It features a 5\/32 inch (0.1563 inch) cutting diameter, a 1\/2 inch length of cut, and a 3\/16 inch shank diameter, with an overall length of 2 inches. The three-flute spiral geometry runs a 40-degree helix angle, promoting efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers edge hardness and wear resistance suited to demanding production environments. This is a right-hand cut, right-hand flute tool with centercutting capability, making it suitable for both plunge entry and standard peripheral milling.\u003c\/p\u003e\u003cp\u003eThe 12181908 is intended for use in CNC machining centers, manual knee mills, and toolroom applications where tight tolerances on small-diameter features are required. Its regular-length profile and uncoated finish make it a practical general-purpose choice for operators working aluminum, mild steel, brass, and similar materials. The centercutting design allows direct plunge interpolation without a pre-drilled pilot hole, adding versatility in slotting and pocketing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention and dimensional stability\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral design with 40-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration — standard CNC and manual mill compatible\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids on a wide range of materials\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit in close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose square end mill for use in standard 3\/16 inch collets or end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Confirm the spindle is fully stopped and locked out before changing tooling. Seat the 3\/16 inch shank fully into a matched collet or end mill holder and torque the retention hardware per the toolholder specification. Verify runout with a dial indicator before beginning the cut, particularly when working to tight diameter tolerances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\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: 3\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 12181908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734234759474,"sku":"12181908","price":30.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b253b8f44baefefdaa158f24b087403.jpg?v=1788761463","url":"https:\/\/voomisupply.com\/products\/accupro-12181908-square-end-mill-5-32-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
