With a 5\/32-inch (0.1563-inch) cutting diameter and three spiral flutes ground at a 40-degree helix angle, this tool delivers efficient chip evacuation and a smooth cutting action. The AlTiN coating extends tool life in high-temperature cutting environments, particularly in ferrous and hardened materials. The micrograin carbide substrate provides rigidity and edge retention. It is single-end, centercutting, with right-hand cut and right-hand flute geometry, allowing plunge entry and full-slot milling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual knee mills used in job shops, maintenance departments, and production facilities. The regular-length body and compact 2-inch overall length make it appropriate for close-clearance cuts and work in tighter setups. The 3\/16-inch shank diameter fits standard collets and end mill holders commonly used for small-diameter tooling. It handles slotting, profiling, and side milling in steel, stainless steel, cast iron, and similar materials where AlTiN coating provides a thermal barrier.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention in demanding cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for extended tool life in high-heat ferrous machining\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute geometry for standard CNC and manual mill spindle rotation\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of +0.000 \/ -0.002 inches ensures consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard collet chucks and end mill holders accepting a 3\/16-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and CNC operators. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the collet bore and shank for chips or debris before seating the tool to prevent runout.\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eLength of Cut Range\u003c\/strong\u003e: 0.5000 to 0.6000 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: 12181910\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727295414578,"sku":"12181910","price":35.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8798346eb31ac1c14b4778479aaadaa4.jpg?v=1788675996","url":"https:\/\/voomisupply.com\/products\/accupro-12181910-square-end-mill-5-32-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
