Built from solid carbide, the tool delivers the rigidity and wear resistance required for high-speed machining applications. It features a 1\/8 inch (0.1250 inch) mill diameter, a 0.1160 inch length of cut, and an AlTiCrN coating that extends tool life by reducing heat buildup and oxidation at the cutting edge. The variable index geometry helps reduce harmonic chatter during cut, improving surface finish and dimensional accuracy. Machinists and CNC operators in production and job shop environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for finish and semi-finish milling passes on dies, molds, and complex workpiece geometries where a full-radius tip profile is required. The 1\/8 inch shank diameter makes it compatible with standard collet systems used on CNC machining centers and high-speed spindles. The 1-1\/2 inch overall length provides a compact, rigid setup that minimizes deflection in tight-tolerance work. Applications include contour milling, profile milling, and 3D surface finishing in steel, stainless, and hardened alloy materials where coating performance is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides superior rigidity and wear resistance compared to HSS tooling\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating improves heat resistance and extends tool life in ferrous and abrasive materials\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and improves surface finish at cutting speed\u003c\/li\u003e\n\u003cli\u003e4-flute geometry supports higher feed rates and better chip evacuation in finish milling\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1\/8 inch shank for use in standard collet chucks and toolholders\u003c\/li\u003e\n\u003cli\u003eCompact 1-1\/2 inch overall length minimizes deflection in precision setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and high-speed milling spindles equipped with standard 1\/8 inch collet or toolholder systems. Verify runout tolerance and collet condition before use to maintain dimensional accuracy at this diameter.\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, powered-down state before changing tooling. Seat the shank fully into the collet and torque the collet nut according to the toolholder manufacturer specifications. Confirm tool runout with a dial indicator before beginning a production cut, as runout at small diameters accelerates edge wear and can cause premature tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1160 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.018 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 41342320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734909485362,"sku":"41342320","price":68.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62db6a4b8f367ce8fd5b5ab681527b7d.jpg?v=1788767970","url":"https:\/\/voomisupply.com\/products\/accupro-41342320-ball-end-mill-1-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
