It features a 7\/16 inch (0.4375 inch) mill diameter, a 1 inch length of cut, and a 6 inch overall length, placing it in the long-reach category. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Constructed from micrograin solid carbide with a bright, uncoated finish, this tool delivers rigidity and edge retention suited for dry cutting or use with cutting fluids on ferrous and non-ferrous materials. Licensed machinists and CNC operators in job shops and production environments are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, peripheral milling, and plunge cutting in a wide range of materials. The 4-1\/2 inch reach length makes it appropriate for deep-cavity milling, workpiece features with extended reach requirements, and applications where standard-length tools cannot access the cut zone. The centercutting geometry allows direct plunge entry without pre-drilling. Right-hand cut and right-hand flute orientation are standard for conventional CNC mill setups. The spiral flute design with no chipbreaker keeps the tool profile clean for finish-quality passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity at extended reach\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e4 flutes with spiral geometry for smooth surface finish on finish and semi-finish passes\u003c\/li\u003e\n  \u003cli\u003eLong-length category with 4-1\/2 inch reach for deep-cavity and extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with cutting fluids and dry machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for standard 7\/16 inch collet or end mill holder setups on CNC machining centers and manual mills requiring a long-reach, 4-flute square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank in a properly sized collet, end mill holder, or Weldon-style holder, ensuring the full shank engagement depth recommended by the tooling system manufacturer. Verify spindle runout is within acceptable limits before beginning a cut, as excessive runout accelerates edge wear on carbide tooling. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.0000 - 1.2500 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\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 4-1\/2 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 Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\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: Yes\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: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12177146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728827613490,"sku":"12177146","price":167.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08d6881174deb30af9288097753717d5.jpg?v=1788696490","url":"https:\/\/voomisupply.com\/products\/accupro-12177146-square-end-mill-7-16-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
