It features a 0.4331-inch (11.00 mm) mill diameter and a 0.9843-inch (25.00 mm) length of cut, with four spiral flutes ground to a 40-degree helix angle. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. Micrograin carbide construction delivers edge retention and dimensional stability under demanding cutting conditions. This tool is centercutting, allowing plunge entry directly into the workpiece. Right-hand cut and right-hand flute orientation are standard.\u003c\/p\u003e\u003cp\u003eThe 12182572 is suited for finish and semi-finish milling passes in steel, stainless, cast iron, and similar workpiece materials. The 40-degree helix and AlTiN finish make it a practical choice for higher-speed programs in CNC machining centers and manual knee mills. It fits applications where a regular-length, single-end square profile is needed for shoulder milling, slotting, and peripheral cuts. Overall length is 76.00 mm (approximately 2.992 inches) with a 12.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for heat resistance and extended tool life at elevated surface speeds\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes deliver a balance of chip clearance and surface finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard orientation for conventional CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end square end mill with a 12.00 mm shank diameter, compatible with ER collet chucks, end mill holders, and shrink-fit toolholders sized for 12 mm shanks in CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing cutting tools. Verify collet or toolholder runout before beginning a cut, as excessive runout accelerates edge wear on carbide tooling. Consult the machine tool and toolholder manufacturer guidelines for proper clamping torque and projection length.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4331 inches (11.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 76.00 mm (approximately 2.992 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm\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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12182572\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732581646642,"sku":"12182572","price":118.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/899ba869bede62e2fdd0b87360b82e71.jpg?v=1788744648","url":"https:\/\/voomisupply.com\/products\/accupro-12182572-square-end-mill-0-4331-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
