Built from micrograin carbide stock, it delivers the rigidity and edge retention needed for ferrous and non-ferrous materials. The nACRo coating reduces friction and heat buildup at the cutting edge, extending tool life in demanding cutting conditions. With a 40-degree helix angle and spiral flute geometry, this end mill promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows plunge entry directly into the workpiece. This tool is sold as a single unit and is intended for use by machinists and CNC operators running milling machines, machining centers, or manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose and finish milling in production and job shop environments. The 1\/4 inch diameter and 1-1\/2 inch length of cut make it well suited for slotting, profiling, and contouring in tight-tolerance work. The 6 inch overall length provides extended reach for deep-cavity or long-reach milling scenarios where a standard-length tool would not access the feature. Right-hand cut and right-hand flute orientation follow standard milling machine spindle direction for direct compatibility with conventional CNC and manual setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003enACRo finish coating for reduced friction and improved tool life\u003c\/li\u003e\n  \u003cli\u003e40-degree spiral helix promotes aggressive chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length provides extended reach into deep cavities\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 1\/4 inch collets, ER collet chucks, end mill holders, and other standard 1\/4 inch shank toolholding systems on CNC machining centers and manual milling machines.\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 machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Torque collet nuts or set screws according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the first cut, as excessive runout will accelerate edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\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\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\u003eFinish\/Coating\u003c\/strong\u003e: nACRo\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\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12178858\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729197334834,"sku":"12178858","price":105.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da9e95d124a763e741fbbee05ddf948f.jpg?v=1788701809","url":"https:\/\/voomisupply.com\/products\/accupro-12178858-square-end-mill-1-4-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
