With a 15\/64 inch (0.2344 inch) cutting diameter and a 3\/8 inch length of cut, this single-end tool delivers clean, square-shoulder cuts in tight tolerances. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. An nACRo coating improves heat resistance and extends tool life in abrasive or high-speed applications. Machinists and toolroom technicians working with CNC mills or manual vertical mills select this end mill for detail work, slotting, and profiling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for small-diameter milling work in production and job-shop environments. Its 1\/4 inch shank diameter fits standard collets and end mill holders found on most CNC machining centers and manual knee mills. The 2 inch overall length keeps the tool compact and rigid, minimizing deflection during cuts. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling setups. The micrograin carbide substrate supports cutting in steel, stainless, cast iron, aluminum, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/64 inch (0.2344 inch) cutting diameter with a tight tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003enACRo coating for extended tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flutes for standard milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch collets and end mill holders on CNC machining centers and manual milling machines.

Inspect the collet or end mill holder for wear or contamination before seating the tool. Torque the collet nut to the machine manufacturer specification using the appropriate spanner wrench. Verify runout with a dial indicator before beginning a cut, particularly in tight-tolerance applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 15\/64 inch (0.2344 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.25 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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nACRo\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\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: 12178786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730590499122,"sku":"12178786","price":47.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfba2612abe6e7053c2c5a3fe9ab0d5f.jpg?v=1788720046","url":"https:\/\/voomisupply.com\/products\/accupro-12178786-square-end-mill-15-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
