It features a 1\/2-inch mill diameter with a 2.5-inch length of cut and a 5-inch overall length. The APLUS coating improves wear resistance and surface finish during extended cutting operations. A variable index flute geometry reduces harmonic vibration, enabling higher feed rates and better tool life in demanding production environments. This end mill is installed and operated by machinists, tool-and-die makers, and CNC programmers working with vertical or horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose and high-efficiency milling applications including slotting, profiling, and pocketing in steel, stainless steel, cast iron, and similar materials. Its 5-flute configuration supports higher chip loads per revolution compared to 4-flute designs, making it well-suited for semi-finish and finish passes on production runs. The straight cylindrical shank fits standard ER collet chucks and end mill holders accepting a 1\/2-inch bore. Right-hand cut and right-hand helix flute direction is standard. The centercutting geometry allows plunge entry where required by the operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-flute helical design increases material removal rate versus 4-flute alternatives\u003c\/li\u003e\n  \u003cli\u003eAPLUS coating provides enhanced wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eVariable index spacing reduces chatter and harmonic vibration during cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits plunge milling entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with right-hand helix flute direction\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard 1\/2-inch bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard ER collet chucks, shrink-fit holders, and set-screw end mill holders with a 1\/2-inch bore, as used on vertical and horizontal CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and locked out before seating or removing the tool from the holder. Verify runout with a dial indicator after clamping to confirm concentricity within the machine and holder specifications. Follow the tool manufacturer and machine builder guidelines for feed rate, spindle speed, and depth-of-cut parameters appropriate to the workpiece material.\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 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: APLUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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 Index\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\u003eWeight\u003c\/strong\u003e: 0.421 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 81715\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51730904875314,"sku":"81715","price":205.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c05a2165a410de664ba7f68e184443a_f58ecddd-8fd7-4ed8-8ff6-5db8a4bf8c59.jpg?v=1788724570","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81715-square-end-mill-1-2-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
