With a 0.1181 inch (3.00 mm) mill diameter and a 0.4724 inch (12.00 mm) length of cut, this end mill handles slotting, profiling, and contouring in tight-tolerance applications. The 2-flute geometry paired with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN (titanium carbonitride) coating adds surface hardness and lubricity, extending tool life in abrasive cutting conditions. Machinist-grade micrograin carbide substrate ensures edge integrity at elevated cutting speeds.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard CNC machining centers, manual mills, and high-speed spindle applications requiring a 3.00 mm shank diameter. The right-hand cut, right-hand spiral flute configuration is the industry-standard orientation for conventional and climb milling on vertical and horizontal setups. The centercutting design allows plunge entry, making it suitable for ramping and pocket milling operations. Regular-length construction keeps it versatile for general shop use without sacrificing rigidity at small diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide substrate for high edge strength and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge in abrasive materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge and ramp entry into workpiece\u003c\/li\u003e\n\u003cli\u003e2-flute design maximizes chip clearance in slotting and deep-pocket operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC and manual mill compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose square end mill for CNC machining centers and manual vertical mills accepting a 3.00 mm shank diameter collet or toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and machine power locked out per shop safety protocols. Seat the shank fully into a matched collet or end mill holder and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning cuts, as excessive runout at this diameter accelerates edge wear and can cause tool breakage. At 0.1181 inch diameter, select conservative feed and speed parameters and avoid excessive side load or interrupted cuts without proper support.\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\u003eLength of Cut\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 38.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 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: TiCN\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\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\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: 12181252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741273915698,"sku":"12181252","price":33.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6a2885f415d01c67529c86799fa02b7.jpg?v=1788830462","url":"https:\/\/voomisupply.com\/products\/accupro-12181252-square-end-mill-0-1181-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
