It features a 7\/16-inch cutting diameter, a 1-1\/2-inch length of cut, and a 6-inch overall length, placing it in the extra-long category for applications requiring extended reach. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating adds surface hardness and lubricity, extending tool life in abrasive or high-temperature cutting conditions. Micrograin carbide construction provides the rigidity and edge retention needed for finish and semi-finish milling passes.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, profiling, and peripheral milling operations on CNC machining centers and manual knee mills. The extra-long overall length makes it appropriate for deep-pocket work or setups where standard-length tools cannot reach the workpiece. It is used by machinists in job shops, production facilities, and tool-and-die operations. Right-hand cut and right-hand spiral flute geometry are standard for conventional CNC spindle rotation. The centercutting design allows plunge entry directly into the material without a pre-drilled hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiCN coating for increased surface hardness and reduced tool wear\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch OAL for deep-pocket and extended-reach setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tool for any spindle or collet system accepting a 7\/16-inch shank diameter, including ER, TG, and straight-bore collet chucks standard on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove end mills only with the spindle fully stopped and machine power off or in E-stop. Use a properly sized collet or tool holder matching the 7\/16-inch shank diameter and torque the drawbar or collet nut to the tool-holder manufacturer's specification. Inspect the shank and collet bore for chips or debris before seating the tool. Follow shop safety protocols and applicable OSHA machine-guarding requirements during tool changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\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\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 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\u003eCoating\u003c\/strong\u003e: TiCN\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\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\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: 0.3 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: 12183715\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749134696754,"sku":"12183715","price":133.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc64439b36b286b5bf4cecf493b1741b.jpg?v=1788902452","url":"https:\/\/voomisupply.com\/products\/accupro-12183715-square-end-mill-7-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
