It features a 0.2756 inch mill diameter, a 0.748 inch length of cut, and a 40-degree helix angle that promotes smooth chip evacuation and reduced cutting forces. The TiCN coating improves surface hardness and wear resistance, extending tool life in demanding applications. With two spiral flutes and a centercutting geometry, this end mill handles both peripheral and plunge cutting. It is installed and run by machinists and CNC operators working in job shops, toolrooms, and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and pocketing operations in a variety of workpiece materials. The micrograin carbide substrate provides the rigidity needed for tight-tolerance cuts. The 0.3150 inch shank diameter fits standard collets and toolholders. Its regular-length configuration makes it a practical choice for general-purpose CNC milling work where extended reach is not required. Right-hand cut and right-hand flute orientation are standard for conventional CNC spindle setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2756 inch mill diameter with a mill diameter tolerance of +0.000 \/ -0.002 inches for precise fitment\u003c\/li\u003e\n  \u003cli\u003eTiCN finish for improved wear resistance and surface hardness\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute  -  compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard collet chucks and end mill holders accepting a 0.3150 inch shank diameter in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator. Always confirm spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Inspect the cutting edges for chipping before each use and replace the tool if edge integrity is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2756 inches (7.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.748 inches (19.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63.00 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\u003eFinish\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  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12181357\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740029387058,"sku":"12181357","price":71.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ead574ced71fa55dc7767af7cccc43d1.jpg?v=1788821611","url":"https:\/\/voomisupply.com\/products\/accupro-12181357-square-end-mill-0-2756-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
