Built from powdered metal, it offers improved toughness and wear resistance compared to standard high-speed steel. The 7\/16-inch cutting diameter pairs with a 3\/8-inch shank, making it compatible with standard collets and end mill holders. With a 1-inch length of cut and a 2-11\/16-inch overall length, it handles typical peripheral and slot milling tasks in production and maintenance machining environments. The 30-degree helix angle promotes smooth chip evacuation and balanced cutting forces during operation.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in vertical machining centers, knee mills, and manual milling machines across job shop and industrial maintenance settings. The centercutting geometry allows it to plunge directly into the workpiece, expanding its use to pocketing and ramp-entry operations. It is sold individually and is appropriate for machinists, toolmakers, and maintenance technicians working with common steel alloys, cast iron, aluminum, and similar materials at moderate cutting speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-inch cutting diameter with a 1-inch length of cut for versatile depth options\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction for improved toughness and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration supports efficient chip removal and surface finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces and reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry and pocketing operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute geometry for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose square end mill compatible with standard 3\/8-inch collets, end mill holders, and milling machine spindles used in job shop and industrial machining applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and at rest before inserting or removing the end mill from the holder. Confirm the shank is fully seated and the collet or set-screw holder is properly torqued per the toolholder manufacturer specifications. Inspect the cutting edges for chips or wear before each use to maintain dimensional accuracy and operator safety.\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 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: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-11\/16 inches\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: 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\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.003 \/ -0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 39460\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747666264370,"sku":"39460","price":49.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f15de44d1ea8d75690a3324491790333.jpg?v=1788884265","url":"https:\/\/voomisupply.com\/products\/accupro-39460-square-end-mill-7-16-inch-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
