With a 7\/16 inch (0.4375 inch) cutting diameter and a 1-1\/2 inch length of cut, this tool delivers clean, flat-bottomed profiles in slots, pockets, and peripheral cuts. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 6 inches overall length, this is an extra-long configuration suited for deep-reach applications where standard-length end mills cannot access the workzone. Machining centers, manual mills, and CNC equipment all accept this tool through its 7\/16 inch straight shank. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill fits production and job-shop environments requiring extended reach on deep features, tall workpieces, or fixturing setups that push the cutter away from the spindle nose. The centercutting geometry allows plunge entry directly into a workpiece without a pre-drilled pilot hole. Right-hand cut and right-hand spiral flute configuration is the standard for conventional CNC milling spindles. The uncoated micrograin carbide substrate is appropriate for general-purpose machining and re-sharpening applications where a coated surface is not required or desired.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16 inch (0.4375 inch) cutting diameter with a mill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit in close-tolerance work\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration with a 40-degree helix angle for efficient chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eExtra-long 6 inch overall length provides deep-reach capability beyond standard end mill configurations\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction offers rigidity and wear resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eUncoated finish simplifies re-sharpening and suits applications where coating adhesion to the workpiece is a concern\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in milling machines and machining centers accepting a 7\/16 inch straight shank.

Verify that the holder and spindle taper are clean and free of chips before seating the tool. Confirm runout with a dial indicator before beginning production cuts, as excessive runout accelerates flute wear and degrades surface finish. Follow all shop safety protocols and machine-guarding requirements when operating rotating cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 7\/16 inch (0.4375 inch)\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 12183714\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727152513330,"sku":"12183714","price":113.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f45eaf7334c63fe56ba56e944ba324c6.jpg?v=1788674067","url":"https:\/\/voomisupply.com\/products\/accupro-12183714-square-end-mill-7-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
