Built from micrograin carbide, this single-end tool runs a 45-degree helix angle with a spiral flute configuration, promoting efficient chip evacuation and smooth cutting action. At 0.1875 inches in diameter with a 0.5625-inch length of cut, it is sized for light, high-accuracy passes in tight geometries. The centercutting geometry allows plunge entry. Right-hand cut and right-hand flute orientation are standard. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, profiling, and pocket milling in applications where a small-diameter, high-flute-count tool is required. The 6-flute design increases feed rates compared to 2- or 4-flute alternatives at equivalent chip loads, making it a practical choice for finishing passes and semi-finish operations in ferrous and non-ferrous materials. The 2-inch overall length keeps the tool compact and rigid, reducing deflection risk in close-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e6 flutes with 45-degree helix angle for improved surface finish and chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry\u003c\/li\u003e\n\u003cli\u003eSpiral flute design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker, no variable helix — consistent edge geometry throughout cut length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill for use in CNC machining centers, manual mills, and collet-style toolholders accepting a 0.1875-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup personnel. Secure the shank fully in a collet or end mill holder before operation, ensuring the holder is clean and free of chips that could affect runout. Confirm spindle speed and feed rate are appropriate for the workpiece material and cut depth before engaging the tool. Never exceed the rated length of cut when taking full-depth passes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\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: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5625 inches (9\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.5000 - 0.6000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\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\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003c\/strong\u003e: Uncoated\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\u003ePackage Weight\u003c\/strong\u003e: 0.029 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: 12177401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755361829170,"sku":"12177401","price":44.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6926aca9de6f8d00683d53c91af9e391_8b7acf09-a4b7-454a-8196-7598bb0c1fb3.jpg?v=1788954136","url":"https:\/\/voomisupply.com\/products\/accupro-12177401-square-end-mill-3-16-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
