Built from micrograin solid carbide, the tool delivers rigidity and wear resistance across demanding cutting conditions. The 0.375-inch diameter cutting edge pairs with a 40-degree helix angle and four spiral flutes to promote chip evacuation and reduce heat buildup. An AlTiN coating further extends tool life by providing thermal and oxidation resistance at elevated cutting temperatures. This end mill is intended for use by machinists and tool-and-die professionals on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill suits high-speed finish milling, contour work, and profiling applications in job shop, toolroom, and production environments. The ball nose geometry makes it well-suited for 3D surface contouring, die cavities, and radius-bottom slot work. With a 0.875-inch length of cut and 2.5-inch overall length, it fits standard toolholders used in vertical and horizontal machining centers. The right-hand cutting and right-hand flute direction are consistent with conventional CNC spindle configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides thermal resistance and reduces tool wear in high-temperature cuts\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes deliver a smooth finish on contoured and profiled surfaces\u003c\/li\u003e\n\u003cli\u003eBall nose geometry suited for 3D contouring, die work, and radius-bottom features\u003c\/li\u003e\n\u003cli\u003eSingle-end design with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard toolroom end mill for CNC machining centers and manual mills accepting a 0.375-inch shank diameter in ER, hydraulic, shrink-fit, or Weldon-style toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Verify toolholder runout with a dial indicator before cutting to prevent premature tool failure. Follow the machine manufacturer and cutting tool manufacturer guidelines for feeds, speeds, and depth of cut for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.139 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: 12177123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731874480434,"sku":"12177123","price":79.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ccf1fb081b1f1d766f0307a85942659.jpg?v=1788735936","url":"https:\/\/voomisupply.com\/products\/accupro-12177123-ball-end-mill-0-375in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
