Built from micrograin solid carbide, this tool delivers the rigidity and edge retention required for demanding cuts. It features a 0.25-inch diameter with a 1.5-inch length of cut and a 6-inch overall length, placing it in the extra-long category for reach into deep pockets or extended setups. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This is a centercutting tool, meaning it can plunge directly into a workpiece. Machinists, toolroom operators, and CNC programmers select this end mill for applications where standard-length tools cannot reach.\u003c\/p\u003e\u003cp\u003eThis end mill suits vertical and horizontal machining centers, CNC knee mills, and manual knee mills running right-hand spindles. The extra-long overall length makes it appropriate for deep-pocket milling, long-reach profiling, and applications where workholding fixtures or part geometry prevents use of a standard-length tool. The 4-flute spiral configuration supports finishing and light-to-moderate material removal in steel, aluminum, and similar machinable materials. The uncoated finish is suited for general-purpose use or applications where a specific coating is not required by the material or operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch OAL provides reach for deep-pocket and long-reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for use in standard right-hand spindle machines\u003c\/li\u003e\n\u003cli\u003eUncoated finish for general-purpose compatibility across common machinable materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-purpose end mill for use in right-hand spindle machining centers and knee mills accepting a 0.25-inch round shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Confirm the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 0.25-inch shank fully into a properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout at the cutting end before beginning a cut to avoid premature tool wear or dimensional error.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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: 0.12 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12183636\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749903073586,"sku":"12183636","price":66.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7552ee9b379e93f6f1cfad8ae5d27d41.jpg?v=1788911896","url":"https:\/\/voomisupply.com\/products\/accupro-12183636-square-end-mill-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
