It features a 3\/8-inch cutting diameter with a 9\/16-inch length of cut and a 2-inch overall length. The 4-flute, right-hand spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. The nACRo finish enhances wear resistance and thermal stability, extending tool life in demanding cuts. This end mill is centercutting, allowing plunge entry, and is manufactured from micrograin solid carbide for consistent edge integrity and dimensional accuracy.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous metals, alloys, and similar materials in CNC machining centers and manual mills. The 3\/8-inch shank diameter matches standard ER and straight-bore collet systems common in production and job shop environments. With no chipbreaker and no extended reach, it is optimized for standard-depth slotting, profiling, and peripheral milling operations. Machinists and CNC operators in aerospace, general manufacturing, and tool-and-die applications will find this a direct-fit tool for everyday milling work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge retention and dimensional stability\u003c\/li\u003e\n  \u003cli\u003enACRo coating improves wear resistance and heat resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with 4 spiral flutes for efficient chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for compatibility with standard spindle direction\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank solid carbide square end mill with a 3\/8-inch shank diameter, compatible with ER collet chucks, straight-bore tool holders, and similar workholding systems sized for 3\/8-inch shanks.\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 locked out before changing tooling. Seat the shank fully into the collet or tool holder and torque the collet nut to the tool-holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, and confirm spindle direction matches the right-hand cut designation of this tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: nACRo\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\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: 0.25 pounds\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: 12176925\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750404063538,"sku":"12176925","price":68.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/956f5897da136d5317737e59273360e6_4c844a84-77b6-4bf3-9320-6bca76c973bf.jpg?v=1788915299","url":"https:\/\/voomisupply.com\/products\/accupro-12176925-square-end-mill-3-8-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
