before changing tooling. Verify shank engagement depth meets the toolholder manufacturer minimum before tightening. Inspect the collet or holder for wear or contamination that could affect runout and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.625 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\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: 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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 2500159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747616686386,"sku":"2500159","price":143.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fda248eebc8936b9fd52095af817767f.jpg?v=1788883534","url":"https:\/\/voomisupply.com\/products\/accupro-2500159-square-end-mill-1-2-in-3-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
