Built from micrograin carbide, it measures 0.1969 inches (5 mm) in cutting diameter with a 0.3937-inch (10 mm) length of cut and a 40-degree helix angle that promotes aggressive chip evacuation and reduced cutting forces. The AlTiN coating provides high heat resistance, making this end mill well-suited for dry machining and high-speed applications. At 0.1 pounds, it is a single-end, centercutting tool with a right-hand cut and right-hand spiral flute configuration. It is typically installed and operated by CNC machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for extended-reach applications, with a 60 mm reach length and a 0.2362-inch (6 mm) shank diameter. It fits standard collet chucks and end mill holders used in vertical machining centers and CNC milling machines. Typical applications include slotting, profiling, and pocket milling in steel, stainless steel, cast iron, and similar materials where a small-diameter, high-performance tool is required. The centercutting geometry allows plunge entry into workpieces without a pre-drilled hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating supports dry and high-speed cutting with strong thermal resistance\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip flow and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 60 mm reach length for deep cavity and pocket work\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge milling without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for CNC machining centers and manual mills accepting a 0.2362-inch (6 mm) shank diameter with standard collet or end mill holder tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with CNC toolholding systems. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge line and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1969 inches (5 mm)\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: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\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: 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\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: 0.102 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12177208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747767025970,"sku":"12177208","price":96.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a51acd721b3e4a0472985b85947fb587.jpg?v=1788885241","url":"https:\/\/voomisupply.com\/products\/accupro-12177208-square-end-mill-0-1969-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
