It has a 5\/32 inch (0.1563 inch) cutting diameter, a 1\/2 inch length of cut, and a 3\/16 inch shank diameter, with a 2 inch overall length. The four-flute, right-hand spiral configuration paired with a 40-degree helix angle promotes efficient chip evacuation and a stable cut. Micrograin carbide construction provides the hardness and edge retention needed for demanding milling environments. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose slot milling, peripheral milling, and profiling on CNC machining centers and manual knee mills. The centercutting geometry allows plunge entry directly into the workpiece. The bright uncoated finish makes it well suited for aluminum, brass, and other non-ferrous materials where coatings may cause adhesion issues, though it also performs in mild steels and tool steels when speeds and feeds are selected appropriately. The compact diameter makes it a practical choice for tight-tolerance features and narrow slots.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry with 40-degree helix angle for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill spindles\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suited for non-ferrous and general-purpose applications\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.001\/-0.000 inch for consistent, repeatable results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard square end mill for use in CNC machining centers and manual milling machines that accept a 3\/16 inch straight shank, compatible with ER collets, end mill holders, and other standard toolholding systems sized for that shank diameter.\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 the power is locked out before changing tooling. Seat the shank fully and evenly in the collet or tool holder to the minimum recommended engagement depth before tightening to prevent runout. Verify speeds, feeds, and depth of cut against the material being machined before beginning operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.001\/-0.000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 12177072\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744034128178,"sku":"12177072","price":40.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90b1f17ba8bbd3dbe0f2bf0c7cc2c4a8.jpg?v=1788853285","url":"https:\/\/voomisupply.com\/products\/accupro-12177072-square-end-mill-5-32-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
