It features a 3\/8 inch cutting diameter, a 1\/2 inch length of cut, and a 2 inch overall length with a matching 3\/8 inch shank diameter. The AlTiN coating provides heat and wear resistance at elevated cutting temperatures, extending tool life in ferrous and hardened materials. A 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces. The micrograin carbide substrate supports high-speed feeds and speeds across a range of workpiece materials. Licensed machinists and CNC operators working in job shops or production environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill suits side milling, slotting, and finishing passes in ferrous metals, stainless steels, and high-temperature alloys where a tight diameter tolerance is required. The centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled pilot hole, adding operational flexibility. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining center spindles. The +0.000\/-0.002 inch mill diameter tolerance and -0.0001\/-0.0004 inch shank diameter tolerance support close-tolerance fits in collet chucks and end mill holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-flute configuration increases feed rates and improves surface finish compared to lower flute-count tools\u003c\/li\u003e\n\u003cli\u003eAlTiN coating resists heat and oxidation at high cutting speeds in ferrous and hardened workpiece materials\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes efficient chip evacuation and reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill for use in collet chucks, shrink-fit holders, and end mill holders accepting a 3\/8 inch shank diameter on CNC machining centers and manual knee 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 in a safe, locked-out state before changing tooling. Seat the shank to the recommended gauge-line depth in the holder and torque the retention hardware per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut; excessive runout will accelerate tool wear and reduce dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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, 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: 45 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\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: 0.115 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: 12177414\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728770171186,"sku":"12177414","price":63.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a1bbd4e56c25360a016a7ddd2d3fb0d.jpg?v=1788696055","url":"https:\/\/voomisupply.com\/products\/accupro-12177414-square-end-mill-3-8-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
