Built from micrograin carbide, it offers a 3\/16 inch cutting diameter with a 3\/8 inch length of cut and a 2 inch overall length. The 3-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes at higher feed rates. Centercutting capability allows direct plunge entry into workpiece material without a pre-drilled starting hole. This is a stub-length tool, providing added rigidity in tight setups. It ships uncoated and is intended for use by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and light contouring operations on ferrous and non-ferrous materials in CNC machining centers and manual mills. The 3\/16 inch shank diameter matches the cutting diameter, making it compatible with standard collet systems of that size. The stub-length configuration reduces deflection in short-reach applications, which is especially useful when working in confined pockets or thin-wall part features. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling on most CNC platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry with 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eStub-length build increases rigidity and reduces tool deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluid on a wide range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 3\/16 inch collet holders and end mill adapters on CNC machining centers, vertical mills, and similar machine tool platforms requiring a stub-length square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Seat the shank fully within the collet or end mill holder to the recommended engagement depth to minimize runout and prevent pull-out under load. Verify tool runout with a dial indicator before beginning a production cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 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)\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eCoating\u003c\/strong\u003e: 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\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: 12182163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730266489138,"sku":"12182163","price":25.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5112b4f66bffaaeb5b91d05fdcd43c1c.jpg?v=1788714293","url":"https:\/\/voomisupply.com\/products\/accupro-12182163-square-end-mill-3-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
