With 2 helical flutes and a centercutting geometry, this end mill can plunge directly into workpiece material as well as perform peripheral and slot milling. The mill diameter measures 0.328 inches (21\/64 inch) with a 3\/8-inch cylindrical shank and a 7\/8-inch length of cut. A helix angle in the 38 to 42 degree range promotes efficient chip evacuation and reduces heat buildup at the cutting zone, making it suitable for both roughing and finishing passes in a variety of CNC and manual milling applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers, knee mills, and manual vertical mills where close-tolerance slot milling, profiling, and plunge cutting are required. The 21\/64-inch diameter is a common size for precision feature work in tool-and-die, aerospace component, and general metalworking applications. Solid carbide construction provides greater rigidity and wear resistance compared to high-speed steel, particularly at elevated spindle speeds. The 2.5-inch overall length gives adequate reach for most standard fixturing setups without sacrificing stiffness.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into material without pre-drilling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for extended tool life and higher cutting speeds versus HSS\u003c\/li\u003e\n\u003cli\u003eHelical flute geometry promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003e38 to 42 degree helix angle balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eCylindrical shank compatible with standard ER and end mill holders in 3\/8-inch bore\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker for cleaner finish cuts and consistent chip formation in full-slot applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 3\/8-inch cylindrical shank tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe-lock state before changing tooling. Seat the cylindrical shank fully and evenly in the collet or end mill holder and torque the retention mechanism according to the holder manufacturer specifications. Inspect the cutting edges for chips or damage before each use, as carbide tools are brittle and should not be used if the edge is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.328 inches (21\/64 inch)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 to 42 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 14788335\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744749814066,"sku":"14788335","price":59.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09815ded90c7cba26c4a4827744978eb.jpg?v=1788860217","url":"https:\/\/voomisupply.com\/products\/accupro-14788335-square-end-mill-21-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
