Measuring 0.4687 inches in diameter with a 1 inch length of cut and a 3 inch overall length, this tool fits a standard 1\/2 inch shank. The nACRo (nano-composite) coating reduces heat buildup and extends tool life in abrasive cutting conditions. Four spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth surface finishes. Micrograin carbide construction provides the hardness and toughness needed for demanding milling operations. Centercutting geometry allows plunge entry, adding flexibility in toolpath programming.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills in tool rooms, job shops, and production environments. It handles slotting, profiling, and pocketing operations in steel, stainless steel, cast iron, and similar materials. The right-hand cut and right-hand flute orientation match standard spindle configurations. Its 40-degree helix makes it well suited for finishing passes where surface quality matters. Machinists and CNC operators working with hard metals at moderate-to-high speeds will find this geometry effective for maintaining tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003enACRo finish coating for reduced friction and extended tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip evacuation and improved surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes with right-hand cut and right-hand flute direction\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 an OEM-style replacement or direct-use solid carbide square end mill compatible with standard 1\/2 inch collets and end mill holders on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Seat the 1\/2 inch shank fully in a clean, properly sized collet or end mill holder and torque the retention mechanism to the tool holder manufacturer's specification. Inspect the cutting edges and coating before use and confirm runout with a dial indicator when tight tolerances are required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 15\/32 inch (0.4687 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\/Coating\u003c\/strong\u003e: nACRo\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: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\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\u003eExtended Reach\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\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: 12178986\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727368814898,"sku":"12178986","price":124.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/956f5897da136d5317737e59273360e6.jpg?v=1788676852","url":"https:\/\/voomisupply.com\/products\/accupro-12178986-square-end-mill-15-32-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
