Built from micrograin carbide and coated with AlCrTiN, this tool handles demanding ferrous and non-ferrous applications where heat and wear resistance are critical. The 1\/4 inch diameter, 4-flute configuration with a variable helix and variable index geometry reduces chatter and improves surface finish across a range of cutting conditions. At 2 inches overall length with a 5\/16 inch length of cut, this is a short-series end mill suited for close-tolerance work. It is installed and used by machinists and CNC operators in job shops, production floors, and toolrooms.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC mills, and manual milling machines where a 1\/4 inch straight-cylindrical shank is compatible with the spindle or collet system. The short overall length and tight TIR maximum of 0.0005 inches make it well suited for finishing passes and applications requiring dimensional accuracy. The right-hand cut and right-hand helical flutes are standard for conventional milling setups. The AlCrTiN coating extends tool life in harder materials including alloy steels and stainless. This is a single-end, centercutting tool, meaning it can plunge as well as profile cut.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating for heat and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces vibration and chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eh6 shank diameter tolerance for precise collet fit and minimal runout\u003c\/li\u003e\n\u003cli\u003eTIR maximum of 0.0005 inches for tight dimensional control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for machining setups requiring a 1\/4 inch straight-cylindrical shank end mill with a short length of cut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by machinists or CNC operators using a compatible collet, end mill holder, or tool chuck rated for a 1\/4 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet condition and cleanliness before seating the shank to avoid runout issues. Follow the machine tool manufacturer guidelines for torque and clamping when securing the tool holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches \/ 6.35 mm)\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\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inch (0.3125 inches \/ 7.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches (50.8 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.040 \/ -0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches (0.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eCentercutting\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: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 95169069\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754392682802,"sku":"95169069","price":72.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ad4b0d236f0b4317da444a44746b87e.jpg?v=1788944999","url":"https:\/\/voomisupply.com\/products\/accupro-95169069-square-end-mill-1-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
