With a 0.25-inch mill diameter and a 0.375-inch length of cut, this tool delivers the rigidity and edge strength that production machinists and tool-and-die shops demand. The APLUS coating reduces friction and extends tool life in abrasive cutting environments. The variable index flute spacing minimizes chatter and improves surface finish at aggressive feed rates, making it well suited for finishing and semi-finishing passes in steel.\u003c\/p\u003e\u003cp\u003eThis end mill is built for CNC milling centers handling steel components in job shop, production, and precision machining environments. The right-hand cutting and right-hand helical flute direction are standard for conventional CNC spindle rotation. The straight-cylindrical shank fits ER collets, shrink-fit holders, and set-screw side-lock holders with a 0.25-inch bore. It is not centercutting, so it is not intended for direct plunge entry without a pilot hole or ramp-in toolpath.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute geometry increases chip load capacity and improves surface finish in steel\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter during cut\u003c\/li\u003e\n\u003cli\u003eAPLUS coating provides wear resistance and low friction in ferrous materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and edge retention over high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix suit standard CNC mill spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank is compatible with common collet and shrink-fit toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or upgrade tool for CNC machining centers and knee mills using 0.25-inch bore toolholders.

Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder manufacturer specification. Because this tool is not centercutting, program a ramped or helical entry toolpath rather than a direct Z-plunge. Verify runout at the cutting edge after installation to protect both the tool and the workpiece surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\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\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.046 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 26107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51748246585650,"sku":"26107","price":54.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/518d63794db4fa111dcff4cf2a409feb_bef7f31d-8bdb-4852-91b1-6eb502fd2f29.jpg?v=1788891048","url":"https:\/\/voomisupply.com\/products\/helical-solutions-26107-square-end-mill-1-4-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
