The tool measures 0.3906 inches (25\/64 inch) in cutting diameter with a 1-inch length of cut and a 7\/16-inch shank diameter. A 40-degree helix angle combined with a spiral flute geometry promotes efficient chip evacuation and reduces cutting forces. The AlTiN coating provides thermal resistance, extending tool life in high-speed dry or semi-dry cutting applications. At 2-3\/4 inches overall length, this is a standard-length, single-end configuration suited for general-purpose slot milling, profiling, and peripheral cutting operations.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual knee mills for slotting, contouring, and profile milling. The centercutting design allows plunge entry into the workpiece without pre-drilling. Right-hand cut and right-hand flute geometry are standard for conventional spindle rotation. The micrograin carbide substrate supports high surface footage and is well-suited for shops running aluminum, steel, stainless, and similar materials at elevated speeds. It is a regular-length tool appropriate for general shop floor use where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for high-temperature resistance in dry and high-speed cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduced cutting pressure\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry into material\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute — compatible with standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a drop-in replacement end mill for standard 7\/16-inch collet or end mill holder setups on CNC machining centers and conventional vertical mills requiring a 25\/64-inch diameter, 2-flute square end mill with a 1-inch length of cut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into a clean, undamaged collet or end mill holder and torque the retention hardware to the machine tool manufacturer's specification. Inspect the collet and holder for runout before initiating a cut, as excessive runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inches)\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\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\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\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: 12181436\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733291237682,"sku":"12181436","price":77.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b341e58472a6cbaaee079066f7b7d276_9b8927af-c9a9-4493-b0be-49227bc11a33.jpg?v=1788753646","url":"https:\/\/voomisupply.com\/products\/accupro-12181436-square-end-mill-25-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
