It features a 11\/64 inch (0.1719 inch) cutting diameter with a 2-flute spiral flute configuration and a 40-degree helix angle. The AlTiN coating provides heat and wear resistance, making it well-suited for dry or high-speed cutting in ferrous and hardened materials. At 2 inches overall length with a 3\/8 inch length of cut, this is a stub-length tool that prioritizes rigidity over reach. Licensed machinists and CNC operators are the typical end users for this style of end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for slot milling, profile milling, and plunge cutting in tight-tolerance applications. The centercutting geometry allows direct plunge entry without a pre-drilled hole. Right-hand cut and right-hand flute orientation are standard for conventional CNC machining centers. The micrograin carbide substrate supports tighter tolerances and longer tool life compared to standard-grade carbide, particularly in harder workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pilot drilling\u003c\/li\u003e\n\u003cli\u003eStub length (3\/8 inch LOC) maximizes stiffness and minimizes deflection in shallow cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute for use on standard CNC machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill for use in CNC machining centers and manual mills equipped with a 3\/16 inch collet or matching tool holder.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 3\/16 inch shank fully into a clean, properly sized collet or end mill holder and torque the retention hardware per the tool holder manufacturer specifications. Inspect the tool edge condition before each use and replace at the first sign of chipping or excessive wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/64 inch (0.1719 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: 2\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\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\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eLength Type\u003c\/strong\u003e: Stub\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: 12181604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738672070962,"sku":"12181604","price":40.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/210b15f37595d860c12194efb8357fed.jpg?v=1788802620","url":"https:\/\/voomisupply.com\/products\/accupro-12181604-square-end-mill-11-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
