With a 0.2188 inch (7\/32 inch) mill diameter and a 4-flute spiral configuration, it delivers smooth chip evacuation and consistent surface finishes in ferrous and non-ferrous materials. The 40-degree helix angle promotes efficient cutting action and reduced chatter. At 3.0 inches overall length with a 0.5625 inch length of cut, this double-end tool offers extended service life by providing two usable cutting ends. It arrives uncoated and ready for use in compatible CNC machining centers and manual milling equipment.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for profiling, contouring, slotting, and finishing passes in precision machining environments. The double-end configuration makes it practical for shops looking to maximize tool life per unit. Right-hand cutting and right-hand flute direction are standard for conventional spindle setups. The 3\/8 inch shank diameter fits common collet and end mill holder sizes found in both vertical and horizontal milling machines used in general manufacturing, tool-and-die, and mold work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design provides two cutting ends, extending overall tool life\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration for improved surface finish and chip flow\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle reduces cutting forces and minimizes chatter\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids on a range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit cutting tool for CNC and manual milling machines accepting a 3\/8 inch shank diameter end mill holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with end mill holder torque procedures and runout inspection. Ensure the spindle is fully powered down and locked out before changing tooling. Confirm collet or holder bore size matches the 3\/8 inch shank before securing. Inspect the cutting edges for chips or damage before each use, and apply appropriate cutting fluid or coolant as required by the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2188 inches (7\/32 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: 0.5625 inches (9\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\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: Solid Carbide\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: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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\u003eLength Type\u003c\/strong\u003e: Regular\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: 12177742\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746890744114,"sku":"12177742","price":154.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4beb57075d945944968f535a29807c12_c0e4cd97-8348-41ea-92e7-e6978cccfad5.jpg?v=1788874380","url":"https:\/\/voomisupply.com\/products\/accupro-12177742-ball-end-mill-0-2188-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
