With a 0.1181-inch (3.00 mm) mill diameter and a 0.4724-inch (12.00 mm) length of cut, this two-flute tool is built for tight-tolerance work in small-feature applications. The AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions. A 40-degree helix angle and spiral flute geometry promote efficient chip evacuation. Micrograin carbide construction delivers the hardness and edge retention needed for ferrous and non-ferrous materials at elevated cutting speeds.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC milling operations in job shops, tool rooms, and production machining environments. Its centercutting design allows plunge entry as well as conventional peripheral milling. With a 3.00 mm (0.1181-inch) shank diameter, it mounts directly in standard collet systems sized for 3 mm shanks. Right-hand cut and right-hand flute geometry match standard spindle rotation, making it a straightforward drop-in for most vertical and horizontal machining centers. The regular-length configuration keeps the tool rigid in short-reach applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1181-inch (3.00 mm) mill diameter with mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree spiral helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry supports both plunge and peripheral milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3 mm shank square end mill compatible with collet chucks, ER collet systems, and end mill holders sized for 3 mm shanks on CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine power locked out. Ensure the collet or holder bore matches the 3 mm shank diameter and that the tool is seated to the correct gauge length before tightening. Inspect the cutting edges for chips or wear before each use. Follow the machine manufacturer and tooling manufacturer recommendations for speeds, feeds, and coolant strategy appropriate to this tool diameter and workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\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\u003eLength of Cut\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\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: 38.00 mm\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\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 12181253\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734259401010,"sku":"12181253","price":35.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/072c6169802fde2a7d85216fbec9131f.jpg?v=1788761611","url":"https:\/\/voomisupply.com\/products\/accupro-12181253-square-end-mill-0-1181-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
