This single-end, center-cutting tool features a 0.1969-inch (5.00 mm) mill diameter, a 0.6299-inch (16.00 mm) length of cut, and four spiral flutes with a 40-degree helix angle. The AlTiN (Aluminum Titanium Nitride) finish extends tool life in high-temperature cutting environments. Micrograin carbide substrate provides wear resistance and edge retention in demanding milling applications. Licensed machinists and CNC operators use this tool in vertical machining centers and manual mills for slotting, profiling, and plunge cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for regular-length milling tasks in job shops, production machining, and toolroom environments. The right-hand cut and right-hand flute configuration is the standard orientation for conventional CNC milling setups. The center-cutting design allows direct plunge entry without a pre-drilled pilot hole. The 6.00 mm (0.2362-inch) shank diameter fits standard collet chucks and end mill holders used across most 3-axis and 4-axis machining centers. Typical applications include finish profiling, pocket milling, and contour work in steel, stainless steel, cast iron, and hardened alloys where AlTiN coating provides thermal and abrasion resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1969-inch (5.00 mm) mill diameter with mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 40-degree helix angle for efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for elevated heat resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability enables direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers consistent edge geometry and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration matches standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fitment solid carbide square end mill for use in collet chucks and end mill holders accepting a 6.00 mm shank diameter in vertical machining centers and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle drive before mounting or removing any cutting tool. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut to confirm proper seating and avoid premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1969 inches (5.00 mm)\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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.6000 - 0.7000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\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: 63.00 mm\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\u003c\/strong\u003e: AlTiN\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: 40 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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 12182438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738253099314,"sku":"12182438","price":46.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba6f75c57a55a8c5d3ede50fb735312b.jpg?v=1788797313","url":"https:\/\/voomisupply.com\/products\/accupro-12182438-square-end-mill-0-1969-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
