With a 0.05-inch (3\/64-inch) cutting diameter and a 0.25-inch length of cut, this tool is built for tight-tolerance work in small-feature milling. The AlTiN coating extends tool life in high-heat cutting environments, including hardened steels and heat-resistant alloys. Three flutes and a 30-degree helix angle balance chip evacuation with surface finish quality. The 0.125-inch shank diameter and 2.5-inch overall length make it compatible with standard collet setups on vertical machining centers and CNC mills. It is a centercutting tool capable of plunge entry. Installed by machinists and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for small-feature profiling, slotting, and contouring operations where tight tolerances are required. The compact 0.05-inch diameter targets micro-milling applications in mold and die work, medical component machining, and precision part production. Right-hand cut and right-hand flute geometry follow standard spindle configurations on the majority of CNC machining centers in production and job shop environments. The fixed helix angle of 30 degrees is optimized for consistent chip flow in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.05-inch (3\/64-inch) cutting diameter for small-feature and micro-milling work\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for extended tool life in high-temperature cutting applications\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances chip evacuation with surface finish performance\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes consistent chip flow and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilled holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/8-inch collet or collet chuck setups on CNC vertical machining centers and manual mills.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 0.125-inch shank fully in the collet and torque the collet nut to the collet manufacturer's specification. Verify runout with a dial indicator before commencing cuts, as runout is especially critical at small diameters where it can accelerate tool wear or cause breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.05 inches (3\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 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\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.03 inches L x 0.32 inches W x 0.32 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31850-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51733142995250,"sku":"31850-C3","price":69.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8812d2b2470bfaa489e415e80bcb36_8cc5d633-db0c-4624-b794-c5de80e732b4.jpg?v=1788751830","url":"https:\/\/voomisupply.com\/products\/harvey-tool-31850-c3-square-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
