It features a micrograin carbide substrate and an nACRo coating, which provides high hardness and heat resistance suited for dry or near-dry cutting conditions. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.0781 inches in diameter with a 0.25-inch length of cut, this tool is built for fine-detail work in tight pockets and small-profile slots. It is installed and operated by machinists and tooling technicians on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for small-scale slotting, profiling, and pocketing operations where a fine cutting diameter is required. The centercutting geometry allows for plunge entry without pre-drilling. Right-hand cut and right-hand flute configuration is standard for conventional spindle rotation. The 1\/8-inch shank diameter fits common collet systems used in high-speed spindles and standard milling setups. The 1.5-inch overall length keeps the tool compact to minimize deflection at small diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003enACRo coating for elevated heat resistance and extended tool life in demanding cuts\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute for standard CNC spindle use\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of +0.000 \/ -0.002 inches for precise fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tooling solution for 1\/8-inch collet systems on CNC machining centers and manual milling machines requiring a 5\/64-inch cutting diameter end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a properly sized collet or end mill holder and torque to the machine manufacturer's specified clamping requirements. Inspect the cutting edges for damage before each use, and do not exceed the tool's rated depth-of-cut range of 0.200 to 0.300 inches.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.0781 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inch (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.200 to 0.300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eCoating\/Finish\u003c\/strong\u003e: nACRo\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\u003eWeight\u003c\/strong\u003e: 0.5 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: 12178960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747623960882,"sku":"12178960","price":30.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67947fef5be1d9d27fd9395347a749e2.jpg?v=1788883654","url":"https:\/\/voomisupply.com\/products\/accupro-12178960-square-end-mill-5-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
