Built from micrograin carbide and finished with an AlTiN (aluminum titanium nitride) coating, this tool delivers heat resistance and extended tool life at elevated cutting speeds. The 6-flute geometry provides more cutting edges per revolution, which improves surface finish and allows higher feed rates compared to 4-flute designs. With a 40-degree helix angle and spiral flute configuration, it generates smooth chip evacuation and reduces chatter. Centercutting capability allows plunge entry directly into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining ferrous metals, hardened steels, stainless, cast iron, and similar difficult-to-machine materials where AlTiN coating provides a thermal barrier. The long-length-of-cut designation (1.125 inches) makes it useful for deeper pocketing, slotting, and profiling operations where standard-reach tools fall short. It is a single-end, right-hand cut, right-hand flute tool intended for use in vertical and horizontal machining centers as well as manual knee mills running appropriate spindle speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN finish for heat resistance in high-speed ferrous and hardened material machining\u003c\/li\u003e\n\u003cli\u003e6-flute spiral geometry for improved surface finish and higher feed rates\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces vibration\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eLong length-of-cut classification at 1.125 inches for deeper pocketing and profiling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 1\/4 inch collets, end mill holders, and hydraulic tool holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the shank in a clean, properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer guidelines. Inspect the collet bore and shank for contamination before seating the tool, as debris causes runout and premature edge wear. Set spindle speed and feed rate per the material being cut and the tool manufacturer cutting data for 6-flute carbide end mills. Never run a solid carbide tool in a worn or undersized collet, as grip inconsistency causes tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eLength Type\u003c\/strong\u003e: Long\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: 0.14 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: 12183877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738354254130,"sku":"12183877","price":55.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f06808265f5abe8af820a2998acdf831.jpg?v=1788798557","url":"https:\/\/voomisupply.com\/products\/accupro-12183877-square-end-mill-1-4-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
