It carries a 3\/16-inch cutting diameter and a 3\/8-inch length of cut, making it well suited for slotting, profiling, and light pocketing operations in confined spaces. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces across a range of workpiece materials. With an overall length of 2 inches and a matching 3\/16-inch shank diameter, the tool fits standard collet and end mill holders without adapters. The bright, uncoated finish leaves the carbide substrate exposed for applications where coating buildup or heat sensitivity is a concern.\u003c\/p\u003e\u003cp\u003eThis stub-length end mill is used in CNC machining centers, manual knee mills, and benchtop CNC routers where short reach and rigidity are priorities. Its double-end configuration doubles usable tool life before the cutter is retired, offering a practical cost advantage in high-volume shops. Right-hand cutting and right-hand flute direction are standard for conventional spindle-up milling setups. The centercutting geometry allows the tool to plunge directly into material, supporting ramping and helical interpolation entry strategies without a pre-drilled pilot hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces chatter\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, extending service life before replacement\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry supports direct plunge, ramp, and helical entry cuts\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for materials sensitive to coated-tool heat transfer\u003c\/li\u003e\n\u003cli\u003eStub length type delivers maximum rigidity for shallow-depth milling passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for standard 3\/16-inch collet chucks, ER collet systems, and end mill holders used in CNC and manual milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank in a properly sized collet or end mill holder to the full recommended grip length before operation. Confirm spindle runout is within acceptable limits prior to cutting, as excessive runout accelerates carbide edge wear and can cause tool breakage. Always verify feed rate, depth of cut, and spindle speed are appropriate for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\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\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: 12185197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730623070514,"sku":"12185197","price":41.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b39686c3bb505e6e460a5510e59cb69.jpg?v=1788720423","url":"https:\/\/voomisupply.com\/products\/accupro-12185197-square-end-mill-3-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
