Built from micrograin carbide stock and finished with an AlTiN coating, it handles elevated cutting temperatures and abrasive workpieces that would degrade lesser tooling. The 40-degree spiral helix promotes efficient chip evacuation and smooth cutting action. At 3\/16 inch in diameter with a 3\/4 inch length of cut, this is a small-diameter tool suited for tight-tolerance slot milling, profiling, and contouring where rigidity and finish quality matter. Installation requires a compatible collet or end mill holder sized for the 3\/16 inch shank. Licensed machinists, tool-and-die makers, and precision CNC operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual knee mills running ferrous alloys, stainless, aluminum, and hardened materials where an AlTiN coating provides thermal protection. The long-length designation gives additional reach for deeper pockets and stepped features without requiring a longer-reach holder. The centercutting geometry allows plunge entry as well as conventional peripheral and slot cutting. Right-hand cut and right-hand flute configuration matches standard spindle rotation on most vertical machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN finish provides heat and oxidation resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e3-flute geometry balances chip room with core strength at 3\/16 inch diameter\u003c\/li\u003e\n\u003cli\u003eLong-length classification extends reach for deeper pockets and stepped features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style solid carbide square end mill compatible with 3\/16 inch collets, shrink-fit holders, and end mill holders used on CNC vertical machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists using a properly sized 3\/16 inch collet or end mill holder; confirm runout before cutting. Verify spindle speed and feed rate against manufacturer cutting data for the specific workpiece material and AlTiN-coated carbide tooling. Inspect the cutting edges under magnification before use; do not run chipped or damaged tooling. Power down and lock out the spindle before changing or adjusting tooling.\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\/4 inch (0.7500 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: 2-1\/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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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\u003eLength Type\u003c\/strong\u003e: Long\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: 0.06 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: 12182210\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750350684466,"sku":"12182210","price":34.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c28860af851df73b9fcdae140f72df7b.jpg?v=1788914965","url":"https:\/\/voomisupply.com\/products\/accupro-12182210-square-end-mill-3-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
